Connection will established between Soundmodeum
and AGW onlinekiss

Click Option select  mirror incoming data to com port.
If the two LED shine GREEN at AGW = Connection was established
and no error for data to flow in and out.
Otherwise if one or the two LED are RED check the COMS and the other parameters .

KySat-2 Decoder
Add COM2 to custom port at the new KySat-2 decoder.

QSOs near the beacon !!!

QSOs near the beacon drives the auto tune crazy !!!
this was noticed when the transponder driven heavily over Europe.
The beacon signal  over Africa is quite and strong .
Graphically restricted auto tune range help beacon tuning.

GomX-1 Modulation !!!

GomX-1 transmitting a strong signal every 10s

GomX-1 does not use the standard AX.25 or AFSK format used for packet communication
GomX-1 uses 4800 baud MSK modulation at the two tones 2400 and 4800. This mode is not supported by most major TNC providers. So the recommended receiving option is to record the audio from the entire pass, using the line-in port on a PC with correctly adjusted amplitude. These recordings can then be software demodulated by gomspace.

A softare modem, based on GNURadio will be released soon. If you are interested in helping developing and testing a software modem for MSK, please say so.
For more see GomSpace GOMX-1 webpage

MOVE Telemetry Receiver !!

MOVE Telemetry Receiver , simple nice program ,works as it is!!
Works ok with analog rig ,but with some difficulty due to new keps and for the long time between telemetry packet.!!
With IQ audio works very easy - audio rooted via XP Window Mixer to the selected audio input devise -
Replay via HDSDR ,Keep audio level low  about 20% for easy decoding  .....

First Move-1 Cubesat HP

Warbler – 1200 Bit/s BPSK AX.25 soundcard demodulator.

My friend San  Satou Tetsurou decoded Move cubesat by  Warbler !
Warbler is a piece of software which can be used to demodulate a 1200Bit/s AX.25 BPSK signal (e.g. from AMSAT-OSCAR 16/PACSAT or ITAMSAT-OSCAR 26), using the PC’s soundcard.

I've re tested with move IQ audio file .

AO-73 FUN from Europe to Africa

AO-73 FUN from Europe to Africa


The PicoDragon cubesat  developed by the Vietnam National Satellite Center (VNSC).

November 26, 2013


Keps are old to track any new satellite !!!
Pointing the antenna to the max elevation of the satellites chain was a good solution to prevent more wear and tear to the rotator and receiving more new satellites.
Today I got more signal :) I got many strong packet frames which I was unable to decode it yet ,and a long toooot signal ,another strange one !! I was able to copy CubeBug-2 satellite. more than 7 frames was decoded.

Receiving AO-73 telemetry via Analog Rig !!

Funcube Dongle  works very well with Dashboard  Telemetry Decoder .
During last pass I gave IC910 a chance to say hello to AO-73.
Connecting the Rig audio output to PC soundcard input.
Selecting soundcard as the  input device at FC Dashbord decoder.
Clicked - capture from soundcard option. I received 136 frames .
Tuning was so easy with software auto tune option.
Sometime the manual tuning  gave high rate than auto tune!
Upload was ok too to warehouse.
Here is a simple image of the setup:

FUNcube-1 (AO-73) Transponder Tested.

Howard Long G6LVB working AO-73 while Ciaran Morgan M0XTD captures
 the downlink passband data using a FUNcube Dongle Pro+ and Microsoft Surface Tablet.

The first test of the FUNcube-1 (AO-73) SSB/CW linear transponder took place today. The transponder was successfully commanded on at 10:49 UT and functioned perfectly during the pass.
 A test of operation using portable stations was made from the Bletchley Park car park. Howard G6LVB and Trevor M5AKA, operating stations GB3RS and G0AUK, worked each other at 10:53 UT. Both stations ran 5 watts PEP to Arrow antennas and signal reports of 55 were exchanged.
The transponder was commanded off towards the end of the pass.
Testing and analysis of the telemetry data from FUNcube-1 (AO-73) is continuing.
Thank you to all stations who have provided telemetry so far. More telemetry data is needed to enable the FUNcube team to characterise the satellite.
We would encourage more stations to download the Dashboard software to receive the telemetry and upload it to the Data Warehouse.
