Re: How to assemble an Collins filter + Board for FT-817/857 and save $$$!!!
|
I have an FT857D that has a DSP filter. It will go down to 60 Hz width. I will tune in a CW signal at a much wider bandwidth, then narrow it down to 120 or 60 Hz if need be. Very useful. I wish the FT817ND had it.

I use a 300 Hz Collins filter in my FT817 and also other rigs with IF DSP with adjustable filters for CW.? I often use a 1.4kHz filter for tuning.

What other filters exist for the 817/818 rigs?
Looking at INRAD's old page I see a couple of options, though they are long gone.
CW: 300 and 500Hz
SSB: 2000, 2300, 2500, 2900KHz
I thought there was a narrower CW filter out there somewhere, but maybe I'm thinking of a different rig.? I thought there was a 100Hz option.
