[600MRG] FT Question Answered?

[Frank Lotito]

I may have answered my question - We use AFSK not direct FSK to generate modulation modes such as FT8.  AFSK as I recall requires "linearity" in the audio processing stages.  But once in the RF domain we can use non-linear devices, such as heterodyne converters, Class E amps, etc.  Did I get that correct?  73 Frank K3DZ  / WH2XHA
