Good day, Ron!
Satellite 'Move-2' was west of your location around that time & is supposed
to have a beacon on 145.950. So, that's a possible source.

Hi Scott,
I tried to get an audio sample of the beacon, but no luck. After
spending some time downloading a few files (long, slow download)
identified as CW at the satnoggs site I had to give up, there was no
identifiable Morse on the ones I downloaded.
So I can't say that it wasn't Move II, the CW was at about 25wpm,
some longer dashes, it appeared to me to be random, definitely no
audible data.
Too bad I didn't record it.

Another plausible idea is that someone was practicing CW on 145.948 and you
happened to pick it up locally. Seems like an odd frequency to practice on
however it cannot be ruled out

Hi Brian,
I could wish that there was another CW operator within VHF range
here :-) The MOVE II satellite beacon sounds likely as there was
definitely Doppler (negative, it was moving away at 21:12) shift on
it. But I appreciate the helpful speculation.

Just to follow up on this, I pretty much took the antenna apart --
removed all of the phasing harnesses to make sure the connectors were
clean, dry, and free of corrosion. I also removed the aluminum
"blocks" and made sure the boom was clean underneath them, per the
suggestions here. When I replaced the harnesses, I was very careful to
arrange them precisely as shown in the assembly instructions (I had a
couple of them not quite right). Then, I put the antenna analyzer on
and messed with the matching sliders until I got the SWR down to 1.2:1
at 145.9 MHz. Quite an improvement!
Thank you for all of the suggestions -- especially regarding the dress
of the harnesses. I think that was the big one.
Unfortunately, when I put the antenna back on the roof, it still
receives like a dummy load. I think I must have a bad piece of coax.
That will be the next project.
See you on the birds (eventually).

Have you looked into something like the the NanoVNA as a diagnostic tool?

Very handy for only $50!

Before New Zealand went into COVID-19 lockdown, the folks at Rocket Lab
did a test to recover a first stage Electron rocket.
You can see the video here: https://www.youtube.com/watch?v=N3CWGDhkmbs
There are some other videos of the view from the rocket and inside the
helicopter.

Bob, your call has not burned itself into my memory, so I can neither
confirm nor deny if you are a poor operator; this is a good thing. There
are people on that list in my head. I can hear them saying their call in
their own voice... .. . . . . .
The repeat QSO's are annoying when there is a busy pass going on, but
sometimes it is easier to answer that call then to let them attempt it 3,
5, 8 more times; being a bit sarcastic here. However, on dead passes, once
the bird has left most of the country, I have had some awesome rapid fire
everyone-work-everyone-else round tables. QSOs are finished, the next one
happens, everyone waiting as needed, ... those feel so good, even if you
have those people in your log 10s, 100s of times.
I was excited to have my son call CQ and talk to a station on a linear bird
once. He loved to hear his own voice coming out of the radio. I do not
think I will be likely to try it on an FM bird anytime soon. Heck, doing a
demo on an FM bird on a weekend, good luck. Fortunately I am on the right
coast and can pick the coastal leaning pass, if possible, or at least early
pass which seem to be slightly possible to make a few QSO's on with 5-10w
of power.
