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
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.

PSK63F is within the STREAM download? I saw references to it in
the reference documentation, but it's unclear to me if it is actually in
the application you download.

Yep, it is there under
Hello Phil,
According to my measures (under gaussian noise), PSKFEC31 has a minimum S/N of
-14.5 dB (2.5 dB better than PSK63F) but the speed is twice weaker (28 wpm).
It includes a FEC system (bit based) which permits to have a more robust mode
than PSK31 (about 5 times less errors than
Patrick,
Thank you for the information.
If throughput is one the metrics for this comparision then I clearly see
your point.
The argument of reduced character set in PSKFEC31 is a little difficult as
it looked like Tony was not considering that particular metric as his
comparsion include RTTY
Ok Many thanks
Have re named com port's and the system is working ... new problem has
shown up HRD will communicate via the usb comm port with the
ft-897-d ... but I now fine that fldigi and wspr will not . dh !
Tnx- G ..
--- In digitalradio@yahoogroups.com,
HRD will communicate FLDIGI and WSPR will 'not' via same port
(not at the same time of course)
Odd problem has occured using a USB to Serial cable for the FT-897-D
HRD will communicate normally and control the rig ..
BUT
Fldigi and Wspr .. now will not communicate
