Yes. We had a 2 deg elevation and the satellite was about midway between
OZ7SAT and UA9UAZ over the Kola peninsula.

That sounds like a very plausible explanation.

Agree.

For what it is worth, here are the settings we use. You have to be
rather aggressive when connecting to a satellite, so the T1 timer is set
very low:

Window size: 1
T1: 0.5 sec
Retry count 10
Maximum packet length. 128

The latter is probably not necessary with HO-68, but it was with GO-32.
