Never seen a HI RFI indication before ... could it have been HI RFL [hi
reflected]? If it's HI REFL, it sounds like something has failed in the
AL-811 input circuit.

I've had my K3 since around 2007 and recently have started getting a HI RFI
message on the LCD while operating CW and using my AL-811 amplifier at
about 500 W.
It seems odd since when I'm "key down" my antenna should not be connected
to the receiver.
I'm not using QSK. I have a bit of delay to keep the amplifier's T/R relay
from operating between characters.
I don't have a separate antenna connected.
I've run 100 W or QRP most of my ham life but for the past five or more
years I've occasionally used the AL-811 and had no issues until recently.
My antennas are a 134' EFHW inverted L and an 88' dipole fed with ladder
line via a Johnson Matchbox.
CW SS is coming up. I'd like to use the amp but worrying about my receiver
may be distracting.
Anyone seen this?
