Re: [Elecraft] CW station calling an RTTY station: use mark or space frequency?
Wayne, MultiPSK is testing a Reed-Solomon based mode identifier using a key-codeword and parallel decoding. When the program is in auto mode, it will detect and automatically switch modes.Then you would just have to send a special CW character sequence and the receiving program would switch to CW mode.I don't know if CW is one of the modes but I will ask the author, Patrick FC6TE.Other digimode programs are exploring this as well.

Re: [Elecraft] CW station calling an RTTY station: use mark or space frequency?
I'm going from memory dating back many years, but I think RTTY stations normally ID in cw by sending cw with the "key down" on the space frequency, and key up on mark. Sticking with that convention might make it a little easier to copy for them due to familiarity of the tones. I'm not sure too may ops would recognize what you're doing, but it would be fun to find out.
