[GreenKeys] Tri-tone RTTY

[Duncanancy]

Ron,I thought that the MD 522 had two sets of 85 hz shift, not 85 and 850 shift. Or is that another choice?73, Duncan K2OEQ Sent from my Kleinschmidt TT-4/TG, the US Army's first portable digital communications device, 1950-1980

There is a diversity front panel setting that adds 85 Hz shift to the 850 shift.  John K9WT and I have used it for a demonstration once. Ron BoltzK3TZJ
