don't know where this went, but: from the archives back in 2011 tvb said Hi group. I've been contacted by a helpful person who is willing to undertake "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 Thanks, /tvb > > Failing one of the time nuts supplying me an antenna (anybody have a spare > assembly they can sell me?) > How often do the 2200 type antenna come up on Ebay? > > > Many thanks, > mark > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
