Don, I am not the original builder of the K2, so I will be downloading Spectrogram. I will go through the individual connection points for the swapped crystals and capacitors with the ohmmeter to make sure that there are no connection issues. Thanks for identifying a troubleshooting path!
I will advise on results. Thanks again! 73, Steve, N0CZV -----Original Message----- Steve, How does the OP1 filter passband look when viewed on Spectrogram? It should show a nice flat passband. If it has a dip or valley in it, look for a bad connection on one of the capacitors or crystals. What is the possibility that you damaged one of the thru-plated holes when removing the old crystals and capacitors. Use the schematic to determine 'which is connected to what' and check all those connections with your ohmmeter. You may also have a problem with T1 or T2 soldering or a poor solder connection in the switching diodes or R-Paks. Re-flow the solder in those areas with a hot (750 degF) soldering iron. 73, Don W3FPR On 2/10/2014 2:30 AM, Steve Garwood wrote: > Hello! > > I am working on a K2, <3000 s/n in which I installed the K2 SSBCAPKT along with the 14 crystal kit. > > Receive is working, audio level is low on the OP1 filter, normal on FL1, etc. > I have transmit, with good audio, however, no measurable power output or ALC reading. > > I've been searching for something similar to this, no luck so far..... > > It seems that the filter output is low, but functioning.....
