[1000mp] Mark V Audio Filtering

[Thomas Giella KN4LF]

I have a new Mark V Field. I do allot of digital mode operating and find the
selection of my stock 500 hz CW filter in the "data" mode under "APF"
to be very helpful.

However I still use my Timewave DSP-9+ unit for even more flexibility. I'm
able to narrow an incoming signal down to 100 hz when working PSK31 and 400
hz when working RTTY.

Sending a 100 hz AF signal to my soundcard is a much better way to go then
slamming it with a 2400-2800 hz AF signal and improves copy for me!
