Hi Joe and all,
WSPR 4.0 r4727 on ARM armv7l (SVN 4795)
I've adjusted the "limit" value to 4000, recompiled and have now run for
over 1/2 hour (just shed background noise) with no problems.
System: Banana Pi with Fedora 21 (Release Candidate 5) kernel 3.4.105.

I have added this to the required svn location for the Linux installer
to find it.

This is not a very useful statement. The decoder used in my WSPR code
uses the sequential Fano algorithm, and execution times vary widely
depending on input data. Signals well above th
Hi Allan,
I forgot to mention, try using WSPR0 ( command line version ), and see
the Decode Speed differences there. Bare in mind, it does not use CAT
control, send spots and all the fancy things WSPR GUI does, but, it is
very light weight.
You could easily write a Daemon to send spot information
Hi Alan,
I'm not surprised by this at all.
Try running some Single Core POV-Ray or MPEG encoding benchmarks and see
how it stacks up against, say, an Pentium-M class 1Ghz processor. Make
sure you have good cooling though.
Arm devices are great for many things, computational tasking is not one

Hi all,
Problem:
WSJT crashes when drawing "specJT" waterfall, even if window closed.
Solution:
Re-install PIL (Pillow) with and earlier version (not 2.6.1)
/usr/bin/pip3 install -I pillow==2.5.3
Thanks Bill for the hint in your earlier post, this week.
Can you look into the WSJT python source,
Hi Bill, Greg and all,
I've reloaded Fedora 21 LXDE TC4 and SSH and RDP are available as before
(www.unixservice.com.au). wsjtdev / wsjtdev2
The development libraries are going on, as I write.
Dev for WSJT:
yum-config-manager --save --setopt=fedora.skip_if_unavailable=true
yum groupinstall 'Devel
Hi Bill and
Greg,
WSPR
I've added "-fPIC", in Makefile for "C" and "gfortran" and compiled again.
We now receive and the bar graph shows audio.
Just after "Decoding" starts, Seg Fault.
Can you login (RDP details below) run "wspr40" or "wsjt10" in an LXTerminal ?

Hi Greg,
WSPR
SVN ver 4710 downloaded, installed "autogen" and ran it. Compile error:
/usr/bin/ld: thnix.o: relocation R_ARM_MOVW_ABS_NC against `mtxcom_' can not
be used when making a shared object; recompile with -fPIC

Hi Greg,
Thanks for the suggestion.
Here are the "numpy" packages:

python3-numpy.armv7hl 1:1.8.2-2.fc21

Hi Alan,
Just FYI, if you have installed python-numpy (python2x version), and
your building later versions of WSJT (v10+) / WSPR (v4.0+), which use
Python3, you should remove python-numpy and only install python3-numpy
unless you need it elsewhere.

Hi all,
DEV environment is ready.
"python3-pillow" is installed.
WSJT compiles, runs until "Monitor" is pressed then,
Seg Fault.
Can you guys login and take a look?
Access SSH or RDP to www.unixservice.com.au
User: wsjtdev
pwd: wsjtdev2
Thanks
