NA1SS calling GB4YOTA

August 8th, 2017

Another ARISS contact with an YOTA event in England was scheduled. HAMTV should be operated by Paolo Nespoli, IZ0JPA. As some nice video sequences could be received on 13 cm, nothing was heard on the 2 m downlink on 145.800 MHz in FM.

Reception of Live Video from Space: Thomas Pesquet, FX0ISS

February 13th, 2017

Today another ARISS contact has been established between Thomas Pesquet, FX0ISS aboard the Intenational Space Station and Collège André Malraux, Chatelaillon-Plage, France. As expected, the onboard DATV transmitter (HamTV) was in operation.

Blank transmissions have been received earlier, but today I could receive the TV pictures for my very first time. There was a lot of fading, but I managed to record a couple of sequences.

As the pass went overhead, I lost the signal, when the ISS approached the zenith, because the rotor had to turn 180° and it is too slow to catch up the bird again (full length video here best quality from 2:50 to 4:50).

The frequency used was 2.395 GHz. The equipment installed for reception is a 3 m dish with linear polarisation, a Kuhne MKU LNC 23 converter and a TT S2-3200 DVB-S receiver card in my PC with Tutioune3200 DVB-S software by F6DZP.
