[RTTY] LMS Notch filter

[Harry Coates]

I've been using the LMS Notch filter for years.. It makes a great quasi TwinPeakFilter.. Work with the Settings and Show fearure untill you get a  - 60 to -70 db notch.. Set the NOT button ON and move the little red marker to the center of the Mark and Space displays on the waterfall screen.. In my case that is 2210 hz, using the standard settings..
