All posts for this thread are 6 years old. So was wondering what others set the TX filter settings for RTTY that are tight and work?

    400hz typically down to 250hz in a crowded contest band. Rock solid filter skirts on all of the 6K series radios. Using N1MM+ and MMTTY decodes quite well. de Clay N9IO

    If you happened to watch W0YK at contest U, he recommends a 500hz filter for the best RTTY decode.  I usually use 400hz (I have won several rtty contests)   Filters set at the tightest setting can result in additional latency.. so experiment with that and find your tolerance vs rejection level

    So by pushing the TX button (mic/cw speed,etc) In the filter skirts, you'd set 1000 plus or minus say 750 (the shift is 700 in afsk)

    Tnx Chris

    I did watch his Ed's excellent presentation. But I'm not interested in the RX filter settings, but what to set the filters (using a 1275 Mark ) by pushing the TX (mic/cw) button which brings up the TX window on the 6600M

    I wasn't clear on that I guess
