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.
