Transceiver TS 870 SAT
Has anyone ever experienced a  drifting problem with  the 20 mhz reference
xtal oscillator  outside
the adjustable range ?

Are there any service bullitens to address this problem?

Are there any temperature compensating circuits in the  unit to control 20
mhz xtal oscillator that
could fail causing the xtal drifting off frequency?

Any suggestions or ideas on this problem would be appreciated
