Since I have now constructed a K1 and a K2, I can say that setting
the K2 up for SSB is more involved than it might be for CW. To that
end, there needs to be another Elecraft test device, to assist people
to set up the K2. Most of what is needed is already present in
individual tools Elecraft makes as kits. We need an item that does
three(3) things:
1). A dummy load to handle at least 20-watts
2). A pad buffer (at the output of the dummy load) to be used to
filter out/reduce the transmitter RF, and detect/output the audio.
This is used as the input to a computer soundcard (for use with
Spectrogram or other spectrum analyzer)) for transmitter bandwidth/
BFO analysis.
3). A audio white-noise generator which is fed to a cable terminated
with a 8-pin mic-plug. This would be used to source the signal which
would be used by the entire transmission chain, finally outputting
signal which can be bandwidth and quality analyzed for proper
transmitter alignment.
Alignment of the receiver IF/BFO is much more straight-forward and
requires little more than a N-Gen (K2 audio output fed to computer
soundcard). But getting the transmitter aligned to the same point as
the receiver, and calibrating the voice response thru the SSB filter
is nothing less than hunt-&-peck for most of us (hope the best and
pray the fellow on the other end is forgiving <grin>).
This message should be taken as a formal request for Wayne and Gary,
and not as a huge new source of discussion. We all know this request
is reasonable and has utility.
