Alright, a little bit of an update on my problem... Gary at Elecraft gave me a list of voltages to check upon TX.
Unfortunately, my scope is old and I couldn't get it to play fair, so the only thing I could really measure were DC voltages with my VOM. I'll probably go ahead and start putting the RF probe together sine my scope seems tired. Anyhow, I checked R50, it's right on, good, not open. I checked D7, it has 7.95VDC on it's anode and 7.32VDC on it's cathode. I checked Q6, and it has 1.0VDC on it's base I checked Q6, and it has 12.2V on it's collector (at TX) R67 and R68 continue to bother me, they both read 195 ohms, even when measuring directly across them. I don't see why that would be given the schematic, but they are the correct color code for the given resistors, and when I measure I have nothing connected to the antenna jack. I have a sneaking suspicion it's a problem with a toroid lead, but I have checked and rechecked them all, measuring continuity across windings at the solder pads. Do any of you guys offer troubleshooting service, in person? :) Thanks for any ideas, Jeff On Wed, Jan 31, 2007 at 11:58:28PM -0500, Jeff Kinzli wrote: > Oh, and I have checked, and C167 is indeed installed. :) > > On Wed, Jan 31, 2007 at 11:45:54PM -0500, Jeff Kinzli wrote: > > So, I'm finally getting to the transmitter alignment section on K2 #5945. > > > > With a dummy load, I set power on 40M to 2W, and go into tune mode.
