[Elecraft] Freq calibaration

Mon May 5 10:33:01 2003

I think (and I could be wrong) that you might have problems in LSB and USB
trying to zero beat if your SSB filter settings aren't wide enough to cover the
lower (audio?) frequency range... but that's only a guess. I believe I may have
my SSB filter wide enough to actually sense zero beating on both sides of the
carrier when in either USB or LSB - but that may be because I set my default
filter for 2.4 kHz and shifted it down quite a bit lower so that in
Spectrograph it appears to cover nearly 0.0-2.5kHz.
