There has been a lot of concern lately about the FCC and Lightspeed's new
service that is very close to the GPS frequency. Apparently, the FCC is
leaning towards allowing the service even if a lot of older (and less expensive
current) GPS receivers are interfered with.
It would be very unfortunate if the Austron units ceased to work if this were
to happen.
Does anyone have a handle on this issue?

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 timebea...@gmail.com
Thanks,
