G3YHV showing off some of his more unusual valves to 2E0GHT, G4OTJ and G8NT. Colin brought a couple of his construction projects. One being an SSB transmitter but with keypad entry of frequency and a PIC/DDS VFO (much to G4RIC’s horror as he is a bit of a purist when it comes to valve equipment).
Another was a 40/80m CW transmitter using some ancient valves, one dating from the 1920s.
