Well,
With many thanks to both Greg and Fred, especially for the recipe re Jessie, I
have successfully built and run WSJT on Raspbian on the Pi!
I cranked up the over clocking to 1 Ghz and the performance even monitoring 20m
right now is surprisingly good! It takes the Pi until about 6 seconds into the
next time period to complete the decode operation but I do see successful
decodes.
Some more effort required to see how this works for anger but its built and
working.
Pretty amazing all the way around.
Thanks folks!

Hi Stu,
That's a much bigger issue, mostly likely a Kernel level / timer issue (Clock
--> Divider --> Timer(s) --> Application). I did find a few posts about
re-compiling jackd/jackd2 but I don't know enough about the Rpi to make any
solid recommendations here.
Best bet on this one is to post the issue on the Raspberry forms:

Thanks Greg,
I’m trying to do this to avoid dragging my laptop out for 10 Ghz roving – so
the band won’t be busy! I can always try over clocking to 1 Ghz and see what
difference that makes.
Right now I’ve got past the PIL problem by installing PILLOW instead – then I
ran into an error:
FATAL: cannot locate cpu Mhz in /proc/cpuinfo
Sigh… this is endless.

Hi Stu
We just had a discussion on this regarding WSPR, which uses most all of the
same packages that WSJT needs. Fred (WA1DLZ) posted his findings regarding the
requirements for Wheezy and Jessie (Raspian). The main issue (I think) is that
python3-pil is missing from Wheezy, but is present in Jessie.

You will still need to resolve the Audio setup as well as the WSJT.INI
settings. System resources may also be an issue, as the Rpi is has a much lower
powered CPU (Arm6 I believe it is) than a standard x86 CPU, but in theory, it
should be possible. I would think decoding would be slower on a busy band. You
may also want to look at Arm6 specific compiler flags.
Needless to say, using WSJT on an Rpi is not optimum, and will require a good
bit of special configuring, but it should be possible. How well it performs is
another matter entirely.

Sorry for this dumb question but I’m banging my head against the wall trying to
run wsjt for Rapsian on a Pi.
I pulled the top of trunk and built ok but when running, I get “No module named
PIL” - but PIL is installed and apparently now under Python3, its should be
import Image (but that doesn’t work either!).
So, can someone point me to a branch of Trunk that will build and run under
Linux or, should I be trying to build Wsjt-x instead?
Thanks!
