Timothy - I am really not sure - I cannot see why not though. I don't think that the code/library has anything to do with at what frequency the transmitters and receivers are working. I'd give it a try though. I really did very little changes to the example code provided with the VirtualWire.h library (pdf).

Does your code work for a transmitter receiver pairing at a higher frequency maybe 2.4 Ghz?

I do think that might work (I have not tried) – but if I understand things correctly, the VirtualWire.h library created by Mike McCauley has error protection in it to check if the message received a good message or whether it is just noise. This is the first thing I have done with RF and the Arduino – I’m curious to know if what you suggest does work though!

Couldn’t you just connect the transmitter/receiver to the serial pins on the arduino and use the default arduino library to handle data flow? Or use the SoftwareSerial library if you want to still have access to serial for PC connection?
