[Kenwood] TS-940 birdies

[K8JRM]

Hello,

 

My Kenwood TS-940SAT went in for repair.  When it returned, it seemed to work well except for one annoying problem.  Although I can live with it, it bugs the heck out of me.  The problem is that my 940 has an S-9+ birdie every 100 kHz, regardless of band tuned!

 

I don't know what repairs were actually done.  I do know that I paid for a new synthesizer board and an alignment!

 

Is there something I can do to reduce this birdie problem without making things worse?  Although I have nearly fifty years experience with vacuum tube technology, the TS-940 scares the tar out of me!

 

BTW:  I don't want to return the transceiver back to the repairman in Florida who did the repairs!

 

Thanks for your assistance,
