Hi,

I have an old TS-850, it have been with me for over 10 years now.

Lately it have periodic low receiver sensitvity on 40m.
Signals seems to be att. atleast 20 to 40 db.
This happens when switching from tx to rx, sending a "DIT" or two restore
full sensitivity.

It can happend in 7 of 10 tx/rx switching.

Any suggestions?
