The HT-32 has no BPF in the classic sense.? Just some L/C type
providing a pretty gentle roll off.?

The Drake TR-4 came with 2.1 kHz filters.? I replaced them in mine
with the aftermarket Inrad 2.5kHz filters.
Not only do I get much better reports on the air but the receive
fidelity is a LOT easier to listen to!
I get great audio reports with my HT-32B.? I think it's got a 3kHz
filter in it?
I couldn't find the filter specs in the SR-400 manual.? I guess
they really don't say what the BW? is. but it would seem to be
somewhere around 2.3-2.5 kHz based on the shift in the carrier
frequencies?? I guess the only way to know for sure would be to
"sweep" it.
