Well, despite not thinking I'd have time to correct my K2 raspy audio
until after the holidays, I managed to squeeze in a little time early
this morning and here's what I discovered:
1) There is probably nothing wrong with the K2 or the KSB2 board, as
far as wiring is concerned.
2) Don (W3FPR) asked me a few questions, MOST of which I answered "yes"
to. For example, my LSB and USB did sound similar (but raspy). The
carrier was balanced well. The two things I DIDN'T do were adjusting
the LSB and USB BF1 values for best transmitted signal quality. I guess
those little check boxes next to the instructions are important after
all (hi). The one remaining question I have is the following:
The instructions for optimizing the BFOs say you can move the BFO as
much as +/- 200 Hz from the frequencies in Table 3. Moving them about
100 Hz removed the raspiness, but I had to move them about 350 Hz total
before I considered the signal optimum. Is this setting OK or should I
back down to around 200 Hz?
Thanks to all for the suggestions on this little problem and 73's,
John AA0VE
