Note Copied from WIA Facebook Page Clarification re Use of AX prefix: There has been some unhelpful statements made by a splinter AR group re a proposal to use the AX prefix for commemoration of the recent death of Queen Elizabeth II. These statements have caused much confusion and if the proposal is followed then it will result in radio amateurs operating illegally and risking prosecution. The regulations regarding the use of the AX prefix remain unchanged and DO NOT allow for legal use on this occasion. Whilst it is a significant and solemn occasion, worthy of appropriate commemoration, ACMAs formal advice on this matter is very clear that is NOT LEGAL to use the AX prefix on this occasion at this time - irrespective of whether it is a major or minor breach.

Two Dashboards For CQ-UK YCS235 http://ycs235.xreflector.net/ycs/ CQ-UK DMR Master https://dmr.cq-uk.uk/

Isabella, pictured with her father Matthew, said her chat with an astronaut was 'amazing' An eight-year-old girl from Kent used her father's amateur radio equipment to chat to an astronaut aboard the International Space Station (ISS). Isabella, from Broadstairs, spoke to American Kjell Lindgren for about 45 seconds as the ISS passed overhead. Dr Lindgren said the conversation "may be my favourite so far". Isabella said it was "amazing", adding: "Once he found out I was eight, his voice instantly turned from normal to joyful." During their chat, which he tweeted to his 67,000 followers, fellow amateur radio fan Dr Lindgren told Isabella "it's so great to chat with you, thank you for getting on the radio and saying hello". Afterwards, Isabella said she had been inspired by the encounter, saying it proved that "boys and girls can be whatever they want". Her father Matthew, who has held an amateur radio licence for more than 15 years, found out the ISS was passing overhead from fellow ham radio enthusiasts. He said: "You have to get the right time when the space station is passing overhead, and it has to be the right time of day when the astronaut is using the equipment. "I was a little bit jealous that it wasn't me talking to him. But it was amazing seeing Isabella having that contact." Kjell Lindgren described the conversation with Isabella as "may be my favourite so far" Isabella's parents said their daughter has long held an interest in space and ham radio, and they are encouraging her to apply for an amateur radio licence. Anyone who wants to operate as a radio amateur in the UK must hold a licence issued by Ofcom or qualify under international arrangements. Ofcom issues three levels of amateur radio licences - foundation, intermediate and full. To qualify for each licence, applicants must pass an exam at each corresponding level.

Thanks to Richard McKee Facebook : Baluns, ununs and Tuners. Gang, "ALL TOROIDS ARE NOT CREATED ALIKE"! Just because it's a toroid doesn't make it right for the job at hand. There are many different materials used for the many different applications. You must match the material and size of toroid to the frequency range, power level, and job you want it to perform. You can simply just pick out a "TOROID" from a bargain basement supplier and expect it to work. So, before you pay out your hard-earned cash, make sure you are getting what you need in the first place and it will save you a lot of frustration! The one pictured below is a mix 2, powdered iron core for example - not a ferrite core. But I see folks all the time trying to make baluns, ununs, chokes, and transformers with them, only to find out it doesn't work like they thought it should. Powdered iron cores are fine for use as inductors in tuned circuits such as low pass filters and such, but not for the reasons mentioned above - at least not for HF purposes. Anyway, do some research, ask questions, and research some more before buying toroid's and do it right the first time.
