144.390 FM APRS balloon heads for UK

Thursday 26th February 2015

The solar powered around-the-world high altitude balloon was released by the California Near Space Project team on Monday, February 23 and is expected to reach the UK on Friday. The APRS beacon should have a radio range of up to 400 km.

The amateur radio APRS frequency is not standardized world-wide. The USA uses 144.390 MHz while the British Isles and Europe use 144.800 MHz. It is understood the balloon will change frequency to 144.800 MHz when it reaches this side of the Atlantic.

Predicted track of CNSP-22

New Digital TV Repeater for Kent

Thursday 26th February 2015

Justin G8YTZ is delighted to announce that authorisation and NOV has been received from OFCOM approving a new Digital Amateur TV Repeater at Selling Minnis, between Ashford and Dover, Kent.

The Digital TV repeater GB3DK will use the bandwidth efficient DVB-S2 format with 2 transport streams using 8PSK modulation format; though complicated to transmit, does have the advantage of requiring simple receiving equipment (an old DVB-S2 Satellite Receiver and pre-amp and a 23cm antenna is all you need to receive GB3DK) and therefore encouraging the up-take of ATV in the south-east.

The ERP will be +13dBW to ensure good coverage from the proposed Omni-Directional antenna.

The input will be on 1260MHz and the output on 1302MHz. I look forward to "seeing" you all on the new repeater!

I would especially like to thank Noel Matthews G8GTZ for his help in obtaining the license NOV for this exciting new repeater.

Local DAB radio trials

Wednesday 25th February 2015

Ofcom has announced trials of a new technology that could provide small radio stations across the UK with an affordable way to broadcast on DAB digital radio

If the trials are successful, UK radio listeners could benefit from more local and community radio stations on DAB.

Currently, the cost of broadcasting on DAB is beyond the reach of many small radio stations.

But a new approach, pioneered by Ofcom engineer Rashid Mustapha, means that small scale radio stations could start broadcasting on DAB radio for a fraction of current costs.

The new approach is cheaper than current systems because it uses software freely available from http://opendigitalradio.org rather than relying on often expensive hardware equipment. Known as ‘small scale DAB’, it is best suited for broadcasting to small geographic areas, ideal for community and local radio stations.

Ofcom has confirmed plans for up to ten trials of small scale DAB across the UK.

Each trial will allow new digital radio services to broadcast to a local area and will help explore how groups of radio stations can work together.

The trials will also inform Ofcom’s work on identifying suitable frequencies for broadcasting smaller digital stations and help understand how these services could be licensed.

Ofcom is today inviting applicants to take part in the trials, which are expected to run for nine months. The deadline for applications is 3pm on April 7, 2015.

Claudio Pollack, Ofcom Consumer and Content Group Director, Ofcom, said: “We’re looking for local and community radio stations to take part in trials to test this innovative new technology.”

“If successful, this could significantly benefit digital radio listeners up and down the country.”


The Department for Culture, Media and Sport is funding Ofcom’s work on how small stations could access DAB digital radio.

Chinese rocket body disintegrates over North America

Wednesday 25th February 2015

On Monday night, Feb. 23-24, observers across the western half of North America witnessed a spectacular cluster of bright lights in the sky. It was the re-entry and disintegration of a Chinese rocket body.

Coincidentally, a geomagnetic storm was in progress at the time and more than one photographer caught the rocket's debris cutting across curtains of Northern Lights.

Amateur radio based group rescues released broadcast frequency

Monday 23rd February 2015

When the 'Deutsche Welle' decided to close down one of their 500 KW short wave broadcast transmitters near Munich at the end of 2012, a group containing some German radio amateurs applied for and were allocated the then available short wave frequency of 6070 KHz in 2013.

This group now have an operational 10KW station on the frequency, using the driver stages from the old Deutsche Welle transmitter. The rest of the transmitter was built by and is run by Rainer DB8QC . The licence allow transmission 24/7 but at present most transmissions are on a weekend during daylight hours.

Content is mainly provided by existing Internet Radio stations wanting to get their material "on-the-air" this includes several soceities that remember the days of the Pirate Radio pop music stations in the North sea between England and Holland and a lot of their music content is from the 60's and 70's.

Additional content is being sought and at only 15 Euros an hour, this is not a corporate big business rather a facility where smaller groups can afford to buy time to transmit their content. One such group is the Deutsche Amateur Radio Club, the National Amateur Radio Soceity in Germany, who hope to have a weekly 2 hour slot on the station from mid-March to send a DX orientated program, probably from 6pm local time on Sundays.

The DARC DX magazine will be in the German language and targeted towards German speaking listeners. Amateur radio is an international medium however so there are thoughts of also producing an international / English hour in addition, to reach out across Europe not only to radio amateurs but also to short wave listeners and the general public.

When I talked with another Rainer DF2NU who is one of the group running the station and the president of the Munich South section of the DARC, he told me that they hope to be able to broadcast more often once sufficient content is available however they are already seeing other broadcasters such as Radio China moving onto the frequency in the evenings as those stations percieve 6070 KHz as a free frequency.

Rainer told me that currently "Channel 292" has airtime bookings for 20-25 hrs a week, mostly on weekends at which times it runs at 10 kW output. When the station is idle (as there is no booking), the transmitter power is reduced to 1kW and transmits an infinite music-loop with no actual program. Late evenings, after 8pm local, the transmitter is switched off completely in order to save energy costs. Rainer stressed that the license is for 24/7 so they can use the frequency at any time when they have content.

With a current rate of EUR 15,-- per hour airtime you cannot earn any money. This broadcast station is an extenion of the amateur radio hobby and the group seek to simply cover their costs.

Thinking back to the very start of amateur radio, Hams were allowed to transmit music, news and entertainment programs, so it's nice to see some of this coming back onto the short wave bands thanks to the efforts of groups like this one.

I wonder as we see more and more broadcasters leaving the short wave bands in favour of Internet broadcasting, whether we'll see more licences and surplus transmitters being picked up by amateur radio groups? This seems to be somewhat of a repeat of the situation when it was said 200 metres and up is useless for broadcasting - give it to the amateurs. We all know what then followed.

Perhaps amateur Radio groups around the world can put new life into released shortwave broadcast frequencies?

For program information about "Channel 292" simply go to their website at www.channel292.de

Why not give 6070KHz AM a listen?

The Channel292 station covers a lot of Western Europe but has also been heard in Russia and the US

VI8ANZAC is on the air

Monday 23rd February 2015

The Darwin Amateur Radio Club (DARC) continues to be active with the VI8ANZAC callsign to mark the Albert Chalmers Borella journey re-enactment - and has caused many dog-piles on the bands.

DARC President Gary Gibson VK8GN reports that concentration has been on 40m, 20m, 15m and 10m. The lower bands are a bit of a challenge during the Australian northern wet season with very high noise levels.

There have been good openings to Europe on 10m, and many other countries including VK are being worked all the bands.

High interest has been generated in VI8ANZAC going by the large number of look-ups on QRZ.com

The commemorative event marks the historic trek to enlist in WWI by Albert Borella. The 33 year old went from Tennant Creek to Darwin which then had no sign-up point, and on to Townsville in Queensland by boat for enlistment.

Albert Borella served at Gallipoli in 1915 for two months, before going to the Western Front in France and Belgium.

He was wounded in action, decorated with the Military Medal, mentioned by Winston Churchill in military dispatches, and for valour in combat - awarded the Victoria Cross.

Each April 25 is ANZAC Day in Australia, to honour those who fought for the first time as the Australian and New Zealand Army Corp (ANZAC) at Gallipoli in Turkey, then elsewhere, and the service men and women in all subsequent conflicts.

This year is the Centenary of ANZAC. A number of events are being held in Australia and aboard. The Darwin Amateur Radio Club has the WIA ANZAC 100 callsign VI8ANZAC until March 3.

SDR Net - On the Move

Monday 23rd February 2015

The South Dublin Radio Club Net (SDR Net), which has been operating, for over 2 years on 40 meters on a Sunday morning following the IRTS 40 Meter News, is on the move.

It will now be on 7.123MHz +/- QRM and will run from 10 am to 11 am, prior to the IRTS 40 Meter news.

All EIs are welcome to call-in and it is hoped that by having a fixed time, that this change will afford other EI, especially those that may be waiting for the IRTS News, will join in and help expand both the coverage and participation in the SDR Net.

Libraries exposure for Amateur Radio

Saturday 21st February 2015

Three metropolitan Melbourne primary school libraries now have practical lessons on Amateur Radio, thanks to library technician Julie Gonzales VK3FOWL. The exercise has been a real success.

Julie VK3FOWL operates from the libraries to introduce Amateur Radio to students from 8 to 11 years of age.

Each month a different group of six students is invited to the fun lunchtime program of learning and practicing the basics of Amateur Radio.

Julie VK3FOWL has prepared a booklet which covers callsigns, operating procedures, Morse code, Q-codes and log keeping.

Outdoor activities like antenna building and Amateur Radio Direction Finding are also offered. The feedback from principals, parents and students has been so positive.

Putting youngsters before a microphone for the first time, and exposing inquiring minds to hands-on technology, can be very rewarding.

Julie encourages other radio amateurs associated with primary schools to give it a go. She suggests contact the school principal first. More information is available from Julie VK3FOWL on request.

The School Amateur Radio Clubs operate on 40m and 2m at lunch times on Mondays, Tuesdays and Thursdays. Julie is interested in starting a net on 40m so her 'city’ primary school students can talk to a ‘regional’ primary school, say in VK3, or maybe VK5 or VK7.

Are there any radio amateurs associated with regional primary schools in those states? What a great idea - let’s hope it catches on.

How to setup an AX25 Soundmodem

Friday 20th February 2015

George Smart M1GEO has recently published a couple of packet radio related articles on his website

Soundmodem is a Multiplatform Soundcard Packet Radio Modem written by Thomas Sailer, HB9JNX/AE4WA. The software allows a standard PC sound-card to be used as a packet radio "modem" with all processing done on the main computer CPU.

George describes how to get the basic network interface working and how that can be used with XASTIR, a amateur radio based digital communication system for real-time exchange of digital information to users on the APRS (Automatic Packet Reporting System) network, 144.8000 MHz in the British Isles and Europe, see
http://www.george-smart.co.uk/wiki/AX25_Soundmodem

He has been interested in APRS for years and here describes an Arduino TNC

Project ULTRA helped Alan Turing crack code

Thursday 19th February 2015

The Ottawa Citizen interviews Ernie Brown about his work in Project ULTRA during WWII

He is one of the last surviving members of a crack team of radio interceptors who were stationed in a secret building in the nation’s capital during the Second World War under a classified program codenamed ULTRA. There, they intercepted coded enemy messages, and relayed them back to the UK.

ARRL warns experimental licensee to avoid interference to HF ham activity

Wednesday 18th February 2015

The ARRL has asked a Massachusetts company that plans to conduct experimental transmissions over wide portions of the HF spectrum either to avoid Amateur Radio allocations or to announce the times and frequencies of their transmissions in advance.

The FCC last fall granted MITRE Corporation of Bedford, Massachusetts, a 2-year Part 5 Experimental License, WH2XCI, to operate 21 transmitters at 10 fixed New York and Massachusetts sites. MITRE plans to test wideband HF communication techniques on a variety of bands between 2.5 MHz and 16 MHz.

"[I]t will not be possible for MITRE to operate these transmitters within the Amateur Radio Service allocations...without causing harmful interference to a large number of Amateur Radio operators on an ongoing basis," ARRL Chief Counsel Chris Imlay, W3KD, said in a February 12 letter to MITRE.

Imlay said that if MITRE does not agree to avoid ham radio bands or to announce times and frequencies of transmissions ahead of time, it will ask the FCC to rescind the company's Experimental License or to impose a prior notification requirement "in real time for each and every use of the transmitters authorized at each site."

The WH2XCI Experimental License authorizes maximum bandwidths of 5 kHz, 500 kHz, and 1 MHz at effective radiated power levels of 6 W, 24 W, or 122 W. MITRE has indicated that most bandwidths would be between 100 and 300 kHz.

"At these power levels with the operating parameters proposed, it will be impossible to conduct your tests at any time within the Amateur Radio allocations and, at the same time, avoid harmful interference," Imlay said. He noted that MITRE already conceded this point in a technical exhibit submitted to the FCC with respect to its 1 MHz bandwidth mode.

Imlay said that when interference from MITRE's wide-bandwidth transmitters "inevitably occurs in the narrow-bandwidth, sensitive receivers" hams use, amateur licensees will have no way to determine the source of the interference or know to whom they might complain.

"Thus, your assurance of operation on a 'non-interference basis' is meaningless under the circumstances, and yet that is both a special condition of operation" of the WH2XCI license and under FCC Part 5 regulations, Imlay told MITRE.

"It is ARRL's intention to ensure that this experimental authorization, improvidently granted to the extent that it includes heavily used Amateur Radio allocations, is not permitted to cause interference to ongoing Amateur Radio HF communications," Imlay concluded.

MITRE obtained the Experimental License to investigate high data rate wideband HF communication systems that exploit polarization diversity multiple input, multiple output concepts to expand the bandwidth of the communication channel.

ARRL warns MITRE over HF Broadband

Sunday 15th February 2015

On January 18th, we reported on the plans of MITRE to broadcast wideband on HF. Now the ARRL has issued a warning to the company

The ARRL has asked the Massachusetts company that plans to conduct experimental transmissions over wide portions of the HF spectrum either to avoid Amateur Radio allocations or to announce the times and frequencies of their transmissions in advance.

The FCC last fall granted MITRE Corporation of Bedford, Massachusetts, a 2-year Part 5 Experimental License, WH2XCI, to operate 21 transmitters at 10 fixed New York and Massachusetts sites. MITRE plans to test wideband HF communication techniques on a variety of bands between 2.5 MHz and 16 MHz.

“[I]t will not be possible for MITRE to operate these transmitters within the Amateur Radio Service allocations…without causing harmful interference to a large number of Amateur Radio operators on an ongoing basis,” ARRL Chief Counsel Chris Imlay, W3KD, said in a February 12 letter to MITRE.

USA to propose additional sharing of 10 GHz ham band

Sunday 15th February 2015

The ARRL report the the USA is to propose the use of 9.9-10.5 GHz for the Earth Exploration Satellite Service

US proposal for World Radiocommunication Conference 2015 (WRC-15) Agenda Item 1.12 — to expand the Earth Exploration Satellite Service (EESS) in the vicinity of 10 GHz — supports allocating an additional 600 MHz of spectrum to the EESS (active) as a primary allocation in the frequency band 9.9-10.5 GHz, with certain limitations.

The Amateur and Amateur-Satellite services have secondary allocations of 10.0-10.5 GHz and 10.45-10.5 GHz, respectively; the only current primary allocation is to Radiolocation. A study conducted by a Working Party of the International Telecommunication Union Radiocommunication Sector (ITU-R) concluded that the interference potential of EESS (active) to Amateur Radio was limited to very brief and infrequent periods.

“In this hotly contested frequency range, the best we can hope for is that sharing partners will be compatible with continued amateur access, and that is the case here,” ARRL CEO David Sumner, K1ZZ, commented.

EESS use of the 9900-10,500 MHz band would be limited to systems requiring necessary bandwidths greater than 600 MHz that cannot be fully accommodated within the 9300–9900 MHz band.

The Deep Space Climate Observatory

Sunday 15th February 2015

For years, space weather forecasters have worried about the aging ACE spacecraft, which provides early warnings of CMEs and other solar storms bearing down on Earth. Launched in 1997, ACE could fail at any moment, leaving us blind to incoming storms.

Radio Astronomy and SDR Dongles

Sunday 15th February 2015

David Morgan 2W0CXV has released several papers covering the use of the RTL-SDR Dongle in radio astronomy

In 2011 David described the equipment configuration and software involved in setting to work a small 3m diameter amateur radio telescope using the FUNcube Dongle Pro software defined radio receiver.

At the end of 2014 he published a paper dealing with the setting up and use of a RTL-SDR dongle to receive meteor pings from the Graves Radar on 143.050 MHz.

He has now released two new papers covering the measurement of signal strength and RF noise sources with the RTL-SDR.

IARU President is new SOTA Mountain Goat

Saturday 14th February 2015

One of the latest amateurs to attain Mountain Goat as an activator in the popular Summits on the Air programme will be a familiar figure to many in the amateur radio world.

This is because he managed to combine his interest in SOTA whilst at the same time holding the post of IARU Region 1 President.

Hans Blondeel Timmerman PB2T who was President up to October last year, has activated summits in no fewer than 15 different countries, spanning the globe. Being from one of the low countries does present some challenges to a SOTA activator but the opportunity to travel obviously came in useful for Hans.

Hans Blondeel Timmerman PB2T operating from HB/VD-022 Berneuse.
Sunshine and some luxury on the summit are highly appreciated!

He says “ In October 2012 Paul HB9DST introduced K2XYL and me to the wonderful world of Summits on the Air. In that same month I retired, which meant a bit more free time for hiking, one of my wife’s favourites, and amateur radio. I have always tried to combine amateur radio with travel. So far I have been active from 80 DXCC entities. SOTA gave me a new start. When there is a chance to operate from another SOTA association I’ll give it a try. Of course I am not unique in that respect and there are others who have an even higher association score.”

”A great opportunity to learn more about a country is to go & activate a SOTA with a local amateur. I have fond memories of my SOTA activities in South Africa, Ireland, Macedonia, Lebanon, Romania, Poland and Australia. In all these countries I had the pleasure of having the company of a local amateur with whom I could discuss the scenery, antenna’s, radios etc. Experiencing the local cuisine during or after the SOTA activity is highly recommended. In recent months I got too focused on reaching 1000 activator points, It’s now time for 1, 2, 4 and 6 point summits which must be as beautiful as their higher brothers.”


Congratulations Hans!

Mark Walmsley G0VOF

SOTA Associate Press Officer

Implementing TV White Spaces

Saturday 14th February 2015

Ofcom will allow a new wireless technology access to the unused parts of the radio spectrum in the 470 to 790 MHz frequency band

The new technology, known as white spaces devices, will share this band with the existing uses, Digital Terrestrial Television (DTT), including local TV, and Programme Making and Special Events (PMSE), including in particular wireless microphone users.

The sharing will take place dynamically, controlled by databases which will hold information on the location of DTT and PMSE users and white space devices. They use this information, following the approach set out in this document, to allow white spaces devices access to the spectrum band, but only to the extent that this does not cause harmful interference to the existing users of the spectrum.

Implementing the decisions set out in this document is one of the ways Ofcom is meeting the increasing demand for more spectrum to deliver existing and new services. Our objective is to complete the implementation of our decisions so the new technology can be deployed by the end of 2015.

Teenager charged with Wireless Telegraphy Act offences

Thursday 12th February 2015

Ofcom have shown they can take action under the Wireless Telegraphy Act when they wish to

From the Scotland Police website:
http://www.scotland.police.uk/whats-happening/news/2015/
february/man-arrested-under-the-wireless-telegraphy-act


Police in Edinburgh have arrested and charged an 18-year-old man for over twenty offences committed under the Wireless Telegraphy Act.

The crimes, which included offensive remarks, took place between June 2014 and January 2015. They related to interference with communications on private radio networks that caused disruption to various locations in the Capital, including Edinburgh Airport and Edinburgh Castle.

As a result of five months of partnership investigation between the local Community Policing Team, Ofcom and the British Transport Police, an address at Craigmillar was searched on Monday (February 9) and equipment was recovered.

The matter is now being reported to the Procurator Fiscal.

Inspector Murray Starkey said:

“This type of crime may appear relatively low risk, however, the impact has caused genuine concern for the individuals and organisations involved, as well as significant disruption to their daily business.

“Our joint investigations have led to a man being charged with over twenty offences. This demonstrates the value of our partnership with Ofcom and is an example to others that perpetrators of these crimes will be traced and held to account.”

Mark Walls, Ofcom Spectrum Engineering and Enforcement Director, said:

“Deliberately interfering with private radio networks can cause severe disruption and distress. We worked closely with the Community Policing Team and the British Transport Police to thoroughly investigate and bring the illegal interference to an end.”

Anyone who has further information about these crimes is asked to contact Police Scotland on 101.

New version of DXMonitor

Thursday 12th February 2015

Peter, VE3SUN , has released an updated version of his extremely useful programme DXMonitor.

DXMonitor is a standalone Windows program which monitors the DX announcements available on the internet at DX Summit, HB9DRV and connections to one or more local and international DX Cluster Telnet Servers.

New DX spots are displayed in the main window with user selectable bands, fonts, colors, and highlighting of alerts and local spotters. A band map tracks the current stations on the air by frequency. Maps show the openings with buttons to select bands and times.

The predicted signal strength of the spotted station at your QTH can be displayed with each spot. A 24 hour propagation prediction by band takes only one click.

DX Monitor builds a database of DX Spots, Announcements, and WWV information and includes many tools which can be used by DXers to improve their chances of working a new country.

The latest improvement enables import of spots from DXSummit from as far back as 1994 up to the current date, with time, date, band, callsign and many other filters.

The latest beta version is here.

FCC seeks comment on radar sharing schemes that could displace Amateur Radio at 76-81 GHz

Wednesday 11th February 2015

The FCC is seeking comment on issues involving expanded use of various radar applications in the 76-81 GHz band, which Amateur Radio shares with other services.

The band 77.5-78 GHz is allocated to the Amateur and Amateur Satellite services on a primary basis, and to the Radio Astronomy and Space Research services on a secondary basis.

"We undertake this proceeding to expand the available spectrum for radar operations in the 76-81 GHz band," the FCC said in a detailed Notice of Proposed Rulemaking and Reconsideration Order (NPRM&RO), released February 5 in ET Docket 15-26. The Commission said the proposals include allocation changes as well as provisions "to ensure that new and incumbent operations can share the available frequencies in the band."

The NPRM&RO can be found in PDF format on the web at,
http://transition.fcc.gov/Daily_Releases/Daily_Business/2015/
db0205/FCC-15-16A1.pdf

The FCC NPRM&RO is in response to a Petition for Rulemaking (RM-11666) filed in 2012 by Robert Bosch LLC and to two petitions for reconsideration of the Commission's 2012 Report and Order (R&O) addressing vehicular radar systems in the 76-77 GHz band. ET 15-26 incorporates earlier proceedings.

Among many issues, the FCC seeks comment on the possibility of reallocating the Amateur Radio and Amateur Satellite services from 76-81 GHz, and it asks for suggestions on "alternative spectrum that we might make available in this general region."

Bosch's 2012 Petition sought to modify the FCC's Part 15 rules to expand the operation of unlicensed vehicular radar systems from 76-77 GHz to the 76-81 GHz band to develop short-range radar (SRR) applications. The Bosch petition received "general support from the automotive industry," the Commission said.

In its petition, Bosch said that it anticipated no interference issues between Amateur Radio operations and vehicular radar operations at 77-81 GHz. "It notes that it is unconvinced after several meetings with the technical staff of ARRL that there is any 'significant incompatibility,'" the FCC NPRM&RO recounted, "and describes how amateur operations in the band 'tend to be largely experimental, occurring in geographic areas such as mountaintops and other rural areas where motor vehicle operation is not typical.'"

The FCC noted, however, that it "has previously recognized evidence of potential interference conflicts" between Amateur Radio and vehicular radar systems in the 76-77 GHz band, and believes the potential for "similar compatibility issues" could exist above 77 GHz. More than 10 years ago the FCC suspended Amateur Radio and Amateur Satellite operation in the 76-77 GHz segment and recently extended the suspension.

"Our goal is to adopt rules that address amateur use, including Amateur Satellite use, within the 76-81 GHz band in a comprehensive and consistent manner," the FCC asserted.

The FCC said that to the extent commenters believe Amateur Radio can continue to use the 4 millimeter band, it seeks comments on "what additional rule modifications we would have to adopt to realize successful shared use of the entire band." One possibility the FCC raised was altering current amateur power limits in that portion of the spectrum. The Commission said it also wants to "develop a record on the types of amateur use, and the extent of such use, that is currently undertaken" at 4 millimeters.

The ARRL plans to comment in the FCC proceeding.

HRN video: Ham Radio and the Internet

Wednesday 11th February 2015

Radio Hams were 'early adopters' of the Internet, and were instrumental in developing the pre-internet Bulletin Board system, the landline based one, in addition to the Packet Radio system

But that doesn't mean all hams are now Internet experts.

In this episode, Rich Casey N5CSU (Gary's partner in 100 Years of Ham Experience) has a ton of tips and techniques for wringing more out of the Internet.

Rich has posted links to all the sites he talks about on his blog at:
https://richcasey.wordpress.com/

And one more thing. I needed a generic "The Internet" graphic for the title. I let Google do the work, and it found me all kinds of globes and webs with computer screens flying out of them. And then there was the comic I used from http://xkcd.com/

You'll probably have to pause the video to read it. They describe themselves as "A webcomic of romance, sarcasm, math, and language." Quite a potent combination, and I wish I were 1/100th as creative.

Radio ham discovers Raspberry Pi 2 Xenon flash glitch

Tuesday 10th February 2015

BBC News reports on the discovery by Essex radio amateur Peter Onion G0DZB that the Raspberry Pi 2 reboots when photographed using a Xenon flash

It appears a SMPS chip on the board is not light resistant.

Peter G0DZB is a regular at the Amateur Radio Skills Nights run by the Chelmsford Amateur Radio Society (CARS) where he demonstrates many practical aspects of amateur radio and occasionally brings along his Raspberry Pi.

The Skills Nights are held on the 3rd Monday of each month at 7pm in the Danbury Village Hall, Main Street, Danbury, Essex, CM3 4NQ. The next one takes place on Monday, February 16. It is free and everyone is welcome to attend.

US hams track down indoor marijuana growers causing radio interference

Sunday 8th February 2015

US ham radio operators are helping police catch indoor marijuana growers who are causing RFI interference.

An article in the February 4 Police One magazine says

"Reports have begun to flood into the National Association for Amateur Radio about interference with their ham radios from their neighbor’s marijuana grows. The most complaints come from California and Colorado, for obvious reasons. Many ham radio operators began to see a correlation with marijuana grows and this RFI.

One amateur radio operator located five marijuana grows near his house due to RFI alone! Many ham operators can locate a grow simply by taking a radio and portable antennae out into their neighborhood and using the radio to triangulate the exact location of the grow."

On Monday, February 9, ESA astronaut Samantha Christoforetti, IZ0UDF, will float into Europe's space ferry to install a special infrared camera, set to capture unique interior views of the spacecraft's break-up on re-entry.

The battery-powered camera will be trained on the Automated Transfer Vehicles forward hatch, and will record the shifting temperatures of the scene before it, explains Neil Murray, overseeing the project for ESA.

Recording at 10 frames per second, it should show us the last 10 seconds or so of the ATV. We dont know exactly what we might see - might there be gradual deformations appearing as the spacecraft comes under strain, or will everything come apart extremely quickly?

Our Break-Up Camera, or BUC, flying for the first time on this mission, will complement NASAs Reentry Break-up Recorder.

Whatever results we get back will be shared by our teams, and should tell us a lot about the eventual reentry of the International Space Station as well as spacecraft reentry in general.

Every mission of ESAs ATV ferry ends in the same way filled with Space Station rubbish then burning up in the atmosphere, aiming at a designated spacecraft graveyard in an empty stretch of the South Pacific.

But the reentry of this fifth and final ATV is something special. NASA and ESA are treating it as an opportunity to gather detailed information that will help future spacecraft reentries.

Accordingly, ATV-5 will be steered into a shallow descent compared to the standard deorbit path.

This ATVs fiery demise will be tracked with a battery of cameras and imagers, on the ground, in the air and even from the Station itself, and this time on the vehicle itself.

ESAs camera will not survive the reentry, expected to occur some 80-70 km up, but it is linked to the SatCom sphere with a ceramic thermal protection system to endure the searing 1500C.

Once SatCom is falling free, it will transmit its stored data to any Iridium communication satellites in view.

Plunging through the top of the atmosphere at around 7 km/s, it will itself be surrounded by scorching plasma known to block radio signals, but the hope is that its omnidirectional antenna will be able to exploit a gap in its trail.

If not, signalling will continue after the plasma has cleared somewhere below 40 km altitude.

Japans i-Ball camera managed to gather images of its Station supply ferry breaking up in 2012. Another i-Ball was planned to fly with ATV-5, but was lost in the Antares rocket explosion last October.

New open source data mode FSQ

Sunday 8th February 2015

Con Wassilieff ZL2AFP has developed a new fast simple chat data mode for use on HF and VHF

FSQ is a Fast Simple QSO mode for MF/HF. It works well under NVIS and sunrise/sunset conditions on the lower bands, and also works well for short skip on higher bands. It can also be used on VHF FM, and clearly has a much wider useful range of operating conditions that other more conventional digital modes. Sending speed can be varied between 20 and 60 WPM.

FSQ is designed for simple but effective 'Chat' operation, rather like phone text messaging or Skype™ chat; fast and easy to use. You don't use 'overs' as you would with a conventional digital or voice mode. It is highly suited to net operation. You just type a sentence and press Enter.

An important factor in the design of FSQ is that no synchronising process is required to locate and decode the received characters. Lack of sync means that reception is much less influenced by propagation timing changes that affect almost all other modes, since timing is quite unimportant; it almost completely eliminates impulse noise disruption; and it also contributes to very fast acquisition of the signal (decoding reliably within one symbol of start of reception). Fast acquisition removes the need for addition of extra idle characters at the start of transmission, and this leads to a very slick system. Add high resistance to QRM and QRN, thanks to the low baud rate, and you have a system so robust that it does not need error correction.

Sensitivity is believed to be about -13 dB SNR at 6 baud, and -16 dB SNR at 3 baud. That's about 10dB better and several times faster than 12 WPM Morse.

FSQ is NOT compatible in any way with EXChat or DominoEX. While also a Chat mode, it uses a completely new and revolutionary protocol.

D-STAR, DMR and C4FM Repeater Maps

Saturday 7th February 2015

Radio amateurs use at least five different and incompatible amateur radio digital voice modes on the VHF/UHF bands, D-STAR, Motorola's DMR, dPMR, Yaesu System Fusion C4FM and FreeDV

Of those D-STAR, DMR and C4FM have widespread repeater networks and there is currently one dPMR repeater GB7RR.

Yaesu supply the DR-1XE dual band repeater which can operate in both Digital SystemFusion (C4FM) mode and the traditional Analogue FM mode. It features an Automatic Mode Selection function.
https://www.hamradio-shop.co.uk/amateur-radio-shop/c4fm-digital-fusion/yaesu-dr-1-xe/

FreeDV was initially developed for HF but is now being used at VHF as well. It is a free software solution for digital voice making use of your PC's soundcard, see
http://freedv.org/

Maps showing the D-STAR, DMR and C4FM repeaters are available on the UK Repeater website.

Council attempts to use CEQA against radio ham

Friday 6th February 2015

Napa City Council is attempting to get a California Environmental Quality Act (CEQA) review of the amateur radio antenna mast belonging to Jeff Hullquist W6BYS

A few people living in the same neighborhood as Hullquist have waged a year-long campaign against his 16.76 meter (55 foot) antenna mast.

Council members agreed that limiting Hullquist’s hours of use likely clashed with federal law, which says radio operators must be reasonably accommodated. Limiting or restricting usage isn’t likely legal.

So on Tuesday the City Council asked for a California Environmental Quality Act (CEQA) review to determine what impact – if any – Jeff Hullquist’s tower at his Coombs Street home has on the cultural integrity of the historic Napa neighborhood.

Jeff Hullquist W6BYS said after the meeting that the environment study was a nonsense decision intended to harm him financially. He’s required to pay for the CEQA report, which could cost him thousands.

Depending on discussions with his lawyer, Hullquist said, he might take the matter to federal court.

WG2XPN 70 MHz Beacon update

Friday 6th February 2015

Brian WA1ZMS, licensee of the 3 kW ERP 70.005 MHz WG2XPN beacon, reports the license has been renewed until May 1, 2017

The Experimental License for WG2XPN with one-way only beacon operations on 70.005 MHz with 3 kW ERPd from here in the US (QTH: FM07fm) has been renewed until May 1, 2017.

As such, it gives the only 4m North American beacon a chance to be heard via TA in the Europe for another 2 years. That’s a good thing in my mind. Thanks again goes to the FCC & the Society of Broadcast Engineers here in the US for their continued support; after all this portion of spectrum is still reserved for TV service only and no US 4m ham band appears possible in the future.

I am always hoping for a repeat of the 7000+km Eskip DX reports that took place in 2013. To all EU stations on 4m: Remember to point your beams West during Eskip season and give a long listen on 70.005MHz. You might just hear something!

End of BBC World Service on 1323 kHz

Thursday 5th February 2015

The BBC World Service English is to end medium wave radio services to Eastern Mediterranean on 1323kHz in April

The BBC announced on February 3 that the English language radio service in the Eastern Mediterranean - including Israel, much of Lebanon, Cyprus and southern Turkey - will end on 25 April 2015.

Director of BBC World Service, Fran Unsworth, says: “Our English language service will still be available via satellite and on the internet - which is increasingly how our audiences tune in. However, we cannot identify a financially viable method by which to continue the medium wave radio service. It is for this reason that we have decided to end these transmissions.“

Audiences in the region will be able to listen to BBC World Service English 24 hours day through the direct-to-home satellite service on Eutelsat 13 (13 deg East, 11,117 MHz Vertical) or through the internet at BBCWorldservice.com

ISS ham radio SSTV in UK press

Thursday 5th February 2015

The Daily Mail reports that 22-year-old Radoslaw Karwacki received the recent amateur radio Slow Scan Television (SSTV) transmissions from the International Space Station

Radoslaw used an RTL-SDR dongle costing about £10 ($15) to receive the SSTV signal on 145.800 MHz FM on February 1. The antenna was a simple dipole and he used the free SDRSharp and MMSSTV software to receive and display the image.

'These images are not transmitted regularly. I was really lucky to receive them, because it was my first experience with this kind of equipment,' he told MailOnline.

'I blindly tuned in on that frequency during ISS flyby and happened to receive the signal.'

Wartime life as a Morse code operator

Wednesday 4th February 2015

94-year-old Connie Hird recalls her days as a Morse code operator during WWII

Connie did her initial training at Compton Bassett in Wiltshire.

She says this included sending and receiving Morse code messages and the assembling, repairing and full understanding of wireless sets in use at the time. After this in-depth training she progressed to a post at North West Central Communications Depot just off the old East Lancashire Road at Blackbrook near Wigan.

She describes the outward appearance of this extremely important centre resembled a huddle of hen and chicken huts in a small hedge-lined field, but these masked the entrance to a huge underground complex containing masses of rooms holding banks of teleprinters, telephone switchboards, Morse code stations and wireless telegraphy sections.

Iran’s Fajr satellite uses Ham Radio bands

Wednesday 4th February 2015

Nico Janssen PA0DLO reports that the Iranian Fajr satellite has an amateur radio band downlink on 437.538 MHz

On the AMSAT Bulletin Board Nico says that it carries a camera for Earth observations and should have a telemetry downlink on 437.538 MHz and a command uplink in the 144-146 MHz amateur radio band.

The Iranian satellite Fajr or ‘Dawn’ was launched on February 2, 2015 at 0850 UT from the Imam Khomeini Space Center which is south of Semnan in the northern part of the Dasht-e-Kavir desert.

The 50 kg satellite was carried on a Safir launcher into an initial orbit of 223 km by 470 km with an inclination of 55.5° and has been given an object ID of 2015-006A 40387.

It is Iran’s fourth satellite and has propulsion in the form of a cold gas thruster. Presumably the thruster will be used to circularize the orbit at around 470 km which may give it a lifetime of over a year.

Amateur Radio payloads share ride into space with Soil Moisture Monitoring satellite

Tuesday 3rd February 2015

Four NASA Educational Launch of Nanosatellites (ELaNA-X) CubeSats carrying Amateur Radio payloads launched successfully January 31 from California's Vandenberg Air Force Base.

The primary payload for the Delta II launcher was the Soil Moisture Active Passive (SMAP) satellite. SMAP's onboard radar will share Amateur Radio spectrum at 1.26 GHz. Amateur Radio is secondary on the 23 centimeter band, which covers 1240 to 1300 MHz.

"This is a good example of a compatible sharing partner," ARRL CEO David Sumner, K1ZZ, observed. "Any interference to amateur communication in the band will be brief as the satellite passes overhead."

SMAP and the four CubeSats all deployed successfully. The research CubeSats, launched on behalf of universities, will downlink their telemetry on the 70 centimeter band. The CubeSats and their downlink frequencies (modes) are:

Firebird II FU3 437.405 MHz (19k2 FSK)

Firebird I FU4 437.230 MHz (19k2 FSK)

GRIFEX 437.485 MHz (9k6 FSK)

ExoCube (CP-10) 437.270 MHz (9k6 FSK)

The GRIFEX satellite is a University of Michigan project, in cooperation with JPL, while ExoCube (CP-10) is a space weather satellite developed by the California Polytechnic State University-San Luis Obispo and the University of Wisconsin in partnership with NASA, and sponsored by the National Science Foundation.

The FIREBIRD program is a collaborative CubeSat space weather mission of two CubeSats designed and developed by Montana State University, the University of New Hampshire, The Aerospace Corporation, and Los Alamos National Laboratories - the FIREBIRD consortium. The FIREBIRD mission also is funded by the NSF.

SMAP carries a "synthetic aperture radar." The L band (1.26 GHz) radar is designed to measure backscatter off the Earth's surface.

The amount of backscatter returned to the radar changes with the amount of moisture in the soil. RF pulses at this frequency are less affected by weather or by a moderate vegetation cover.

The satellite is at approximately 425 miles up in a near-polar, sun-synchronous orbit. SMAP also includes a radiometer operating at
1.41 GHz to measure naturally occurring RF energy given off by Earth's surface.

Ofcom varies mobile operators' licences to improve coverage

Tuesday 3rd February 2015

Ofcom has varied the licences of the UK’s four mobile network operators to improve mobile coverage across the country.

This follows an agreement reached between the Government and EE, O2, Three and Vodafone in December 2014 to increase mobile coverage.

The licence variations commit the four operators to provide voice coverage across 90% of the UK’s landmass by the end of 2017.

In light of these variations, Ofcom will shortly consult further on the annual licence fees for the 900 MHz and 1800 MHz spectrum bands.

The Government directed Ofcom in 2010 to revise these fees to reflect full market value after the completion of the 4G auction. The two bands are used for 2G and 3G, including voice calls, and some 4G services.

Improving mobile coverage

Helping to improve mobile coverage and quality of service are important objectives for Ofcom.

Ofcom continues to make progress on its plan to help improve coverage in the UK and provide consumers with reliable information, such as maps, on mobile reception.

Ofcom published research on both mobile voice quality of service and mobile broadband speeds in 2014 and will publish further research on mobile data this spring.

This kind of research is designed to support consumers in choosing a service that best suits their needs, while helping promote competition between mobile operators on service quality.

Separately, Ofcom is working with Government on its £150m mobile infrastructure project, which is funding mobile phone masts in uncovered areas.

K1N Navassa Island DXpedition

Sunday 1st February 2015

Navassa: We're on the way!

As you know, our plan was to begin helicopter trips this morning as soon as USFWS gave us the go-ahead. We hoped to get in as many as three trips in today.

Because of the presence of a congressional delegation in Guantanamo Bay, Cuba, air services prevented the first of the two Navassa-bound USFWS helicopter flights to take off until 1830z. The first flight carried three of the six USFWS personnel, so the helicopter had to return to Guantanamo Bay and return with the remaining three USFWS people. It's about an hour each way so all of the above equals delay.

We received the call at 1830z with the OK to start our trips. Our first flight left a few minutes later at 1900z and should land about 2030z. It's a two-hour round trip between Jamaica and Navassa so we won't get but one flight completed today.

The first flight contained infrastructure materials and three K1N operators: George N4GRN, Glenn WØGJ and Jerry WB9Z.

Flights will resume at first light tomorrow and we should get most of the material and men ashore tomorrow (Feb 1st). Building the camp will be time-consuming and labor-intensive but we hope be able to get one or two stations on the air tomorrow evening. It will be another day or so before we're fully operational on all bands.

Because of the weather issues encountered this week by our supply vessel "Electra", we decided offload all the MREs, gasoline and water in Jamaica and transport it all via helicopter. More trips, more $$ but in the interest of safety.

Sunday 1st February 2015

Stephen Gulyas has been fabricating the absolute best BNC-to-SMA antenna adapters for several years. These are not 'one size fits all' adapters: Stephen realizes that to protect your handheld radio's delicate SMA connector the adapter must 'mate' solidly to the case of the radio..

He has just updated his offerings - now covering more than 50 HT models.

And the reasonable price has remained the same for as long as I can remember.

If you swap antennas a lot.. or otherwise connect/disconnect antenna/ cables a lot, then you need one of these adapters. Otherwise, budget for a $45-75 antenna jack replacement repair job down the line.. (grin)

Radio Sweden's SW and MW transmitters

Sunday 1st February 2015

A few days ago, I discovered a very interesting documentary video that gives a look at the Radio Sweden shortwave transmitters at Hörby, and the Sölvesborg AM transmitter. Håkan Widenstedt, was the Chief Engineer for Radio Sweden when this film was shot in 2006.

What is interesting about this video is the detailed view of the inside of the shortwave and mediumwave transmitters, and it offers some insight into the day-to-day work of an engineer for a large international broadcaster. In it's day, Radio Sweden was a much loved and popular station, and even today is sadly missed.

The film is in memory of Håkan, who passed away in 2011.
It is 30 minutes long and was filmed and produced by Kelly Lindman. The conversation is in Swedish with English subtitles. Special thanks to Jan Oosterveen for making this available for all of us to enjoy.
