Mavericks arise! You have nothing to lose but your tracking devices!

Where, oh where, has my little dogie gone.

Bad doggerel, bad.

Try Furuno... I know they make some that are maybe 1/4" x 1" x 2" (6 mm
x 25 mm x 50 mm), connector for external antenna, 5.0 or 3.3 V, serial
output in standard ASCII formats.  I think it's logic serial and you
need to follow with a MAX232 or equal to get RS232 serial.  One antenna
I have seen used is a "puck" that is maybe 1/2" thick by 2" diameter (13
mm x 50 mm).

Where are you going to put a troll or spammer that they wouldn't come 
within the tracking error(say 20 meters in an urban canyon)  of a
working computer?

So how do the cows transmit back their position?  Or do they log 
the positions to see where the cows go when they aren't watching?

   I was thinking more along the lines keeping them at the bottom of the
Grand Canyon.

   You've got me.  I haven't been near a live cow in almost 39 years.  I
prefer my cows already processed.  In fact, there's some beef cooking in
my crock pot full of chili right now.

   I didn't start the part about the digital cows, I just commented on
it.

Can you give some more info on the ones you are using?

Thanks.

This has to be an opening for a 'Far Side' cartoon. ;-)

Have a look at the Lassen IQ module as sold by Step GPS in Oz.

3.3v at 30mA. Needs an active antenna (also from Step)
