In the olden days, analog radios would use two IF filters and slide them back

some of the PBT you were referring to.
Being as technically adroit as your average cow pie, all of this is over my
head.
I have a TR7 sitting here that has something called PassBand tuning. I recall
that I used it, with one of those ancient, non-digital, I didn't build it Autek
filters.
I have memories of twisting many knobs to get rid of the crud, and either
notching out noise or peaking the signals that were down in the mud, even lower
than the bottom dwellers and scum suckers.
Given that I hardly ever, but maybe now and then operate SSB, and would like to
try other digital modes, what would suggest as a reasonable approach to filters?
Thanks
Thom, who finds ordering from a Chineese Menu easier than this filter
stuff...and only has first hand knowledge of leaky roofs, which he doesn't
believe is an official option for a K3.
