Hey all.
I've done some searching for the last few months and am looking for advice. I have a little personal project I'm trying to throw together, but i'm entering unknown territory. I'm looking to transmit (+4km) 15-20 charactors to a transceiver and return similarly sized data back. Each character is 8 bits. What would be the "best" way to do this? I've looked into everything from VHF to 9GHz freq, AM and DTMF coding. I'm at a loss. Its going to be on a person and must not require a license. Heck, I've even played with Citizen Band (CB) radios with DTMF. I need long range, low power use, and moderately fast data rates (1-10Kbps). I'm using PIC processor for data management.
Any advice?
Damon
