[Kenwood] TS940S Intermittent on 15m

[Dino Papas]

My venerable 20 year old 940 has developed a very annoying  
intermittent operation on 15m (yeah, today while I was working 3Y0X  
on 15m!!!).  The symptoms when they appear are constant, reduced  
keydown output in SSB mode.  For example, while talking into the mic  
the modulation disappears and I get a reduced carrier only signal  
out.  A few months ago I opened her up and applied DeOxit and  
reseated every connector I could physically get to.....being an  
intermittent makes it a little harder to figure out when you've fixed  
something but it "seemed" that the instances of impaired operation  
went away for a while but have now crept back in.

It's only on 15m....

Anyone else seen anything like this?  I can't take it over to Kenwood  
East unless it did it all the time....

Thanks in advance!

P.S.  I did threaten it by telling it I would call AES and order a  
new radio if it didn't start working right....it did and I did work  
Peter I Island....
