Well, after getting some connectors and a gas tube arc protector on the antenna, I'm back on air. Thanks to KX9X roaming today to confirm I'm functional.
Now, receiving the ballot is still in the future. Looks like the USPS is really slowing the delivery of the mail due to no OT, and other orders from the top. Hope I don't need to ask for a replacement due to their lack of funds.

What's the difference between the two? I am a Amsat member (as of sunday)
and only have access to launch.amsat.org's login. I have not found a way
to register for amsat.org's login and my launch.amsat.org login does not
work on amsat.org.

During the next election cycle for Board of Directors I hope these guys will run - they are both senior and vibrant contributors to the community.
1) Bob Bruninga (WB4APR) - APRS on RS0ISS + many satellites
2) Frank Bauer (KA3HDO) - ARISS liaison to AMSAT
This is just my personal opinion - I am not sponsored by anyone; no sideways hidden agendas.

Anybody else hear this on the 16:00z pass of AO-92 that is finishing up
right now? Or is it my SDR? (didn't hear it on the AO-91 pass immediate
before this AO-92 pass).

And here's a short text from Ian, GM3SEK about adjusting preamp gain. No
test equipment needed. Too much gain can be a bad thing...
====
Here's a method that requires no test equipment at all. It comes from
G4DGU, who designed all the original muTek transverters and outboard
preamps to have adjustable gain. This method uses the sharp threshold
effect of FM detectors at low S/N ratios, and it allows you to optimize
the preamp/transverter gain for your local band noise conditions.
1. Turn the transverter/preamp gain well up.
2. Find a very weak but steady unmodulated carrier (off-air, not from a
signal generator or a local birdie). Rotate the antenna until you can
just detect the signal in FM mode.
3. Reduce the preamp/transverter gain until you hear the noise increase.
The FM threshold is sensitive to a small fraction of a dB in S/N.
4. Increase the gain just a little,to the point where you can't hear the
quieting improve much.
5. Switch back to a real DX mode.
Remember that every dB of unnecessary preamp/transverter gain will
probably subtract almost 1dB from your system intermod intercept!
The penalty of adjusting the gain correctly is that you're living just
above the "knee" where S/N will begin to deteriorate rapidly if
something changes. It's worthwhile to repeat this test every few months
- especially just before a contest.
