Maybe a little off topic, but I know a few here have quite decent 70cms stations.
I read about this several days ago & hope to listen for them with my meagre 9 element Tonna. I doubt I could work them with 20 Watts TX power, but I know a few of you here have much more capable stations
Relevant details taken from the Sunday 18th April GB2RS news script:
" The Arecibo Observatory Amateur Radio Club will put the 1000-foot radio telescope on the air for three days for 432MHz EME. The scheduled times of operation for the final day today, 18 April, are 1840 - 2125UTC. Using the callsign KP4AO and 400W the transmit frequency is 432.045MHz and receive frequency is 432.050 to 432.060MHz. KP4AO can be heard with a small hand-held Yagi pointed at the moon and a good receiver. A 15dBi antenna and 100 watts will be enough to work them on CW. "
The Arecibo radio telescope will be familar to many, as it appeared in a James Bond film.
My neighbours were quite impressed several months ago watching me wave a couple of Yagi’s around in the garden simply to listen to a couple of satellites. Imagine how impressive listening to the worlds largest single radio telescope bouncing signals off the Moon would be!
I can only dream of firing enough RF back to be heard in Puerto Rico on 70cms, but I know a few SOTA people have very decent UHF gear. For anyone who thinks EME looks easy, only 7% - 12% at best, of your RF signal that actually reaches the Moon will be reflected back towards Earth.
If you were not aware of the above activity then maybe you could take a listen, & if you do have a capable station, give them a call.
It certainly will be a nice QSL card to have in your collection
Good luck, & Best 73,
