I disobeyed the group suggestions about antennas, and bought one of the 
one which needs power.

I had asked whether I should apply 5 volts to the.

tom posted on his fine info page a pinout, which I'm going to use.

Pin 1 is 3-5.5VDC Antenna power input.
Pin 2 is Prime Power input
pin 4 is Backup Power input.
Pin 8 is GND

I am going to apply 3.3 to 1,2, and 4.  Just wanted to get an opinion 
before trying it.

I'm curious if somehow the suggested Primary and Backup power was all 
that was needed, or how you guys were getting your GPS signals in.  Are 
your antennas not powered?

thanks
Jim
