OK Paul, try this. Connect a second antenna to the "RX ANT" jack, and
switch to receiving on a separate jack. Turn the transmitter power down
low, and then key it and see if the problem still exists when using the RX
ANT.

I could have been more clear on that
There is no linear connected and when it comes back weak it is the whole
receiver chain S meter is lower too. Like there was an attenuator cutting in
and out. The attenuator is off.
The other problem at turn on---maybe the tubes haven't warmed up hihi. I'm
an OT and more at home with those.
