Just finished building and aligning sn 05834. Have a couple of questions:
1 - Preamp...I wonder if anyone else has noticed a very noisy K2
preamp...with no antenna or just dummy load connected, when I turn on
the preamp there is a marked increase in noise output.. Is this normal
or do I have a problem?
2 - I aligned the filters with spectrogram....is there any way of
getting the bfo set so that the received signal is the same pitch on all
4 filters? and, does the pitch change when switching filters affect the
transmit frequency?
Thanks for any input
