Anyone have experience with / tested MFSK 4/8/etc? Tried a QSO with XIQ using MFSK4, despite decent signals both ways, no print. Does MFSK take reasonably good SNRs to decode? Perhaps we were running opposite sidebands.... Any insight into what might be expected or capable is appreciated. Software was Fldigi. 73 Eric NO3M / WG2XJM
