Delfi-n3Xt Telemetry Client Registration & Download

UrgentUpdate, urgent message: 14-11-2013

Unfortunately we have discovered a major problem with our telemetry client DUDe which makes abusive connections to our telemetry server (even without frames being received) which leads to a collapse of our server eventually. We have tested our system, but not apparently not extensively enough to discover this before we made the system publically available. I would kindly like to ask you to close the DUDe client directly if you currently have this running. We will try to fix this problem as soon as we can and release a new version of the client before the launch.

Delfi-n3Xt Earth

Delfi-n3Xt sends it data in BPSK modulation on the VHF band. For demodulation using a PC and sound card, you need to tune about 1600 Hz below the VHF downlink frequency of 145.870 MHz (upper sideband) and correct for the Doppler effect. The Doppler frequency can by identified by tracking software. For some combinations of tracking software and receivers, you can automate the Doppler corrections.

To participate in the gathering of data you need a Delfi-n3Xt radio amateur account. Once you have an account you can log in to the server with DUDe to automatically submit demodulated frames and on the radio amateur website to view your submitted data or change your profile. You can register and log in via the following url: DUDe Telemetry Client.

STRaND-1 Telemetry 12-11-2013

STRaND-1 Telemetry 12-11-2013 20:29 UTC

This evening I found it difficult to decode the data that was send by the STRaND-1 satellite. Where not to long ago the amount of frames received where normally more then 500, this even only a hand full. Signal where at times strong enough but the receive combination that I use wasn’t working this evening, or something is changed at the side of the satellite.

Here is something that I could decode:

STRaND-1_BM_12-11-2013_20:29 UTC

Amrad Oscar AO-27 PreFlightLet’s keep our fingers crossed

As of Oct 5, 2012 AO-27 is off-line and the groundstation team is working on a possible solution as one can read on the AO-27 website. After a long periode of silence I was pointed out by N8HM that there was news on the AO-27 website.

Oct 29th, 2013
Recovery operations are underway again for AO-27.
We will try to keep the website up to date with any infomation.

ISS Slow Scan Active

ISS MAI-75 Slow Scan experiment

ISS-MAI-75 29-10-2013 11:45UTCDmitry Pashkov UB4UAD reported that the Slow Scan Television (SSTV) experiment MAI-75 is active during October 28-29, 2013.

He also reports that on October 31, 2013 SSTV images will be transmitted from the ISS on 145.800 MHz showing photographic images of the life and work of the first cosmonaut Yuri Gagarin.

Today at the ISS pass from 12:45 UTC I received the following SSTV image from the International Space Station. The transmissions start late in the pass when ISS is flying over Russia. Therefor I could only receive one image with perfect quality.

Everything you want to now about ISS and amateur radio can be found at the website ISS Fanclub. They are also active on twitter so you don’t have to miss anything.

Since Wednesday, October 16 there is nothing heard from the Scientific satellite CUSat. Maybe you can listen for it on 437.405 FM. Normally the satellite is transmitting in 1 minute interval with 1k2 AFSK.
