Can someone confirm what the downconverted frequency is for an Odetics
GPStar? I have been told that it is 35.42 MHz. but I would like to get
confirmation of that before I build my converter. Thanks, Doug - k4cle.

Hi group.
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 timebeacon at gmail.com
Thanks,
