Since we are talking about DSP (Digital Signal Processing)
that reminds me.
I was the first one to come up with it when I shunted the
r/t relay to ground on my HW-101 to get rid of the static
on 80 MTRS, so they all have to pay me royalties now.
Since Diodes are considered as digital devices and I
shunted the receive side to ground with a germanium diode
so the static crashes would go to ground.
At least .3v and above anyway.
Guess that was Pre-IF DSP.
Worked pretty good too bad I didn't patent it Hi Hi
73 fer nw,

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
