With Tony's permission, PSK63F data is added to the graphs at

Why not bite the bullet and use PSK125R and pskmail client-to-client arq.
It adds an interleaver, is less susceptible to doppler effects
and adds full duplex arq at

Demonstrating a suite of digital coding methods are vulnerable to Doppler
spread does not tell the whole story. What does the signal look like on the a
spectrogram when subjected to Doppler spread? Yes, you have incomplete or
scrambled text, but t

Very interesting. What about PSKFEC31 under the same test scenarios?
Certainly, there would be more a in throughput, but that is a matter of some
liberal use of CW shorthand.

All,
Recent path simulation tests indicate that Nino Porcino's PSK63F offers
better performance over PSK31 and PSK63 in a couple of areas. The most
significant improvement is it's ability to endure Doppler spread found on
paths that cross the polar ionosphere. Both PSK31 and PSK63 fail miserabl
