Hi all.
Also the SWR, i.e. RTX RF final stage load, would afflict the Pout/ALC
behaviour, that's on MY ICOM and YAESU RTXes (at least all at 90 without
any ALC sign and SWR <1.5:1).
Gary try the same setup with a dummy load instead of any aerial, with
and without your antenna tuner in line, RF filters or any other
lines/aerials accessories that is feasible. Try to separate each thing
sequentially, note before and after, seek for changes, try other modes,
programs, interfaces ...
What you wrote will make sense in any case of a RF output stage not
properly loaded.
Or, you could have a case of severe RFI thus just increasing a bit the
BF signal it will make that much feedback that, in turn, overload any
RTX ...
But there are other variables to be considered, a lot. I.E. too much for
a short email.

PS what I write here apply only partially to K3, that's another tale.

Gary -- I've work on a dozens of rigs...probably including all the ones you
have.
If you are unable to get at least 90W with no ALC then something in your audio
path is incorrect.
I'd like to work with you and ensure that either my directions need updating or
your settings need updating.
Did you follow the procedure in the document I sent?? That has worked on every
rig/audio combo I've tested which is over 300 operators now.
Can you call me an we can hook up and figure this out?? Gotta' make sure the
info I'm putting out is as inclusive as possible.

Absolutely. I own six different Icom HF rigs. All of them put out minuscule power unless there is a significant deflection on the ALC meter. The no ALC warning does NOT apply to all rigs. I agree with RTFM. You cannot go wrong.
