The TX Factor team are celebrating an important milestone with the release of the 25th Episode of the only UK TV show dedicated to amateur radio. In this packed episode Bob G0FGX gets the authoritative lowdown on the new Elecraft K4 Transceiver from one of the team behind it, Eric Swartz, WA6HHQ. Mike G1IAR tackles the subject that Brits like discussing the most, the weather! He finds out about the WQ Weather Radar by Weatherquest, the company founded by TV Meteorologist and radio amateur Jim Bacon, G3YLA. With recent severe weather events in the UK and around the world we are reminded of how easily the infrastructure of our 21st century communications could be taken offline. There are also many other possible threats to the power grid, the internet and mobile networks that could pose a problem for emergency communications using repeaters that rely on those technologies. Mike and Bob took a trip to Southampton and Portsmouth to meet a team of radio amateurs who are working with their local emergency planning officer to make their repeaters resilient by using point to point rf links utilising off the shelf kit and they demonstrate how easily other repeater groups could adopt the same ideas. DMR is now a widely used amateur radio mode, but one downside is the dreaded code-plug! The RFinder B1 is a rig that offers a world without code plugs or repeater lists and Bob talks to the guys that designed it. No episode would be complete without the free to enter draw and there is a bumper prize pack to celebrate the 25th edition. TX Factor is proudly sponsored by Martin Lynch and Sons and the RSGB.
