Thanks for all the replies, both on and off list.
I should have given my satellite background in my first email; it would
have saved some of you quite a bit of typing! :-)
I'm an AMSAT Ambassador, AMSAT-NA Life Member, and my very first satellite
QSO was on AO-13 in 1993 (but then I was inactive on the birds for 20
years) - and did learn a few things I didn't know at Hamvention's AMSAT
Academy. :-)? I have given "Satellite 101" talks to about 10 clubs in the
past 2 years,? have manned info tables at a few hamfests, and may tackle a
couple of hamfest forums solo during the next year.
I had hoped my question about receive versus transmit was specific enough
(since I know how to operate the birds and explain doppler when I give
presentations at clubs), but as I said, it would have been helpful to you
respondents if you had already been familiar with my background. Perhaps I
could have worded it better, and been more succinct. I'm glad that I got so
many answers - and I did get a comprehensible, clear, answer right off the
bat - and hopefully your responses will help those who just "lurk" on the
BB to understand doppler better and how to work the sats more effectively.
So thanks again to all who replied!

On linear transponder satellites
(https://www.amsat.org/two-way-satellites/), you _can_ hear other
stations doubling.
AM is wasteful of power, as others have commented, and has no place on a
power-limited satellite. The carrier, containing no information,
consumes 2/3rds of the transmitted power. The rest of the power is split
between two sidebands carrying the exact same information.
(https://www.tutorialspoint.com/analog_communication/analog_communication_ampl
itude_modulation.htm)
I disagree strongly with your assertion that FM was "nearly impossible"
to generate. (https://en.wikipedia.org/wiki/Armstrong_phase_modulator)

I showed a quick slide with the Doppler equation on it ... that delta-lambda
stuff. Then I told them pretty much what you said ... and I could hear a

...and of course there is no reason NOT to adjust the lower frequency
especially if it is computer controlled. It's just that lower frequencies
do not change as much for a given satellite speed (see JoAnne's Doppler
equation to determine why :-). And as someone said, the FM capture effect
makes it even less important.

I will be driving to Newport OR tomorrow June 7th and will try to stop for
AO-91 in CN86 (maybe CN85 depending on traffic) at 13:12 local 2012 UTC.
I will stop in Newport CN74 over night and on Saturday June 8th and I will
try AO-91 at 11:57 local 1857 UTC and then AO-92 at 12:08 1908 UTC.??? This
all depends on how the swap meet is going, cause I'm selling.
Friday evening I will be at Yaquina Head Light USA-907 for those who also do
lights.????? Most likely I be around 14.335 KHz.??

Ham-Com hamcom.org is being held in Plano, TX, on 7-8 June where AMSAT will
have a booth.
Several of us will also be doing satellite demonstrations from the hamfest
in EM13.
Listen for us (AA5PK, AE5PH, W5PFG and possibly others) on most of the FM
and linear birds from 1700Z until 2000Z on Friday
and 1345Z until 2030Z on Saturday.

Mark, N8MH and I did some testing tonight on AO-85 as it is almost back in
full sun. The transmitter and COR repeater came on, but not the
telemetry/IHU. Repeater sounded good but stayed keyed without an uplink
signal. We shut the transmitter back off since that was an unexpected state.
We'll do some more testing tomorrow.

AO-85 was commanded on again about 1200Z this morning. Repeater is on, but
so far no DUV telemetry, so IHU must not be working. Also, repeater isn't
dropping between uplinks as it should in this mode. We left it on, feel free
to use while you can. Reports too please!

We'll do some more testing tomorrow.
