Re: {Collins} SSB tuning question



The only band that I checked when recently recalibrating was 20m.  I believe
that I was <100 cycles low.

How far off are you when you switch bands... unfortunately can't do much
about aging crystals if too far off other than replace them.

While we are on the subject, how do you calibrate your frequency using WWV
and a 75S3-B?  This has become quite a challenge for me.  I know that it is
a simple process, but after I think that I am right on at 15 Mc., I go back
to 20 meters and am slightly off.

I have to admit this always confuses me as well listening on a USB/LSB only
radio like the S-Lines.  When you zero-beat to 15 Mz the S-line dial is on
carrier frequency and if you look at the S-meter the signal power peaks off
the side of 15 Mhz by a few Kc corresponding to which sideband the radio is
selected.  In a fully modulated AM signal the sidebands carry 4x the power
of the carrier and this is easily demonstrated on the S-line meter during
the zero-beat tuning.

The dial reading is where the suppressed carrier is.  It will be on the low
side when running USB and on the high side when running LSB.

I have what should be an easy question, but it has really been confusing
me. If I have a SSB station tuned in so it sounds correct and the dial on my
75S3 reads 14.200, then does this mean that the stations suppressed carrier
is at 14.200 or does this mean that his USB is centered (approximately) at
14.200 (and his suppressed carrier is at 14.198 or there abouts).
