All,
If anyone is interested, there's another one of these that just came up for
sale. The guy shipped mine the day I e-mailed him I sent payment. He's jet fast
on this. You'll need a GPS antenna (magnet mount will do) like Garmin, etc.,
and must be an amplified antenna that uses 5 Vdc. Also needed is a -48 Vdc
power supply.
GPS Frequency Standard 5 PPB;
