[time-nuts] synchronization for telescopes

[Hendrik Dietrich]

Its before breakfast for me now, but you could set up a transmitter on a 
ISM frequency at 5 GHz or 60 GHz, where you have plenty of bandwidth 
(where plenty means 160 MHz or 2 GHz) and transmit your own clock signal.
Either you roll your own by modifying some ham radio open source 
designs, or try to find some cheap surplus.
(A Filter followed by a logarithmic detector might be sufficient for the 
receiver if you settle for Amplitude shift keying, a oscillator with a 
amplifier that you switch on during your clock pulse might be sufficient 
for the transmitter.

Greetings,

Hendrik
