Hello netters,
I'm looking for information/schematics on how to make a GPS reciever.
It must be fairly simple to make and cost around $10.00 to build. :-)
Seriously though, I'd like it to be resonable in price. I want to build
one to use for making maps for orienteering and also to track myself
on excursions into the deep woods. There is nothing I can't handle
in the digital world but the world of high frequency analog is kind
of a mystery. Any help would be greatly appreciated.
Keith

I'm looking for any information that may be available via ftp on
AMSAT (specifically the new Phase 3D info, like frequecies,
capabilites, etc). Can some one tell me if this is available?
Thanks

To: ham-space@ucsd.edu
I've not been able to find much on portable Oscar 13
stations--ones that work well with little antennas
and low power. The QRP publications seem to focus
on the low earth orbit satellites.
I tried Mode S, 6 watts to a 5.5 ft boom 436 MHz
yagi and a 2 ft. dish with a 2.4 GHz feed, but
only made 6 contacts in 3 hours (1 hr/day).
Problem was, several stations had trouble hearing
my signal, even though it sounded fine to me.
I could sometimes hear myself clearly running
6 dB less power (1.5 watts).
Should I try Mode B or work on my 436 antenna?
I prefer small antennas I can stick in my car
without taking apart. Makes a big difference
when the weather changes for the worse....
