That is exactly right, with the fully computer controlled setup I can move
the downlink (RX) up and down the pass band looking for callers and not have
to touch the TX frequency as it is managed by the software and can hear my
own voice with a steady tone quite well.

Umesh,
If you can tune around and always hear your own downlink on the correct

Good Morning All,

If the rate of Doppler change was different based on your physical location
(for example, you are at AOS when the other station is at TCA) then unless
the computer adjusts for the change in rate of the shift, I could see how
the two stations are drifting...

Just my guess: If you?re tuning so that you sound good to yourself, you may
sound a little high (or low) to someone else. Also, since most people
you?re operating don?t know what you sound like in person (James Earle Jones
or Pee Wee Hermon).
You can check your tuning by sending a tone and zero-bearing with the
received tone.
Or experiment with adjusting your received signal so that you?re a little
low (or high) with what sounds best to you. Then see if you?re still
chasing each other up (or down) the band.

Devin, I assumed that was not the case because the calling station's tone
did not change between CQs or during the transmission, but only changed
AFTER I had responded.

Hi Ron, I'm also a big fan of "frequency at the satellite" and it is one of
the main reasons for using total computer control while working SSB sats.?
In fact, I can move the RX across the pass band and not have to worry about
the uplink, it is always spot-on.?
So my guess was that if both stations were computer controlled, they could
be synced-up throughout the pass.? However, as I'm learning here, there are
more variables than meet the eye.? Learning is part of the fun !
Incidentally, often times I hear two stations rag-chewing throughoutt the
pass.? I hear them both steadily but one sounds slightly higher/lower.?
Since they remain steady but I hear them differently, there must be much
more going on here... (btw, I have worked HF so I understand when I am not
zero-beat on the calling station's frequency)
Since you mentioned it, I have great respect for mobile stations operating
SSB sats, it surely requires a great degree of dexterity and finesse. I
guess I can never attempt that.
Appreciate the feedback.

Umesh,
A question and comment on your statement:
> (b) Sometimes I hear a station calling CQ and it remains on the same
> frequency during successive CQs,
The method SatPC32 and HRD and others employ is keeping the ?frequency at
the satellite? a constant, varying your uplink and downlink frequencies as
appropriate. In your statement above, do you mean by ?on the same frequency?
that you need not change your SatPC32 controlled frequency to remain tuned
in to the CQing station? If so, then both of you are tuning to keep the
?frequency at the satellite? a constant. This method is the preferred method
of tuning for base stations. Mobile stations may not be able to do it. By
keeping ?frequency at the satellite? a constant, QSO?s with many
participants can converse as easily as though they were on 20m.

Umesh,
If you can tune around and always hear your own downlink on the correct
frequency, then you are doing everything right.

Hi Drew, I ended up doing just that, even though I thought we could stay
synced for the QSO.? After full computer control, I rarely have to touch the
radio dials.? But thanks for your suggestion.

Just my guess:? If you?re tuning so that you sound good to yourself, you may
sound a little high (or low) to someone else.? Also, since most people
you?re operating don?t know what you sound like in person (James Earle Jones
or Pee Wee Hermon).?
You can check your tuning by sending a tone and zero-bearing with the
received tone.?
Or experiment with adjusting your received signal so that you?re a little
low (or high) with what sounds best to you.? Then see if you?re still
chasing each other up (or down) the band.
