Hi Adrian Help me understand why the need to use 4FSK compared to say FSK OR BPSK ? For voice at 700bps there are few bandwidth issues for amateurs...
The multi level modulation (4FSK) will be inferior to others (without an time delay equaliser) when the long delay multipath is severe.... The long delay multipath tolerance I think should be above all other concerns. Or maybe I have "the wrong end of the stick " 73 -glen On 14/09/2017 8:28 AM, Adrian Musceac wrote: > Hi Glen, > > We don't need to use the same chain for digital demodulation, since we > are not software constrained.
