[R-390] Little calibration problem

[Tom M.]

Gil:

Sounds like you have a bad xtal in the osc deck if you only have this problem
on one band.

I think there is a 14 Mhz crystal which controls the 11 Mhz band.

Sorry but the only way to check is to swap out the xtal and see.  If you like I
can dig up a crystal for you to try.

I had this problem on a 51J-3.
