[Elecraft] 50MHz TX Problem

[Gregg W6IZT]

I have the 50 MHz problem and have a KAT3. I haven't done enough testing but
I suspect that the problem with the relay opening may be in the KAT3.

Has anyone had this problem who doesn't have a KAT3 installed?  I don't mean

a KAT3 bypassed, but no KAT3 at all.  The reason I'm asking is that there 
have been a few folks (myself included) who would suddenly experience a 
sudden high SWR, and after that would wind up with a residual SWR on some 
bands even with the KAT3 bypassed.  This sudden high SWR occurance happened 
to me on 20 and 30 meter CW.  I could go back and retune the KAT3, but the 
antenna SWR had not changed (according to my in-line PowerMaster), and then 
I had residual SWR on 17-10 meters that was high enough that I couldn't 
properly set up my cal'd 5W/50W power on those bands.  The only soution was 
to replace the KAT3.  And since having my new KAT3, I experienced this once 
(again operating CW on 20 meters), but the residual SWR cleared and I 
haven't had the problem recently.  I wonder if there is something lurking in

the KAT3?

So I thought it would be interesting to find out if only the folks having 
the 6-meter problem have a KAT3.
