LA1K / LA1ARK / LA1UKA

First entry in the VK3UM Memorial EME Contest

Since we got our 23 cm EME setup operative a short while ago, we have been very fascinated with the moon. Recently we made a bunch of QSOs, and have been eager to make even more.

We were very excited when we found that the weekend of 13-14 April was home to the VK3UM Memorial EME Contest, a CW/SSB EME contest for the 23 cm band. Up to this point we had only worked JT65C QSOs with our setup, so we were a little skeptical – but eager to try.

Jens (LB6RH) and Magne (LA1BFA) concentrating deeply to decipher moonbounced morse code.

With a 3 m dish and 100 W at the feed, we have an Effective Isotropic Radiated Power of approximately 100 kW. In a world where the big guns have 1 to 10 MW or more, it was suprising to learn that we only qualify as a QRP station.

Even with our modest station, we were able to work quite many QSOs (mostly carried by the large stations). These are summarized below (all QSOs made on Saturday 13):

CallQRG [MHz]ModeLoc
OE5JFL1296.018CWJN68
OK1CA1296.020CWJN79
OZ4MM1296.024CWJO55
SM6CKU1294.044CWJO67
UA3PTW1296.022CWKO93
PI9CAM1296.027CWJO32
OK2DL1296.029CWJN79
SP6JLW1296.029CWJO80
LZ2US1296.017CWKN12

This first entry in the VK3UM Memorial has inspired us by showing that CW EME on 23 cm is so readily available. Seeing the big stations work QSO upon QSO also begets a desire for a more QRO amplifier. Perhaps we will need to design something that accompanies the newly increased legal limit (1000 W)… We will definitely be back next year!
