Dear Folks: I am the proud owner of K2-10 #6922 and, so far, have been operating it exclusively on cw (I am building the SSB option right now, though I am a brass pounder). It is a fine radio and has caused my TS-850S and AL-80 amp to gather a lot of dust.
My only problem has been the filter alignment. I have repeatedly tried to align the filters, and always seem to end up with a situation where the passband of the filters never falls within the passband of the receiver at its maximum bandwidth (I have it set for 150hz). In other words, the received signal, when the receiver is right on it, always seems to fall outside of the 70hz filter (if I tune the receiver to copy the received signal with the 70hz filter in use, and then switch to the 40 and 20hz filters, the signal stays within the bandwith). The last time I tried to align the filters, I used a noise generator and Spectrogram, and followed Tom Hammond's (N0SS) instructions. After doing this, I always need to turn on the RIT and turn a few hz below the received signal to bring it within the bandwith of the 70hz filter. What am I doing wrong? For reference purposes, I have my sidetone set for 600hz. Thanks and 73 de Bernie, KF0QS -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-Filter-Alignment-tp7567975.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
