[Elecraft] K3: RTTY Question

[John Reilly]

I'm brand new to RTTY. I have MMTTY setup so it receives and transmits 
(AFSK) via VOX. I would like to do the NAQP/RTTY this weekend and use 
N1MM. How do I setup N1MM to key the K3?

Would anyone be willing to share their N1MM RTTY macros? I'm not sure 
whether RTTY requires a special key sequences (or just "John CO")? I 
noticed in the supplied MMTTY macros that most of them were preceded by 
"ryry" or some sequence.

Thanks a bunch. Any other RTTY advice would be greatly appreciated!
