First WSPR beacon on 144 MHz in DL
10-01-2013
Soumis par: ON4AVJ
On September 14, the first WSPR Beacon, DB0XIT, started working in Germany. WSPR is an abbreviation for “Weak Signal Propagation Reporter Network”. It is a network built to observe propagation conditions using weak beacons. DB0XIT is transmitting on 144,4890 MHz USB with 3 W horizontally polarized from Europe`s highest headgear in Göttelborn, Saarland. The antenna in use is a stacked angular dipole with omnidirectional characteristics at a height of about 457m over Sea level. The beacon is connected to the internet to observe propagation conditions in Europe. Interested people might have a look at the Internet[1,2] to get more details about WSPR. There you can also download the WSPR software for free in the case you want to get active on WSPR. 2m is not the only Band for WSPR. There are also beacons using shortwave bands. The Windows-Software distributed by the WSPR-Website supports working on all bands.

Reunion de la commission IARU-C5 a Vienne
20-11-2012
Soumis par: ON4AVJ
En Avril 2013 se tient á Vienne la réunion des commissions VHF et HF de l'IARU-R1. La commission C5 s'occupe des questions VHF et les fréquences supérieures. A cette réunion on discute les propositions sur le bandplanning, des différents modes, des contests, etc. Ce sujets sont alors repris dans le VHF Managers Handbook.
Si vous avez des suggestions vous pouvez les envoyer à l'adresse vhf [at] uba [dot] be (subject: Voorstel%20voor%20Wenen%202013) (email suivante.) Ceci seront discuté par la commission VHF de l'UBA mi-décembre.
ARRL Microwave EME Contest
14-10-2012
Soumis par: ON4AVJ
The ARRL Microwave EME contest took place on October 6/7 and stations from all over the world participated on frequencies ranging from 2,3 to 10 GHz.
This year, I took part in the 2,3 GHz band and found good activity despite the very high degradation due to the moon being near apogea. I made a total of 33 random QSOs: 32 in CW and 1 mixed SSB/CW.
Among the stations contacted, R3YA is a new DXCC for me and a first between ON and Russia on 13 cm. The smallest station contacted was PA7JB, who was surprisingly good copy with his little 2,4m offset dish and 100W only.
Antenna is a 3,6m mesh dish with circular polarization and power at the feedhorn is about 150W
