Hi I build a K1 (80m, 20m) during the last days and had a lot of fun! The manual is just awesome and I am looking forward to make my first qso with it.
Now I have a problem with the tramitter. That is why I joined this list and I was very glad to see, that there is much activity. The rx alignment went well and the resistance and voltage checks of the tx part are all fine. When I first started the tune mode on 80m with 2 watts, it shows me somewhat like 1.7, Q7 became quite hot and something started smelling. I was not able to read the current consumption before I disconnected the source. After double-checking all resistor values, the orientation of all diodes and ICs and the transformers, I tried it again. But now, regardless on what Out-Pwr and Band I choose, the display shows "P0.1" in tune mode. I can hear a very weak tone in the K3 standing next to the K1. The current consumption is at about: 60mA rx, 200mA tx I cant see any cold solder connections nor bridges. So I guess I burned Q7 somehow. Any idea what I can do or what went wrong here? How can I test a 2SC1969 and what do I have to check, to make sure, I don't just burn a new one? Many tnx fer ur help and best 73 de Lorenz / HB9TYU (Zurich, Switzerland) -- Lorenz Koestler <lor...@koestler.ch> / HB9TYU PingMe: https://pingen.com/*lorenz ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
