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)

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.
