144 MHz EME: Back in business


There was a lot of work to be done in the garden during the last weeks: No, not only mowing gras, but also a larger hole had to be excavated and filled with concrete. Then mounting a stable metal pole on it, a rotor and, of course, another antenna. An 8m long 12 element DK7ZB Yagi was the choice, 14.1 dBd gain. Not much at all for a 2m EME system, but we’ll see what’s possible. 

On Saturday afternoon everything was ready to go for the first test. The automatic tracking system worked perfect and turned the antenna exactly to the moon, who was almost in the south. Just only 30 degrees elevation and almost 2 dB additional pathloss – not very promising. Will this be enough to hear someone?

It was enough! UA4AQL was easily detected in the waterfall, calling cq in JT65 mode. One periode calling and he came back to me – whow, what a good feeling! After this initial contact, four more QSO’s followed with LZ2FO, RX1AS, OH4LA and F4DJK.
