Sure enough, power down and ant disconnect were key.

That sounds like the 1024 week rollover problem.
I don't have a 3805, but I had similar troubles with a 3801.
The 3801 has a command to set the date. You can find the details in the
manual which is readily available. You may have to set the date before it
gets the date from a satellite. That may be easier if you disconnect the
antenna and then power cycle.
These are my opinions. I hate spam.
