[RTTY] MMTTY difficulties

[Lee Roberts]

You are right. I didn't think that would have solved my problem since the 
button implies that one is using a USB device. After selecting the appropriate 
option I was able to send all of the macro. Combine that with eliminating the 
diddle problem and having to reverse the transmitted RTTY in the TS2000 I was 
up and running. But, I still have to figure out the "problem" with not being 
able to get the crosshair pattern in MMTTY. I had to use my experience and a 
little guessing as to where to tune my radio instead. I played with filters and 
other settings but couldn't get the crosshair pattern - it was more like an X 
pattern but the lines weren't at right angles to each other and the X was 
tilted (if you know what I mean). I couldn't get the X lines to be at right 
angles. Sometimes I had a pattern where one of the lines was wiggly instead of 
straight. As a matter of fact, playing with the filter options didn't help much 
in cleaning up signals, IMHO. I'm not sure if this setup is a major 
improvement over using the Kam+ but at least the Kam will be useful as a 
backup since it works with N1MM without the MMTTY. I suppose in a lab the 
N1MM/MMTTY setup would outperform the N1MM/Kam setup.

Thanks for everyones help.
