Delfi-n3XT Telemetry 04-01-2014 12:09 UTC

Finally I was able to decode some Delfi-n3XT data. I used a FUNcube Dongle Pro+, SDR# in USB mode with a bandwidth of 3800 Hz and the DUDe software provided by the Delfi ground station team. A total of 251 packets received and forwarded to the ground station server.

Triton-1 Telemetry 04-01-2014 11:56 UTC

Decode: FUNcube Dongle Pro+, MixW (Packet VHF 1200 baud (satellites PSK))

It is tough to decode Triton-1 because the frequency is drifting a lot. This decode was done at 145.823 MHz USB.

FUNcube-1 Telemetry 21-12-2013 20:01 UTC

After a longtime I gave FUNcube-1 a try using my FUNcube Dongle Pro+. The satellite is running in Eclipse mode, so the Beacon is running in low power and transponder is active. A total of 68 frames decoded and experiencing strong fading on the signal. I guess the satellites is spinning a lot.

In the above spectrum you can clearly see the beacon signal on the left and the transponder signals on the right.

More visual bandwith

Posted on by

More visual bandwidth thanks to an UHF to HF down converter in combination with the AFEDRI SDR. This combination will give me a 2Mhz wide spectrum on 70cm.

High Sierra Microwave Model 432M7The idea was, to use the bandwidth of the AFEDRI SDR in combination with a 70cm down converter. After searching the Internet I found the website from High Sierra Microwave and ordered the 432M7 SDR friendly down converters.

Specifications:

The Model 432M7 is designed using a two stage pHEMT MMIC LNA, each stage followed by a SAW filter, which provides over 75 dB of image rejection. It has a crystal controlled PLL local oscillator at 425 MHz, a double balanced mixer and IF filter. The low frequency IF of 7 to 13 MHz is a great fit for the many HF SDR receivers, such as the Softrock and SDR-IQ series.

AFEDRI High Sierra

Lets see how this down converter will perform in comparison to the FUNcube Dongle Pro+. As you may already now, I use SpectraVue together with my AFEDRI SDR and when one connects a down converter you can use the External Radio Setup. For this combination I use the following settings.

Custom Inverted IF = no
Custom Ext Center Freq = 435000000 Hz
Custom IF Center Freq = 10000000 Hz
Ext IF BW = 10000000 Hz

Lets see what this combination brings in the next couple of weeks. I hope this will make it easier to receive all the new satellites that have there downlink frequency above 436.000 Mhz. With this combination I should be able to receive the whole spectrum from 436.000 – 438.000 Mhz.

Tonight after a long period I received DANDE and decoded more then 60 frames transmitted by this satellite.
