The other day I had a look on Dominiques QRZ.COM page and saw, he claimed to have a beacon on 13 cm as well. The frequency seemed to be quite strange: 2308.037 MHz
My new Kuhne MKU 23 G4 transverter covers certain segements of the band. so I switched to 2304 – 2306 MHz and tried to listen on an IF around 148.037 MHz and was disappointed: nil. I expected a strong signal as the same beacon on 1296.050 MHz ist up to 40 dB above noise under normal conditions.
A weak trace can be seen at the IF of 1392.032 MHz (LO 916 MHz)
I contacted Dominique and he assured, the beacon should be on air. So I tried with the setup, I received ISEE-3 quite a time ago and monitored the path for airplanes. So after a short while, there was a trace to be seen on 2308.032 MHz. Even the keyed carrier could be heard deep in the noise, when larger aircrafts crossed or flew along the path.

So I proudly added beacon #23 to my 13 cm list.

March 23rd, 2017, Update
I had a second try with the MKU 23 G4 this morning and was able to receive the beacon with this gear as well on 2308.032 MHz.
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.
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.
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 😉
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.
Thank you to all paricipants and those who had patience to complete some QSOs!
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.
