I guess I'll just dump the rig and buy a Ten Tec Orion.  But maybe I'll =
visit their reflector first and see what there owners are writing about.

Hi  John:

I guess I am going to regret forever making the 1% SWAG.=20

Oh well, maybe we will really solve this riddle this time. In spite of =
my 1%
statement, I do sort of worry that 'my time may come' and I will be the =
guy
writing about experiencing 'sticky relays, etc".

John, I guess the good news is that you have a hard failure, the Service
Manuals are "in the mail", and you are a very competent 'techie'.=20

I will look for the next chapter in the "sticky relay saga".
