K3: A funny thing happened

[Phil Salas]

"I was on 30m cw, swr about 1.1 when suddenly I noticed my output drop from
100W to about 40W and the swr had risen to 4 or so."

Do you have a KAT3 installed?  Doesn't matter if it was bypassed or not.
Several of us have had similar problems.  In my case, this occurred on 20
meters, and then again on 30 meters.  And while the SWR wound up recovering
OK on those bands, I wound up with a residual SWR on 17-10 meters that would
not go away - and I only resolved this by having the KAT3 replaced.

I bring this up each time someone reports something similar, as I believe
there is something here that needs to be addressed.

No, I don't have the KAT3 installed, but it sounds as if it might be the
same sort of thing.

Thanks anyway, perhaps it won't happen again!

Forgot one thing about the 30m VSWR situation:

While the ATU was trying to tune the antenna, it started at something
like 25-1.  It got down to about 6-1 after quite a bit of noise, but all
during this time my external wattmeter indicated zero power output.  On
all the other bands, it shows a low power while tuning.  It also
produced no power when I keyed it after tuning.

And you are sure the antenna and coax connections are O.K.?????
