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. T

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

I run with the AGC off, and the audio limiter set carefully... I control gain via the RF gain control. If a strong station pops on, I use the notch, if a really decent DX station is calling me, I narrow the filters to show just that station... I can operate with a station one mile away, runn

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

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,
