Hi all, After 7 weeks of operating our Flagship Olympic and Paralympic event station 2O12W ( Two Oscar One Two Whisky ). We made over 17.000 contacts and in the early stages I was able to dedicate some time to satellite contacts (over 40 ) and included the USA and Canada . The

Hi Nick , The equivalent noise temperature of an antenna do not depends by it's phisical temperature but only by the noise temperature emitted by the object that the main lobe of the antenna is looking. The equivalent noise temperature of the antenna radiation resistance do not depends by the

Hi James, W5AOO To mount a camera on a beam in order to locate the moon to work EME is a very bad procedure. The correct procedure is to point the antenna system toward the Sun and get the maximum Sun Noise on receiver. As soon the maximum Sun Noise is received please calibrate the Azimuth and

I'd say that differently... Nothing wrong with using the camera. But your point is well taken to calibrate the camera to the BEAM by first pointing at the sun. Then (if your camera survives) the camera is a perfectly good aiming device for the moon and it eliminates any errors in the Antenna

The spectrum issues faced by moon-bounce (EME) operators are similar to those affecting the Amateur-satellite Service, see this video made by volunteers from the British Amateur Television Club (BATC) http://www.uk.amsat.org/?p=10253 73 Trevor M5AKA

Hi All, I too was listening for PROITERES, and made a recording today (Sep 10th 11:15UTC) using my FunCube Dongle. Looking at the spectrum display, I could see the distinctive pattern of two satellites transmitting. It turns out that the orbit of SEEDS II (CO-66) was almost in perfect

Hi Bob, Using a calibrated camera on the Sun is a good system to point the antenna on the Moon only when there are no clods and when the sky is clear. On the other side a well calibrated control box on the Sun Noise is a goood system to point the antenna at the Moon with any wheader condition

Hi Simon, Thanks for the clarification - That was exactly what I experienced and was rather confused until I played back a short recording and realised that I was not having a receiver problem. Regards Ken GW1FKY ___ Sent via AMSAT-BB@amsat.org.
