At a hamfest a week ago there were two k2s for sale from an estate. I bought one and a friend (not on here yet) bought the other. His receiver is dead. The transmitter has full output (110 watts) on all bands. The receiver ... AF gain works, side tone works, filters work, and RF gain works. This can be heard in the change of the pitch/volume of the noise emitted. ATTN and Preamp do not work/function. We see no codes. We made a cursory disassembly and unseated and reseated all the boards. It has the 160 meter option in, and we bypassed it. Unfortunately I sold my old signal generator at the hamfest in anticipation of getting a more up-to-date unit. Hmmm mabe use my old Model 59 GDO as a generator. We are thinking relay ... haven't yet gone into it that far. One thing that puzzles me is the RF gain control (R4). Where is it in the circuit? I see it connected to J1. I see it coming off of P1 and that is it where it ends!!?? I see R5, R6, R7, etc but I can't find where R4 connects? I am thinking a relay somewhere in there? loose jumper or plug I have overlooked? Maybe someone can throw me a bone as to a hint as to where to look for the missing RF to the receiver. Many Thanks, Mike WA5POK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
