How does pak-125r work? Does it use the same varicode? Does it have error
correcting code like QPSK-125? How many phases does it use? Would it work
well for EME?

Tony,
Thank you for taking the time to perform the tests.
My anecdotal evidence is at odd with these results.
So the only way I add value to this discussion is to perform the field test in
a more controlled way.
Thanks again and best 73s,
John

Gary,
Thank you for the feedback. Using ARQ systems like you did we have also noticed
that faster PSK modes show better performance as in less repeat request than
slower ones.
Your first theory is the one we believe is the most likely contributor for the
ARQ links in general benefiting from
are more obvious than others. Hellschreiber is the only
mode I know of that can visually indicate this sort of thing, but that's
not an option with PSKMail.
Hope to hear from you soon John.

is to join the pskmail list here
http://www.freelists.org/archive/pskmail and send an email to request a sked.
Having an operator in front of the server for the first time is of great help.

Hi Sven,
I can only report on one implementation years ago with a Tandy TRS-80 which
processor probably had about the same power as an entry level MCU of today.
The detection circuit was an analog PLL with a pair of passive filters at the
front. It worked reasonably well, with good sensitivity
Hi Tony,
Thank you for the simulation results. I will report any field results for PSKR
modes in NVIS conditions.

John

That is realy nice path test. Can you try few other modes,
some more wide like ALE and Q15X25 ?
We experimenting a lot with PSK250/500, with or without

point about using RSID for beaconing is of
value and will be looked at.

Hi Gang,
All this talk about PSKMail piqued my interest, so last night I
installed the PSKMail java client.

Agree with Simon, great cross platform program, great new mode.
But I think PSKmail should also get a mention for the expansion of
it's network in Europe and North America, in particular due to the
persistence of it's author (Rein in Particular).

at least as implemented in fldigi. Not sure if it is the
permanent FEC but is seems quite robust in my tests between VK and ZL.
Have you had any comments or request for implementation in your
software or is it just too new, or not different enough?

calibration differences? My guest is that in the least category we
should find the psk and ifsk (e.g. Domino) modes and in the most
sensitive category MFSK modes. Is that a correct assesment?
Thanks, John (VK2ETA)
I had the same problem, that is deleted the .fldigi folder and it
didn't run (in fact it launched, but exited after a couple of second
without any message).
It took me some time to realise that the Hamlib library needs to be
updated to version 1.2.6 for fldigi 2.X to work. (see
