CubeBUG-1 01-10-2013 09:55 UTC Active
The small satellite CubeBUG-1 was active during this pass. I am still unable to decode the data because I am not able to receive a high enough signal. The transmissions are in a clear pattern as you can see in the below SDR spectrum.
DANDE Telemetry 30-09-2013 09:12 – 09: 15 UTC.
This morning my first try to decode the telemetry data from the new satellite DANDE. I could decode in total 12 frames during this short pass.

Received data can be downloaded at the following location: DANDE Download location
DANDE was launched with the Falcon 9 from SpaceX’s pad at Vandenberg carrying Canada’s CASSIOPE satellite.
It is been a while for me, but today I had some pretty good SSTV reception from ISS on 145.800, the SSTV mode was martin1. For decoding SSTV data I use MMSSTV.

The transmissions started late in the pass and I think it has to do with the fact that our Italian astronaut is taking in consideration his radio friends in Italy. I was a little premature with this comment and IK1SLD gave the right information. He wrote to me via the AMSAT-BB mailing list the following.
Luca Parmitano doesn’t use the Kenwood TM-D710, this radio is used by Russian crew. The MAI-75 Experiment is a Russian experiment and the crew activates it when Moscow has AOS, so we lost 50% of the pass. Luca only use the Ericsson radio in the Columbus module.
Thank you Claudio (IK1SLD) for this update.

During the second day of the MAI-75 Experiment I could only receive and decode one image. It seems there where some problems with the radio because there was a carrier but no data being transmitted.
Delfi-C3 (DO-64) Telemetry 18-08-2013 19:30 UTC
All those carriers around the receive frequency make it difficult to decode some telemetry data, but this evening we could receive about 150 frames.
Lets see what information is available from those frames. Nice to see that this Satellite that is already 1938 Days in space is still sending so many frames after every reboot.

Here is an image from the orbit that STRaND-1 had during this pass. AOS was in the North-East and LOS almost due South. I am puzzled why STRaND-1 is sometimes much stronger when switching to LHCP. This was such a pass and in the images below you can see the difference.
Date and Time: 04-08-2013 18:03 - 18:17 UTC Object : STRAND 1 Max elevation: 54 degree Azimuth : 018 - 184 degree Polarization : LHCP Strongest Signal : max 30 dB above noise Frequency : 437.568000 MHz FM +/- doppler Status : Active Remark : LHCP much stronger then RHCP, 518 Frames

Signal difference between LHCP and RHCP in the beginning of the pass. You can see the difference when I switch between LHCP and RHCP.
Further in the pass and closer as you can see in the signal strength. And again a big difference in signal strength when switching between LHCP and RHCP.
The last image, is the decoded data from the frames that I received during this pass. It looks that the solar panels on the +Y array are producing the largest amount of power. Does this tell something about the fact that signals are stronger when using LHCP.

SDR# Spectrum, as you can see very strong signals from this Cubesat.

Decoded the data with the software decoder from DK3WN.
