Hi Rick, I did a brief side by side comparison with vbdigi and mixw a couple of months ago. The only MFSK mode in that version was MFSK16. The vbdigi program copied much deeper into the mud than mixw. There was quite a bit of static involved then. The newer version (fldigi V3) has improved

I have NO clue about this but... Simon Brown shared some interesting findings about his experience in programming Olivia in to DM780. Some of the existing applications that have Olivia in them did not entirely implement Olivia in a manner than Simon thought was consistent with Pavel's original s

It would also be very interesting to see if the improved MFSK modes in fldigi works better than in other software, especially when affected by lightning static. My informal tests seemed to suggest not much difference, however, if there was any difference, it might suggest that Multipsk was ever

Hello Tony, About Multipsk, could you first (if not done) the MT63 sampling calibration by clicking on "Sampling freq." and start the automatic calibration. Note: in Multipsk there is a double correction: * determination of the sampling frequency offset between the TX and the RX sound cards. Th

All, There seems to be some difference between Mutlipsk, MixW and IZ8BLY's software when it comes to decoding MT63. I ran all three programs simultaneously with a path simulator in line and the SNR set above the decode threshold. The results were the same whether I ran the programs one at a t
