[R-390] R390A weak rf gain

Ray,

We need more information. Hope you have a copy of the Y2K manual, revision
3. 

The "rf gain switch": I can only think of a RF gain potentiometer. It is a
reverse log taper potentiometer, value 5K.

"e607": You have me stumped. Any number starting with 6 is in the AF
section. 

Regard,
Craig
