Stop, you're breakin' my heart!
I've got 2.8, 2.1, 1.0, -- , .250 in the main RX
and 2.7, -- , -- , .50, -- in the Sub. ('--' = no filter)
I chose .250 8 pole, thinking it was .250 wide (Inrad's usually pretty
good), and I'm about to install a .400 that I bought at last year's sale.
I'm used to a nice tight .250 - helps quite a bit with the noise (city
lot). Hopping back and forth between the .400 and .250 with XFIL will
fulfil most of my needs. What I'd like is a .500 and a .250 (real
bandwidth, both 8 pole).
I find that I almost never use the 1.0.
I like to use DigiPan for a visual display of what my filters are really
doing for me. Being mostly a CW type, a 1.8 on SSB is too narrow for my taste.
Even the 2.1 needs a tweak of the SHIFT so I can stand it.
>Matched filters are important for diversity...
I'm enjoying diversity on 160 with my current filters, relying on the DSP
for additional selectivity. I don't feel that I need matched filters (yet).
I may eventually change my mind.
