[time-nuts] Fwd: [Moon-Net] [Moon] 10GHz EME beacon?

[Dr. David Kirkby]

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.

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.

Success with the project !

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
