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.

 

Compilation of European VHF/UHF/SHF Activity Contests

January 16th, 2017

Most of the VHF/UHF/SHF enthusiasts will know very well about the activity contests in Europe. But there is a number of just interested radio amateurs, who would like try on these bands. They will find dates and times as well as links to the rules of certain contests in my list. If there are any monthly activity contests, not listed, please let me know.

Surprise, Surprise!

January 12th, 2017

When looking for the annual results of the Italian Activity Contest 2016 on 1296 MHz yesterday, I was really surprised, to be the winner. I haven´t expexted this, as Giorgio, IK3GHY, had a higher score in total all the time. But as he won in 2015, he was out of competition in 2016. I have to respect his success and congratulations for your extraordinary score, Giorgio!

But anyway, it was great fun to work the italian lads every 3rd Tuesday in month. Hopefully, there will be enough time to be QRV in the 2017 events. I am also looking forward to go to Italy in October, meeting friends in Venice and at the Alpe Adria meeting near Udine.

Steve, IU1EAF, will be the contest manager in 2017 and the rules have changed too (english version online now). Thank you to Alfredo, IK2FTB, for all the work in the past year.

 

Nice Tropo this Afternoon

December 20th, 2016

There is some nice troposheric propagation this afternoon. It looks promising for the NAC, IAC and UKAC this evening on 23 cm. When looking for DB0XY I saw this situation:

Testing the new Kuhne MKU 23 G4 on 13 cm

November 22nd, 2016

Today I configured the MKU 23 G4, I ordered from Michael in Friedrichshafen to perform a RX test. Via aircraft scatter it was no problem to receive the beacons OZ7IGY in JO55WM over 670 km and OK0EK in JN89VJ over 689 km. The sun noise is at a level of 6 dB.

The motivation is high now to configure the TX line as well 😉

November IAC/NAC/UKAC on 23 cm

November 17th, 2016

I have been very short in time for this activity evening, but managed to work 10 Stations within one hour. The first three were the three Johns from UK: G4BAO, G3XDY and G4ZTR.

IARU Region 1 UHF/SHF Contest ist over

October 2nd, 2016

Despite a late start and easy going operation, at least 63 QSOs filled the log for the 23 cm band. HA5KDQ from Budapest (JN97LN) became my new contest-ODX with 829 km. As can be seen in the map, the eastern directions are my favourite ones.

Strange Tropo today

September 28th, 2016

During the morning I was able to monitor GB3FM in IO91OF on 1297.050 MHz and G8MBU in IO90IR on 1296.800 MHz. Now in the afternoon F5ZCS in IN87PT on 1296.959 MHz came out of the noise with a strong signal of 549 with fast QSB. It is my 53rd beacon on 23 cm. The weather here in Mainz doesn´t look like tropo: 8/8 cloudy and wind at 40 km/h.

July-Results of Italian Activity Contest published

September 8th, 2016

It´s nice to see me as #2 in IAC. To meet the lads from Italy on 23 cm every 3rd Tuesday in month is always big fun. Unfortunately I missed the August event due to my dismantled rotor. Instead I met Giorgio, IK3GHY, at the EME Conference in Venice. Also big fun to see his new amplifier for 23 cm there, wow!

2016-09-08-21_40_02-2016_iac_annuale_1k3-4-pdf-adobe-acrobat-reader-dcEverything is up and running again. Jacek of Spid in Poland gratefully did a great job in fixing my rotor. So I expect to be present in the September-IAC.
