[R-390] 3 MHZ issue

[rbethman]

Steve,

I'd look at the crystals.  The 3Mc crystal "may" be either flaky, OR the 
socket and pins are cruddy.

I'd also look at the trimmer for THAT crystal.

Those would be the first things I'd look at.  After that, the switch 
position for 3 Mc, on the Mc switch may be dirty, and need to be cleaned.

Just a few ideas.
