I need to transmit a string of message between two Radio frequency transmitter. The message will be stored a microcontroller (e.g. 8051). How to go about writing a program for it and how to interface between the micrcontroller and the transmitters. I am still an amauteur when comes to embeded programming. Any source code or info on this ?
If you want a one-watt radio but don't want to pay the killer prices that some companies have to offer, check out MaxStream's new 9XTend. This wireless radio modem has a full one-watt of power (not pseudo-conducted one-watt trash like some other companies). This allows for up to four watts conducted output which is still allowable by the FCC without a license. MaxStream claims that you can get up to 40 miles of line-of-sight range with a high gain antenna. The development kit costs like $500, but since it is new the price will probably come down. Everything that I have read about this new radio sounds like MaxStream knows what they are doing. You can see their stuff at http://www.maxstream.net.
