[Elecraft] KPA-500 watt meter vs. Palstar

[Mike Fatchett W0MU]

Sounds like RF.  Are all the pl259's and other cabling tight etc?

We were having some strange problems with our Fire radio at the station 
and somehow the connector on the back was nearly off.  Screwing it back 
on solved a bunch of strange oddities that were happening in the comm room.

If I set the K3 for more than 80 watts the output of the K3 goes into oscillation evident on the K3 watt meter. Lower than 80 watts everything is OK. The TX gain calibration is good.
