I need a design to transcieve RS-232 data from a Laptop to a PIC system. I am quite clued up with digital electronic systems, but have a scant knowledge of RF communications systems. The reason for these frequencies is the availability of antenna's and hardware for CB's. (26Mhz here in NZ) Parallax Inc have several Serial Transcievers designed for use with their BASIC Stamp products, but the prices are out of my reach and I don't see any reason why I can't make my own...
- Baudrates need to be at least 2400, asynchronous.
- Range needs to be at least 100m line of sight. Supply power for longer range is not a problem.
Unfortunately I don't have a clue as to where I should start, so I'd really appreciate it if someone could push me in the right direction. A link to information and specifications of RF digital transmission or whatever.
Thanks
