My original system for a Multi Mode Beacon with WSPR is achieved in the simplest manner possible i.e.. the addition of just one more tone to MEPT_JT coding.
This give the possibility of S/MT Hellschreiber in a very narrow bandwidth. The Hell has a squashed appearance for sure and could be improved.
QRSS3 Morse takes some time to send, Dashes being 3 times longer than a Dot, have 3 times longer to be effected by QSB, broken up and their information wasted.
There is another system, using equal length characters for both, Castle Mode, this can require up to 12 Tones. Hence I gave thought to perhaps re using the tones in the same character. My new system, Step Mode does this. Using luck my call sign can be represented with 5 tones. I have implemented this. There are plans afoot for a full Morse Character system using 7 tones.
