I use a T5720. How can I use it to send data over it ? thanks Arshad
Create your own protocol .. try to see how wide is the channel and then try some solution like sending pulses in morse code whith location .. or translate nmea protocol into pulses .. the thing is u will need some kind of device made speciaally for your need's .. I don't known if it's possible to send data whith an old modem 33 kbps or less .. it depend's on the bandwith of the channel but that's an other option ...but it'll hace to be half duplex and the talk/no talk action will be hard yto implement .... a verry simple option is ..... a code at the beggining .. s eries of pulses separated in thime so that the machiine knowns the truck is triing to communicate .. and then send each numbres of the lat and long. in pulses ...a specific time .. it's slow and noise sensitive but it's something ...

Those radios were not designed to transmit data, and has no any port for it.

thanks Neto.
Can you recomend a solution for GPS tracking over VHF radio for about 10 vehicles covering 100 Kms ? The vehicles already have Motorola GM338 (25W VHF mobile radio).
Thanks
