HF Packet is also sensitive about the baud rate, 300 baud Packet won't decode if you are set up for 1200 or 9600 baud. Note that no difficulty was experienced in decoding from the recording at the proper aud rate, despite some obvious signal fading. >From my QSO at the southern tip of Texas, I

With the capability to cut and paste a received message from MT-63 and send it out via Winlink, the 10 second turn around is very close to simultaneous operation. If you want to make things difficult for your self, or discourage others from using the available transport layers, you can advocate h

Charles, I think HF packet is a useful mode, but I can tell you that it does fall short in terms of sensitivity compared to many others. More importantly, path simulations and on-air testing show that it doesn't take much in the way of HF channel distortion to cause throughput issues with 300

Hi Charles, The latest version of MultiPSK has AX25 using PSK 250 (or PSK 63) modulation. I would be interested to see whether PSK 250 is any better or worse than FSK 300. 73 Sholto K7TMG Charles Brabham wrote: > > > > > > - Original Message - > *From:* Tony
