I need to send and receive coordinates in NMEA format from a VHF radio to a computer. Any suggestions where to look in order to accomplish this task? The transmission will occur only when the user presses the PTT button. Thank you all.

In amateur (licensed) radio, this is routinely done using APRS, which you might research. It involves an interface from the radio to the PC, including a TNC (Terminal Node Controller). I suppose there is no reason it couldn't be adapted to non-licensed VHF frequencies. More detail about your need would enable me to help you more.

I already have licence for some frequences and I would like to use those. Could this APRS system run on my frequences? So I Have some stations that I need when they press the radio and only in the start of the press to transmit to a central station and not interesting for the others station , the gps coordinations! – Vagelism Sep 17 '12 at 15:52
