Just a thought, did these units work after the GPS Week rollover. Seem to think they were all pre this date.

I've been contacted by a helpful person who is willing to undertake a group buy of Austron GPS antennas. Here is what he said: "If I can get enough interest, there's a real possibility that better-than-original Downconverter Antenna Units for Austron GPS can be manufactured for me. Applies to all known Austron GPS Receivers such as 2200, 2200A, 2201, 2201A and variants. These units all send 15 volts and 10Mhz to the antenna unit which multiplies this and uses it to derive a local oscillator signal of 1500MHz in the antenna unit itself. 1575.42MHz - 1500 MHz = 75.42MHz which is sent back down the coax from the antenna unit to the gps rx. (All these receivers are useless without the downconverter antenna - and there have to be lots of 'em in the hands of time nuts)" If you have questions or are interested in participating, please contact Roland directly at timebea...@gmail.com Thanks, /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
