[1000mp] MK-V RTTY Filter Selection

[Jim W7RY]

AFSK is fine as long as you WATCH your microphone gain and make sure the 
processer is OFF!

I  unfortunately was next to someone that was REALLY SPLATTERING over 1 KHz 
on 15 meters during the RTTY Roundup a couple of weeks ago.

I really recommend FSK if at all possible!
