[aprssig] Satellite Station

I have been playing about with power supply solutions here and have come to
the conclusion the best is a battery.

What I am going to do is a bit different though.

A LINUX computer will run predict.

When a satellite is above the horizon according to predict, I will throw a
relay on a board off the printer port.

The relay will disengage the battery from the charger and throw it across to
the radio to energise for the next pass.

When the satellite has gone back below the horizon, the relay will
de-energise and flip back to the charger and turn the radio off.

Anyone automated to this extent in their sat shack ?
