Once upon a time, I tried replacing the audio filter in a Triton IV with an
MFJ DSP filter. It didn't work due to excessive delay. That analog filter
should work. Maybe an Autec QF1 would be a good choice to try but the output
impedance would need to be transformed up in Z to match the input of the
Triton's final af amp.
