Well, I got the other 2.8 KHz wide IF filter for the
6.3 MHz IF of my OMNI VI. Now I have a pair, one in
the main line for each IF. It sounds better than the pair
of 2.4's, and theoretically has better rejection a little
outside the normal passband. Wow, the PBT now works
just about right for me, centered and all. Wider for
SSB, narrower for CW, that's what I wanted....that's
why I have a couple of the INRAD filters in there now.
I have not looked inside the schematic yet, but has
anyone changed the audio rolloff characteristics to get
more sound from the OMNI? I would like to get a little
more lows, I think the highs are fine. I suspect the
audio chain would let a little more through from these
filters if I gave it a chance, hi. My Kenwood TS 850
with the cheap-o ceramic filter at 2.7 KHz width sounds
a LOT smoother than the OMNI, and I would like to get
a little closer.
Also, has anyone really worked over the 12 pole 2.4 KHz
filter yet? Does it perform well respecting the CW
waveform?
