I thought this might interest some - a beacon at 1296 MHz GPS locked in frequency and time of sending, and directed at the moon. Apparently it has been heard with a 1.5 m dish.
Someone is planning doing similar at 10 GHz.

To: DL6LAU <[email protected]>, [email protected], [email protected] Hi Carsten, Indeed a good idea. In regards of frequency, we chose at the 1296 ON0EME EME beacon to use the "start" frequency of the EME band, being 1296.000 MHz, reference locked to GPS to have a frequency standard on the band. People can use the beacon to verify the frequency accuracy of their systems. I believe the start freq. on 3cm is 10368.100 , correct me when I'm wrong. We also chose to start the beacon message at exact 00 seconds of the minute, also GPS driven. This gives the beacon also a timing standard, distance to the moon can be checked and verified. We did have a license restriction we could not start transmitting at 0° elevation with half a megawatt of EIRP, since the antenna is only 6 meters above ground. You may consider talking to Walter ON4BCB who was responsible for the autotracking and the keying of ON0EME, he made the complete interface based on Hannes OE5JFL's design.

Hi guys, we at DL0SHF are discussing, if a 10GHz EME beacon would be of benefit (to someone) ... Seems we could easily have our 7.6m dish with 50W SSPA running towards the moon, when visible in JO54 ... (unless we use the station ourself for QSOs). Would this be interesting? Any suggestion for a frequency? 73ss Carsten, DL6LAU (OP @ DL0SHF) _______________________________________________ Moon mailing list [email protected] http://lists.moonbounce.info/cgi-bin/mailman/listinfo/moon ----- Geen virus gevonden in dit bericht.
