Re: K1 no output on 20 - KFL1-4 problem?

[kl7r]

Very interesting Greg,

I can hear some signal on 20 but weak.


Sounds like we have identical problems,

I wonder what could have caused 20 to go out?
 
The K1 was on the shelf for a couple of months and was
working fine when I put it up.  I dont think I did
anything dumb to cause it to stop working.

It is interesting that others have seen identical symptoms.
I'm going to take a few DC voltage measurements and see what I see.
