Mike Dixon G3PFR - SK
Fri 19th March 2010Mike Dixon G3PFR, a giant of the amateur radio microwave scene in the UK, passed away unexpectedly on the evening of Wednesday March 17. Mike had been a key figure in UK amateur microwave circles for many years. He was chairman and secretary of the RSGB Microwave Committee at various times until the late 1990s when he became the RSGB Microwave Spectrum Manager a post he held until December 2006. In this latter role, he represented the interests of microwave operators at meetings with the IARU, RA (later Ofcom) and WARC. He dedicated himself entirely and unselfishly over this long period to promoting the interests of all UK microwave operators, often to the detriment of his own spare time pursuits. |

Installing transceivers in vehicles
Thur 18th March 2010FCS1362 is the UK code of practice for the installation of mobile radio equipment in land-based vehicles. It replaced the old MPT 1362 and points out that the power supply cable should only be fused in the positive power line with the fuse located as close as possible to the battery of power source. This appears to be a change from MPT 1362 which suggested installing fuses in both positive and negative power lines.

Radio Sweden ends Medium and Short Wave
Thur 18th March 2010Radio Sweden will terminate its medium and short wave broadcasts this October 31st in favour of web services - with Swedish Radio management stating that is the best use of resources and in line with international trends. The English-language service is to continue on the web and on national broadcasts. The Russian output will be available on the web, as is the German now. Among the immigrant languages, Albanian, Assyrian-Syriac and Bosnian-Serbian-Croatian are to be terminated on the same date. Meanwhile, Arabic and Somali - the largest immigrant language groups here at present - are to be boosted. The same applies to Romani - one of Sweden's five official minority languages. The Persian service is to include even Dari spoken by the rapidly increasing number of Afghan refugees coming to Sweden. Kurdish broadcasts remain unchanged. Swedish Radio's output in immigrant languages will be available on the web and broadcast nationally. |

Ofcom smears 3G across spectrum !
Sun 14th March 2010900, 1800MHz approval expected in August It was reported this week in the Register, that Ofcom has finally proposed the use of 3G technologies at 2G frequencies, slipping the amendment into a bundle of updates and tweaks that is expected to get approval come August. This has been included in the bundle mentioned in the previous article (Consultation on Licence Exemption changes). and will also permit the deployment of 3G networking technology at the 900MHz and 1800MHz bands which were previously restricted to 2G (GSM) operations. But one shouldn't expect to see 3G spreading immediately as there's neither the infrastructure nor the handsets to support that just yet. Read the full article in the Register by Bill Ray :- |

Cable operators fear interference from radio network
Fri 12th March 2010The Deutscher Amateur Radio Club (DARC) reports on the legal action that a cable operator took about the proposed auction of 800 MHz for wireless networks. The Cologne Administrative Court rejected the action brought by Kabel Baden-Wuerttemberg saying that if the cable operator was afraid of interference they could take action to improve their cable system. For years cable operators have claimed their networks are "tight" and there could be no problem with cable interference to radio bands despite the fact that the audio channel of one station has disrupted the Amateur Radio use of 145.750 MHz for many years. The DARC views the ruling positively since it will encourage cable operators to upgrade leaky cable systems. As well as stopping the pick up of any 800 MHz transmissions it should also reduce the interference that leaky cable systems cause to Radio Amateurs.

Canadian Surfacewave HF Radar
Thur 11th March 2010It is reported that Raytheon Canada are requesting Federal Government funding to develop transmitter technology to cut the possibility of its HF Sufacewave radar interfering with emergency locator signals or ham radio signals. The report in the Ontario newspaper The Record indicates that the existing system is a one-kilowatt output prototype and there are plans to produce a four-kilowatt output prototype by the end of April and eventually develop a full-scale 16-kilowatt system.

Canadian Amateur Radio access to 137 Khz
Thur 11th March 2010Industry Canada has approved access by Canadian radio amateurs to the Low Frequency (LF) band 135.7 - 137.8 kHz, subject to certain conditions. The Revised Canadian Table of Frequency Allocations, promulgated in December 2009 to incorporate changes arising from decisions taken at World Radiocommunication Conference (WRC) 2007, permits amateur radio use on a Secondary basis subject to Footnote 5.67A. The Footnote states: "Stations in the amateur service using frequencies in the band 135.7-137.8 kHz shall not exceed a maximum radiated power of 1 W (EIRP) and shall not cause harmful interference to stations of the radionavigation service operating in countries listed in No. 5.67. (WRC-07)". Industry Canada has advised that Canadian radio amateurs may now use the band and that Schedule I of RBR-4 Standards for the Operation of Stations in the Amateur Radio Service will be amended in due course.

Hard drive evolution could hit Microsoft XP users
|
Tue 9th March 2010 Hard drives are about to undergo one of the biggest format shifts in 30 years. By early 2011 all hard drives will use an "advanced format" that changes how they go about saving the data people store on them. The move to the advanced format will make it easier for hard drive makers to produce bigger drives that use less power and are more reliable. However, it might mean problems for Windows XP users who swap an old drive for one using the changed format. Read the full story on the BBC Website :- |

Trapping sunlight with silicon nanowires
Mon 8th March 2010Researchers with the Lawrence Berkeley National Laboratory are developing a new approach that could substantially reduce the cost of solar power. "Through the fabrication of thin films from ordered arrays of vertical silicon nanowires, we've been able to increase the light-trapping in our solar cells by a factor of 73," says chemist Peidong Yang, who led this research. "Since the fabrication technique behind this extraordinary light-trapping enhancement is a relatively simple and scalable aqueous chemistry process, we believe our approach represents an economically viable path toward high-efficiency, low-cost thin-film solar cells."

Ham radio satellite survives 'close encounter'
Mon 8th March 2010AMSAT-NA VP Operations, Drew KO4MA, received notification from the US Joint Space Operations Center, located at Vandenberg Air Force Base, California on Sunday, February 28 warning that amateur radio satellite AO-51 would have a close approach to another satellite, FORMOSAT 3-D, on Monday at 1056 UTC. This occurred over the Eastern US, with many stations on hand capable of receiving telemetry from AO-51 before and after the near miss. Drew said, "The predicted miss distance was 953 meters, which is over 3000 feet overall but the radial difference between the two orbits was only 39 meters." Steve, W3HF noted, "Given the orbital uncertanties of both satellites, an orbit separated by only 39 meters could mean that distance may become eaten up rather quickly!" In preparation for the close encounter, Drew shut off the S band tran- smitter and turned on the digital downlink at 2 watts, with telemetry transmitted every 5 seconds. The next morning, on March 1, Drew was able to post a message that AO-51 was alive and well, "It looks like we are fine. A second warning email this morning from the Air Force called it even closer, but everything was working at LOS this pass." FORMOSAT-3 is a constellation of satellites launched on April 15, 2006. It is a joint U.S.-Taiwanese project with major participants including the University Corporation for Atmospheric Research (UCAR), the National Science Foundation, the Naval Research Laboratory (NRL), the Air Force Research Laboratory (AFRL) on the U.S. side and the National Space Organization (NSPO) on the Taiwanese side.

Video of 2m D-STAR DV Access Point Dongle
Wed 3rd March 2010A YouTube video shows the new 2m D-STAR DV Access Point (DVAP) Dongle at the Vienna Wireless Society Winterfest on Sunday. The new DVAP product allows Amateur Radio operators to walk away from the computer and transmit/receive D-STAR voice and data using a two meter D-STAR radio. The DVAP is basically a Gaussian Minimum Shift Keying (GMSK) modem with a two meter transceiver built in. It has a maximum power output of about 10 dBm (or 10 milliwatts) which gives the unit a range of about 100 metres using the included SMA based antenna.
