When I removed it from storage, communication was gone. It took a very long
while to lock, but did so and maintained lock for a couple of weeks before
going into holdover. It then locked back for a while.
I definitely need to do more trouble shooting on it before I give up
completely. It was the best unit I have. I also have a couple of
Thunderbolts, but I don't consider them in the same class as the Z3801.
I see Z3801s for sale on eBay, but I am reluctant to buy one. They are at
an age where things are going to fail. Also, for my needs, a Thunderbolt
would suffice. I just like the Z3801 better and would really like to get it
