Hi Rud.
The decoding delay is minimal and probably not even noticeable, even
in chat
mode.
The decoding delay will not be an issue in chat mode. But it is
annoying for someone interesting in DXes or just high rate of QSOs. It
will take too long to just decode call sign during CQ to find out
FWIW http://psk.gladstonefamily.net/cgi-bin/pskstats.pl
(see also http://psk.gladstonefamily.net/pskmap.html )
Well over 25,000 distinct callsigns seen on PSK over the last three months.
I doubt anything will overtake PSK in popularity in this decade.

A new protocol with all of PSK31's current virtues augmented by
error correction and the ability to convey modest-sized files in real-
time would initiate a similar transition, I suspect.
BTW, PSK63F has error correction, but I never heard it on air. FEC
will always introduce decoding delay.

Ok I'll jump in on this one just once.
I feel if such ARQ modes as Amtor or Pactor 1, 2 or 3
could be done via sound card. Most modes would be dead
by noon tomorrow.
But since they can't no need to go on.
Some will never know what they are missing.

We have several modes that fall in to that category. Or, in one case,
did have with SCAMP which has not been made available after it was
developed. While it did not have the fall back position of the Pactor
modes, the developer chose not to add more robust modes. The speed was
quite good,
Its more likely that they know exactly what they are missing -- but
don't believe its worth the extra cost to obtain it.
Furthermore, there are still quite a few KAMs and PK232s around; the
incremental cost to their owners of running Pactor 1 would be very
low -- and yet this mode is not
I am daring to post my opinion after reading the previous ones on this
thread.
In general, ARQ modes can insure the delivery of almost 100% correct
transfers. FEC can do nearly alike, but since there is no feedback,
transfers may get corrupted as SNR drops. ARQ + FEC can achieve a lower

Found it. Look here: http://mmhamsoft.amateur-radio.ca/
It was the MMSTV software that auto-decodes the SSTV signal. By auto-
decode, I mean it determines the proper protocol for you (Scotty 1,
etc.)

Hey Jeff - your neighbor K7NHB here.
Don't give up on SSTV. One of the software packages I use - not MixW -
automatically determines the correct SSTV mode. Or, you can pick the
Scotty mode and be correct 90% of the time.
Once it stops snowing in Bend, I'll get real antennas in the air (both

This remains an open challenge, not a closed book. Skip KH6TY's
latest work seems promising...
