[TenTec] Orion PLL Problem

[Ed lawson]

Confess to general lack of knowledge regarding Orion so perhaps
question obvious.  I have a chance to buy an Orion at an attractive
price, but owner says it has a problem of losing PLL lock.  Turning rig
off and then on fixes problem for awhile and then it will happen again.

Is this a problem that has at least a set of probable causes and
diagnosing and fixing can be done with a reasonable investment of time
and money?  Or is this one of those problems that may be
unfixable and may lead to it becoming a brick?
