Decoding DMR (mototurbo) from webSDR http://zr6aic.giga.co.za:8902 using DSDPlus 1.7 and VB-cables on Windows 7

Screenshot of working DMR

1) Install VB-cable from http://vb-audio.pagesperso-orange.fr/Cable/index.htm

2) Download and unzip DSDPlus from http://www.dsdplus.com/download/dsdplus/DSDPlus1p074.zip

3) Create a start_dsdplus.bat in the directory where you unziped the DSDPlus1p074.zip zip file.

4) For now enter the following in the bat file DSDPlus.EXE -i1 -o2 -fr

5) Set the playback device as follows making the VB-Cable the default device and Speaker just ready.

6) Set the recording settings as follows.

7) In the Recording tab set the VB-Cable as default device and Stereo Mix ready

8) Set the sound levels as follows.

VB-Cable level about 10% and Speaker level.

9) Volume settings

Volume Settings.

10) Now run the start_dsdplus.bat file that you created in step 3 and check that the numbers correspond to the red in the pictures below.
i = Audio input to DSDPlus and o = Audio Output from DSDPlus

10.1) Input to DSPPlus must be from VB-Cable and not any other device (Stereo mixer in my case).

10.2) Output must go to Speakers in my case to 2.

10.3) Your Audio input and output configuration should be different to the one I have.
10.4) You will then need to change it in the start_dsdplus.bat file and then re run start_dsdplus.bat file. and refresh websdr website (CTRL F5)
Then re-tune websdr DMR frequency to 438.225Mhz FM

11) If your Audio Input and Output configuration is correct you will have to just set your audio levels coming from webSDR and going to speaker.

DSDPlus command shell details

12) Then go to my WEBsdr in your Chrome or Firefox browser http://zr6aic.giga.co.za:8902

Select 70cm_dmr band and tune frequency to 438210.88 Fm

13) There is small burst of data with now sound wait for the long bursts of data witch is normally conversation. I think the small burst is just data and you will not hear anything.
(Sound level to DSDPlus input should not be to strong)

Hope this help.

I will add some videos tomorrow.

log PSAT cubesat 25 September 18:20GMT (APRS)

ParkinsonSAT (Psat) cubesat 25 September 18:20GMT

CW message from PSAT Cubesat. "PSAT EVPT32DC 7.23V" , "PSAT EXPT32DC 7.24V 0DBM" , "PSAT EXPT32DC 7.25V 0DBM"

Psat is the next APRS satellite design from students at the US Naval Academy. Although we have built 5 previous APRS satellites, only the original PCSAT-1 is still in orbit because all the others were deployed from the Shuttle and at the low altitude, have re-entered. PCSAT-1 (W3ADO-1) is partially operational when ever sun angles are optimum a few times a day; and you can see its live downlink on http://pcsat.aprs.org.

WREN The small 5X5X5cm Cube Satellite. (PocketQube)

WREN The small 5X5X5cm Cube Satellite.

The tiny PocketQube satellite WREN is just 5x5x5 cm yet is equipped with a camera for Slow Scan TV (SSTV) using the Martin-1 format, a gyro, a magnetic field sensor, momentum wheels and pulsed plasma microthrusters. The camera has an image processing system which can find the position of the Sun and the Earth automatically.

WREN Beacon on webSDR (http://zr6aic.giga.co.za:8902

Payload.
1) Beacons on 437.405 MHz (+/- 10 kHz Doppler shift)
Satellite sends 1.6 seconds in AFSK. Then it waits for 6 minutes for a signal.
It waits for a silent FM signal and Morse-like code. (So just keying the mike by hand will do.)

Application Blocked by security settings (Java error when running applets in Browser)

Application Blocked by security settings

I have upgraded my java and the java plugin in my Chrome browser and then tried to use my webSDR website that includes applets in its content and then got this error above.

All the Google links was referring to adding the webSDR link in

Control Panel > java > Security > Edit site list. (add webSDR url http://zr6aic.giga.co.za:8901/) and (add webSDR url http://zr6aic.giga.co.za:8902/)

Well, this did not work for me (the default java control panel java console did not have the security options to add site links)

(I used windows 7 with a Chrome browser) and the java was update to java 7 update 3 (build 1.7.0_03-b05) when this error above appear. :-(

I had to run the application called "Configure java"

By entering it in my start menu search and then executing the application

Configure java

I then had the application tab option as described above to added the site links.

Click on the Security tab

Click on the Security tab and add your web url in the edit site list

Click on ok and restart you browser and try the url with java applet.

http://zr6aic.giga.co.za:8901/

You will then get another message box "Do you want to run this application?"

Just accept and click run and your website with applet content should now work.

hope this help

Enabling Java for Chromium Web Browser on Linux

Enabling Java for Chromium Web Browser on Linux (for webSDR)

First install Java jdk or jre from http://www.oracle.com/technetwork/java/javase/downloads/index.html

JRE = runtime only you cant compile java only run java

JDK = You can compile and run java

I installed the JDK as I am also a java developer (1.7 latest is fine) jdk-7u11-linux-x64.tar.gz

Change to the directory where you saved the download

Open command terminal

cd /home/anton/Downloads

tar -cvf jdk-7u11-linux-x64.tar.gz

It will unzip all the files creating a directory similar to this jdk1.7.0_11cd /usr/lib/chromium-browser/plugins

cd jdk1.7.0_11

Need to add the java plugin into the Chromium Web Browser
The path mite be different on your Linux change to fit

cd /usr/lib/chromium-browser/plugins
sudo ln -s /home/anton/Downloads/jdk1.7.0_11/jre/lib/amd64/libnpjp2.so libnpjp2.so

Need to change the System default java to point to new java JDK I know installed above

sudo update-alternatives --install "/usr/bin/java" "java" "/home/anton/Downloads/jdk1.7.0_11/bin/java" 1

Know take you browser to http://zr6aic.giga.co.za:8901 and see if webSDR is know working.

Here is a map of webSDR receivers.

Add the Asus Xonar D1 sound card to my websdr

Add the Asus Xonar D1 sound card to my websSDR server to widen the 40m Band with to 192Khz

Asus Xonar D1 192Kb Sampling (one A/D stereo input)

The Sound Card has only one A/D input but it has drivers for Linux. (-;
My existing M-audio Delta 44 cards has 4 mono inputs but can be link to give you 2 Stereo inputs. it has only 96Kb sampling capability. (Max webSDR band with would be about 96khz) Where the Asus Xonar D1 will give you the 192Khz band with but uses one PCI slot on your server there for you will run out of PCI slots in your computer if you want to upgrade all your Delta 44 cards to Asus Xonar D1 cards.

Here is my .asoundrc config file with the combination of my M-audio Delta 44, Asus Xonar D1 and on board IXP sound interface. (one IXP, two M-audio and one Asus card)

Here is the Simplified file below this one there is a more complex file with some remapping if you want.

New 20m SDR receiver added to WEBSDR

(Softrock receiver) Where can I get a softrock recever http://www.giga.co.za

I have build my first Softrock Ensemble RXTX for the 30m, 20m and 17m bands.
more details on the receiver and the assembly details can be found at http://www.wb5rvz.com/sdr/ensemble/.

Building the Softrock Ensemble RXTX

Testing the Local Oscillatory

Signal is pure sine wave

I had to add a command line utility to the Linux webSDR server to control the frequency of the receiver via usb port with the following program usbsoftrock.
The program can be found on Google code https://code.google.com/p/usbsoftrock/downloads/list
You will need to compile the code before you can use it.
here is the command that you could use after compilation

sudo usbsoftrock status
Version : 15.12
USB SerialID: PE0FKO-0
Startup Freq: 14.210000 (x 4.00)
Xtall Freq : 114.285000
Smooth Tune : 3500 PPM
Si570 I2C : 55 Hex
BPF Enabled: 0

Set the frequency you require
sudo usbsoftrock set freq 14.210

The frequency was a few khz lower and I had to calibrate the frequency using the following command. You can retrieve the frequency at which your Si570's crystal oscillates with the command sudo usbsoftrock calibrate

Version : 15.12
fXTALL = 114.207544

Calibrating the frequency with the value you got above.

sudo usbsoftrock -x 114.207544 set freq 14.125
Version : 15.12

Checking the frequency. sudo usbsoftrock getfreq

Version : 15.12
Frequency : 14.089549 (x 4.00)

here is the command list

COMMAND is one of
calibrate (may require -s option)
getfreq
getregisters
interactive
getptt (-h option for Mobo only)
getkeys (PE0FKO+TF3LJ+Mobo)
gettone
ptt {on|off}
set bpf {on|off} (PE0FKO+TF3LJ+Mobo)
set bpf_addr <band> <filter> (PE0FKO >= 15.12+Mobo)
set bpf_point <crossover> <f in MHz> (PE0FKO+TF3LJ+Mobo)
set lpf {on|off} (TF3LJ+Mobo only)
set lpf_addr <band> <filter> "
set lpf_point <crossover> <f in MHz> "
set freq <frequency in MHz>
set si570_addr <i2c address in decimal>
set si570_multiplier [band] <decimal factor> (PE0FKO>=15.12+Mobo)
set startup <frequency in MHz> (PE0FKO+TF3LJ+Mobo)
set xtall <frequency in MHz> (PE0FKO+TF3LJ+Mobo)
status
