[wsjt-devel] Rpi2 , how RF quiet is it

2015-04-17 Thread Richard Bown
Hi Greg and all
As you and others have been playing with the Rpi2, how RF quiet is it,
My operation is mainly 10 mtrs and above , but still suffer from harmonics from 
various data
devices.
If it too far OT please answer direct, but I suspect there may be others 
interested running JT modes
that are looking at smaller hardware
Thanks

Hi Richard,

I've only had the Rpi2 for a few weeks and I've not done any technical
testing RF wise, but the folks over in the WSPRnet site / forums / chat,
they know these mini devices inside out. If there are noise issues, that
group would definitely know about them.

[wsjt-devel] Update - WSJT/WSPR Python3-Pillow 2.6.1 Issue

2015-04-17 Thread KI7MT
Hello All,

After many iterations of building Pillow from source, I think I have a
solution that's working now. I have JTSDK Nix updated to do this when
the user runs $(MAKE) for Debian 8.0 and Ubuntu 14.10 only. Later
versions of Ubuntu do not seem to be a problem.

Windows seems fine sitting on v2.3.0, but, on the next JTSDK upgrade
2.0.1 or whatever it will be, maybe pushing up to / past Pillow v2.8.1
would be wise.

In a nutshell, you should simply install whatever version of Pillow is
in the repo for that distro. For Debian 8.0 and Ubuntu 14.10, that is
v2.6.1 unfortunately.

So the base packages are:

-
python3-pil python3-pil.imagetk python3-tk
-

After installing the base packages, add the required Pillow build
dependencies, for Debian 8.0 (which works on Raspbian also) and Ubuntu
14.10, that would be:

-
libfreetype6-dev libjpeg-dev liblcms2-dev libtiff5-dev libwebp-dev \
libwebpmux1 mime-support tcl8.6-dev tk8.6-dev zlib1g-dev'
-

Following the dependency installation, install Pillow from the terminal
using pip3:

sudo pip3 install --upgrade pillow

The --upgrade flag is important, as you would already have Pillow installed.

You could specify a version if you wish, using pillow==2.8.1 for
example, but I chose to let pip3 sort it out.

After install/upgrade, rebuild WSJT or WSPR from the JTSDK build menu.

I tested WSJT FSK441 wav files and left it in monitor with no failures.
WSPR fires up and runs OK.

I've not isolated the exact issue in v2.6.1, but it's only a problem
long term for Debian 8.0 (Jessie) until the Pillow package is upgraded.
At the moment, due to their pending release, pkg updates are in a freeze
mode , unless it's deemed critical.

Ubuntu 14.10 is a short term support release, end of life date is July
2015, and 15.04 is due out on April 28th I believe.

If anyone has troubles with upgrading Pillow through JTSDK, just send a
message to the devel-list, I'm sure we can get it sorted out.

 Hi Alan,
 
 I've not tried 2.6.2 as that version ins't in the Debian / Ubuntu repo's
 but it is in PyPi ( via pip3 install):
 
 https://pypi.python.org/pypi/Pillow/2.6.2
 
 I tried to stay with versions I could compare with Native packages, with
 the exception of 2.5.3.
 
 Debian (8.0 Jessie) == Ubuntu (14.10 Utopic) is at:
 
 https://packages.debian.org/jessie/python3-pil v2.6.1
 
 I've not tested the Raspbian (8.0 Jessie) on the RPI2, but their
 packaging seems to follow closely with Debian core, apart from the
 Raspbian specific components.

 Hi Greg,

 Fedora 21 now cones with: python3-pillow.armv7hl  2.6.2-1.fc21

 So, does 2.6.2 work?

 I'm not sure as I've upgraded pillow using pip to 2.7.0.
  
 /usr/lib/python3.4/site-packages/Pillow-2.7.0-py3.4.egg-info

 Today, I did a yum update and I now have
 /usr/lib/python3.4/site-packages/Pillow-2.6.2-py3.4.egg-info
 dated Apr 15 07:20

 Today,
 wsjt10 runs fine via RDP session, (headless, there is no Mali driver yet)

 Back on Jan 15, there was, when the Banana Pi was loaded, pillow 2.6.1.

 Keep Smiling

 Hello All,

 While updating WSJT/WSPR build documentation, I've come full circle 
 on the Python3-Pillow 2.6.1 segfault problem that many have 
 reported. I'm need of assistance in trying to debug / generate a 
 work around, as this has gone well past my level of knowledge with Python.

 This issue affects both Windows and *Nix, but seems to be isolated 
 to the Pillow 2.6.1.

 THE PROBLEM

 When using Pillow 2.6.1, WSPR and WSJT will both segfault, almost
 immediately, either at decode time for WSPR ( sample *.wav file or T=50
 to 55 of the 2min cycle ) or at the end of the first FSK441 cycle (
 first whole minute? ) with WSJT. Neither application present the 
 issue when using Pillow  or  2.6.1 on my test distro's.

 TESTING PERFORMED

 I've performed several tests with various versions of Pillow, primarily
 on Linux. On my Ubuntu based installs, after installing JTSDK Nix, those
 distros using python3-pil 2.6.1 ( Ubuntu 14.10, Debian Jessie for
 example ) will build correctly but fail as above.

 Removing python3-pil and python3-pil.imagetk, installing the required
 build dependencies:

 libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev
 libwebp-dev tcl8.6-dev tk8.6-dev

 then installing ( via pip3 ) Pillow==2.5.3, ==2.7.0 or ==2.8.1 ( the
 latest Pillow release ), neither WSJT nor WSPR present the segfault.

 At this point, I would think the import instructions in WSPR.py an
 WSJT.py are OK, but I don't know where or how to take this any further.

 Without getting this resolved, we will not be able to update WSJT / WSPR
 in any distro using Pillow 2.6.1 as the default package (Ubuntu 14.10
 and Debian Jessie at present ). I believe there are Fedora based distros
 also using Pillow-2.6.1, but I am not as familiar with
