Tim AFSK will outperform serial port FSK at the receive end of the link. No doubt about it because Windows is not and never will be a real time operating system. Windows internal timing causes the tr

Robert Yes I have measured it and timing jitter is a real problem using windows to key a COM port line. The logging software has nothing to do with it. EXTFSK and others which include 2Tone make use

I have migrated to the TinyFSK implementation to avoid the Windows timing irregularities that David summarizes here. This is similar to the CW mode where a WinKey or other external hardware keyer is

Yes I have measured it and timing jitter is a real problem using The "timing jitter" is only an issue when using software generated FSK (e.g., EXTFSK or "Software FSK"). If one uses the serial port i

Joe and Ed Yep TinyFSK does an excellent job, which is why I made a bespoke driver within 2Tone for it. In testing TinyFSk I found no detectable timing jitter. I looked at programming a PC connected

Working on this myself. It's on the same shelf where all the other partly-finished projects go to die. But I have the Arduino (in a socket to cut down on exposing my poor soldering) at least. :-) Los

I looked at programming a PC connected UART, but all the specifications I looked at for current stock are incapable of doing 45.45 they do 45 if they can go that slow. The way to get a PC connected U

A very interesting discussion, but so far only Windows has been mentioned. Does anyone know if Linux or Mac or DOS for that matter, has the same problem? 73, Bill W6WRT -- This email has been checked

Joe, I have a Kenwood TS-2000X; I have looked that list over 5 times and do not see it. The radio is so bad they did not want to put it on the list???? 73, David AD4TJ In addition to TinyFSK, the mic

Psst.... don't tell them that a narrower transmitted signal is easier for the other end to copy too, Ed. I.e., you will be asked for fewer repeats. Practically all (well perhaps not MMTTY) RTTY demo
