Cool!

What sort of radio do you use?

My friend and I tried to do -- the two of us in different cars driving down the same stretch of highway this with GPRS radios and very quickly we were not able to pick up the other's broadcast. We assumed it was that we didn't have big enough antennas and were not using a repeater.

Note - others were driving we were each a passenger in our respective cars.

Did you have car mounted external antennas? I'm totally new to the hobby so I might be wrong here, but I believe the handheld units are kinda trapped in a Faraday cage if you use them inside the car. If you have the 20W+ mobile (not handheld) kind and mount it to an external antenna though, there should be enough range even just with GMRS as long as you're not on the other side of the mountain or something?

Edit: Sorry, it's GMRS, not GPRS (facepalm)

We were not using car mounted antennas. We will try this next time!
