Ive managed to separate all the transistors from all what I aquired yesterday, all that remains is to actually sort through them and put them away in the appropriate containers. At the moment they are cluttering up my antistatic mat somewhat
Despite that, I managed finally to get somewhere with the 10m WSPR beacon transceiver. Now having the right parts, including a few from yesterdays haul, ive managed to complete the build of the 14MHz Local Oscillator. Surprisingly, theres a lot going on on that little Colpitts circuit! With the two output capacitors in place, plus the bypass and decoupling capacitors, its rather a tight little circuit. Powered up, working first time, and showing 14.055MHz, a little tweek of the trimmer capacitor and its now dead on 14.0623Mhz as required for doubling to 10m.
Apart from a few more bench tests on the receive converter, measuring FM SINAD etc, ive done nothing further on the 4m transverter. I might tomorrow rig up an antenna and let it listen on the band for a while, see if I can find anything off-air, whilst I get on with some of the jobs Julie has left for me nearby in the garden.
