Connecting an explorist to a radio

[ossumguywill]

I heard that you could connect a gps device to a radio via nmea serial and have it transmit your location, and you can pick up other's location. If this is true, how is it done?

Unless your radio is expecting it, it'll be a lot of work.

Here's an example: http://www.icomcanada.com/products/marine/m504/m504.htm

 

Of course, some FRS portable radios have GPS built in.
