For the first time I have been able to monitor the radio effects of a meteor shower. It was an interesting time with many pings from about 0400 onwards. The setup was far from ideal;an Icom 7200 as the RX using a long wire antenna resonated for 6m and Spectrum Lab on the PC. [...]

I have had a few discussions recently about SCA filters, switched capacitive audio filters,and how effective they are. The best way to demonstrate is by listening to recordings made with a variety of receivers. The first is a Small Wonder Lab Rockmite on 30m. The clicks/clunks are the sound of switching the filter in/out. This [...] I will listen,and listen,and then listen again before calling. I will only call if I can copy the DX station properly. I will not trust the DX cluster and will be sure of the DX station’s call sign before calling. I will not interfere with the DX station nor anyone calling and [...] During the last week there have been some good openings on 6m. I managed to work into Eastern Europe several times and heard stations much further afield. The only antenna I have is an HF long wire tuned up on 6m. It seems to have a good lobe to the SE. Six is often called [...] The RSGB news pages are carrying a clarification as to who is responsible for investigating interference to broadcast transmissions and amateur radio. The RSGB say: The position is that the BBC is now responsible for investigating interference affecting domestic TV &radio broadcast reception. [...] Ofcom remains responsible for investigating interference to the amateur service,[...] Like many others I donated what I consider to be a reasonable amount of money to the spectrum defence fund. I did that freely as I see the use of power line communication devices as a real threat to the HF spectrum. At first it looked as if the RSGB were making waves (excuse the [...] I have just finished building a Small Wonder Labs SW+ 20. Nothing spectacular in that but using it for QSOs yesterday took me back to my first brush with radio. Around 50+ years ago I discovered a box of crystal set parts in my grandfather’s shed. After much haggling I was allowed to have them. [...] It is about 50 years since I first started playing with radio. Driven by a fascination with stories of my grandfather’s crystal sets and the box of old looking components left in his shed. This was in the time of big valve wireless sets and long wire aerials to poles down the garden. Amateur radio [...] I recently discovered some photographs of one of my first /P events. The pictures were taken on 3 May 1972 at Burton Dasset hills in South Warwickshire. I think it was a 2m contest. The transmitter was cut from a Pye Cambridge with valves in the RF section and a transistorised modulator. It was supposed [...] There is news on the Ofcom web site that the NOV for 5mhz is to be extended to 30 June 2010. You will need to reapply for a new notice of variation,NOV,to your licence to operate on 5 mhz after June 30 2010. The application form is here. | ||
