Check first the trimmer capacitor which adjusts reference crystal
oscillator (Local unit), it may be dirty, rotate it back and forth
several times, if it stabilizes then you can use it a few more time, if
not you must change it. After this you must also re-calibrate your
frequency display.
Good luck
