Re: Ic-706 ptt not working #WSJTX_config

HISTORY TIME: Back in the 1980s when the IC706 radio was being designed, high-speed digital packet networks used 9600 baud DFM on 2M or UHF. It was similar to how some hams still send RTTY signals using FSK DC voltage levels into the radio instead of analog AFSK tones.
Just, if somebody wants to know the modern usage of the same method for DRM (Digital Mobile Radio). This time a four level frequency modulation.
