Hello Demis,

you may want to try reseating the DR7 first. I would say that EXACTLY 2 
MHz offset indicate a digital problem. The relevant circuitry sits on 
the DR7. The connector is on the upper left when the front looks to you, 
9 Pins. If you have an intermittent there, it could cause the problem 
you described. A little bit of Deoxit may help prevent further contact 
issues.


As always... whenever there is something strange happening on a TR7 or 
R7, reseat the boards first before you do any alignment.

Hi All,
I've problem with my R7A, this morning during a QSO at 14,222, the
reception frequency jumped directly to 12,222 for a few seconds to
return
to 14,222. I tried to rotate the band switch, the up and down
buttons, but
occasionally the frequency jumps. Where's the problem?

Do you have a solution to this problem?

Many thanks for possible help.

My best 73's

Hello Demis,

Guess the PLL needs adjustment, check the procedure in the service
manual. I had something similar in my TR7 which was solved that way.
