[Icom] Filtering at 9 MHz vs. 455 kHz

[Jeff Kilgore]

I used INRAD 400-Hz filters in the 8.83-MHz and 455-kHz IFs in my Kenwood
TS-850 (I recently sold it). This worked very well for CW and data modes.
Before this, I had used a Kenwood 500-Hz filter in the 8.83-MHz IF, which
helped a lot and worked well, but the dual INRAD filters were quite a bit
better.

Obligatory ICOM content: I sold the TS-850 because I bought an IC-756ProII.
Great rig!
