update: 21.April 2014
I could manage to run
GNURADIO 3.7.3 on the board.
The compile process needs some hours.
Additionally I could compile the OSMOCOM source
for the use with RTL-SDR, SDR-IQ and other hardware.
GNURADIO is running but only uses one CPU in the moment
so the performance is bad. CPU
optimization needs a recompile of GNURADIO.
I tried it with the following command line option of
cmake -DCMAKE_CXX_FLAGS:STRING="-march=armv7 "
-DCMAKE_C_FLAGS:STRING="-march=armv7 " ../
The result looks better now both
CPUs are in use.
Cubieboard 2 running GNURADIO
could be tried out,
it is running on low SDR bandwidth around only 16kHz for
audio decode in USB mode.
2 running GQRX with SDR-IQ
IT looks ... THE LIMIT
NOW WAITING FOR BOARDS WITH MORE CPU-POWER.

Debian Jessie will go out in
2015 so some preview what will work there...
I used the Debian Jessie Image from "slovenia".
I installed MATE-Desktop, Slim and Fluxbox ....
for a tryout ...
also newer SUNXI-kernels are working well.
Development System QT5 is now in USE ...
So it is possible to use the newest Versions of

Banana Pi arrived some days ago. It uses the
same CPU like the Cubieboard2...
so most of work done for the Cubieboard2
before, will also run here.
I made a first test with the BananaPI
Lubuntu image, copied my compiled
Cubieboard2 versions to the BananaPi and it
After removing the microphone and setup an
external input socket
I checked WSJT,WSJTx,WSPRx and WSPR.
Also the A20
kernel updates from DANAND
running. (actual version is 3.4.103c)
Additionally I tried a 20% overclock of the
CPU to 1.2GHz and it looks ok.

update: 18.October 2014
I tried out the new CUBIAN
It uses MATE-Desktop and Debian
So it is possible to use some newer packages.
and tried out under Cubian X1 (DebianWheezy).
CubianX1, MATE and FREEDV
For the BananaPi I found a better
working kernel update from "slovenia"
package which can be transferred from
Cubieboard2 to the BananaPi.
After installing 2 additional packages it worked
also with Lubuntu14.04.
Lubuntu with Kernel 3.4.104 and FREEDV

Debian Jessie Images for Cubieboard/Cubietruck
BananaPi Jessie Image
(v1.6 Kernel 3.4.105)
Cubieboard Jessie Image (v2.9 Kernel 3.4.105)
install a minimal graphical
environment with Mate Desktop with
So i tried it with the BananaPi
1. download Jessie image and put it on SD Card
2. login as root and change your password
3. adduser maybe "bananapi"
5. login as root
6. install graphical environment (slim,Mate) and
some setup tools
apt-get install xorg
apt-get install slim
apt-get install mate-desktop-environment
apt-get install synaptic
apt-get install console-setup
7. setup for keyboard layout and other local
8. switch off DPMS (no video anymore after 10 min
add a file as root
# SWITCH OFF DPMS
Option "DPMS" "false"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
9. reboot and login in SLIM
10. install your needed packages with synaptic
Some newer programs for amateur radio use
in the official sources of Debian Jessie
RTL-SDR and other tools for HackRF,
and some more
work your desktop can look like

Testing K9AN WSPR decoder
with WSPRx (r4178)
K9AN released some time ago an
modified WSPR decoder.
Instructions how to use and compile can
be found here.
I compiled the decoder and renamed
(replaced) the original file "wsprd" in the
wsprx_install directory with the
modified version from K9AN... and it
For comparision of decoder performance i
let run 2 instances of WSPRx r4178
on the Cubieboard2 or on the BananaPi.

The Funcube Dongle Pro +
is a nice toy to play with and can make a
complete monitoring SDR for the A20 boards with
So i checked it with nice results...
I got finally working:
LINRAD (in combination
The audio bridge is made
via pulseaudio server.
Note: I used the
original firmware of the FCD Pro+
(not the RPi Version).
So the useable bandwidth ist 192 kHz.

an SMA input connector. I ordered

decoding JT65/JT9 after a
It looks the stick has much better
performance because of the good LO
and the new tuner.

Compile of MSHV V1.06 from LZ2HV
as ARM Version on my ORDOID C1.
But it is not working there
because of soundcard
So I ported the binary to the
Cubieboard2 and it is running.
MSHV is supporting the following
weak signal modes

CPU-load (1st test FSK441)
OPENWEBRX from HA7ILM was
transferred to the BananaPi and working
1MHz bandwidth on the BananaPi with
RTL-SDR and shortwave converter.
The CPU load is about 50-60%.
running OPENWEBRX on 40m Band
After some time i made a new
test with the actual ARMBIAN
5.20 on the Cubieboard2.
I recompiled fldigi, WSJTx,
linrad and GQRX and testet it
with the RTL-SDR(tcxo).
running Fldigi 3.23.15-02 with
Linrad 4.10 and RTL-SDR(tcxo)
