They recommend turning agc off and manually adjusting RF gain.

I believe at least some of the DSP filters in the K3 are FIR (Finite
Impulse Response) ones, which should be phase linear. The roofing
filters will not be phase linear, so I would think you could get away
with using a narrow DSP filter, as long as you used a relatively wide
roofing filter.

I find FT8 more works better with strong, nearby signals and a
wide bandwidth. I have only once or twice narrowed the bandwidth
from 4K Hz because of a strong signal outside the FT8 subband.
Otherwise, reducing the RF gain has fixed things for me.
BTW - If I'm trying to copy a very strong FT8
ut I may want at that
time to review advice given in this thread by you and others.

Weak Signal work on 160m is very different than a band that is wide
open. The key here is clean signals not being over driven. The amount
of power being used is not the issue it is how poorly a transmitted
signal is.
The vast majority do not understand this concept and think FT8 is a QRP
mod
Using 1500 watts on a digital mode (except for RTTY) is unwarranted a
bad practice. I've been using the new digital modes since PSK31
started. I was on the bleeding edge of working with PSK in its earliest
days. This is the first time I've heard anyone try to justify using

Carl,
Not sure about the KPA1500 but I believe the limit on the KPA500 is
90C. It is normal for the fan to come on and speed up automatically at
particular temperatures. I set up some of the macro buttons in the
KPA500 utility for various fan speeds. If I run a high duty cycle
digital mode,
I recommend reading the manual, looking at the Facebook page etc and looking at
what Joe Taylor and the other developers say about using the waterfall to
determine signal strength and signal quality.
Hint, waterfall signal look overpowered, wide, etc? Turn down receiver RF
gain.

I see we are about to enter the dead horse beating ceremony over FT8 power

I suspect that most guys who feel it’s just fine and dandy to squirt legal
limit FT8 signals all over the place have never been on the other end of that
kind of inconsideration. Maybe if they saw how it virtually blots out
