Yes I did skip a few minor revs. But I think that a sigificant change requires a significant notification.
You may have been aware that the MFSK-8 modem code in all revisions of gmfsk, both the original and the gmfsk-hkj variant was broken. That broken code found its way into fldigi. Fldigi could communicate with any other fldigi or gmfsk or vice versa. But not with the rest of the digital modem world. Specifically not with IZ8BLY's Stream or with MultiPsk both of which could transmit and receive on MFSK-8 and 16.
The broken algorithm has been discovered and fixed. I bench tested both MFSK-16 and MFSK-8 against both of the Windows applications and it works perfectly. I have been staring at that code for about 4 months and this morning experienced a Eureka !
Also went back and took a hard look at the way the AFC was being worked in both gmfsk and fldigi. Fldigi has a new AFC mechanism that works like a champ.
Both of these fixes will be retrofitted to gmfsk-hkj in the very near future.
Also tested fldigi for proper CR/LF recognition when receiving signals from Windows apps. I think that works as one would expect now. You need to tell me if it does not.
