I bypassed the tuner relays, but makes no difference. I left the one turn link in ckt.
I thought maybe maybe the tuner being in place was affecting the drive rf into the output xistor,
but it looks like the same rf drive on the scope with the tuner in or out...but not the same output rf because the
rf into the tuner does just what the rf does on the output of the tuner...drifts down to a smaller level.
Baffled...

Oh and the ATU is in the CAL (bypass) mode. Of course it is in the TUN mode
for the testing of inserting different L and C elements and noting SWR
changes to see that all the elements are working.
