PSKMail uses PSK125 ot PSK63 so it does not use ARQ.
Pskmail uses arq on top of psk125.

I guess, from my point of view, PSK mail won't really take off until it is
written for windows as well as Linnux.

I have to agree with John on this. When you have 90%+ using MS OS's,
some old ones and some newer and some very new, the other OS's struggle
to compete, and that means Apple and Linux. And my recent posting on
the HFDEC group outlined some of my difficulties with trying the QEMU,

If I recall this pskmail is a ARQ type program with
a TX RX timing close to Amtor and Pactor. If this is
correct, will it still work with this timing? The last
time a Amtor type linux program come out it could
not do any better then 37.6% of what a TNC did
running side by side.

The timing is completely different. Pactor sends 1 block at the time,
pskmail bundles 8 blocks in a frame, resulting in a lot less turnaround.
Block length is adaptive and changes with channel quality.
Amtor was 45 Bd ARQ. Pskmail is 125 Bd ARQ.

So rather then getting a small block rejected you now have
a muck bigger one trashed. I fail to see why it is so much better.

Hi Walt,
Winlink2000 does not have an HF sound card implementation. They are
possibly working on it, but it has been 2 and 1/2 years since they
stopped further development on SCAMP (Sound Card Amateur Messaging
Protocol) when they discovered that it would not be possible to get it
to work
