I am programming two stamps, one connected to a rf transmitter, the other to a rf reciever. I have written the code to send a string of text entered by the user (this part works). However, on the reciever side I am unable to recieve the string. I am able to send one character at a time with a WAIT to determine valid text from garbage. But some characters are getting dropped. I have slowed down the transmission to one character ber second. Are there any tricks or tips with transmission of data over RF?

Without built in handshaking I'm not certain. Maybe you can poke around http://courses.ncsu.edu/ece306/ and find something there. Doubtful though, but it does talk about how to do serial communications, which I would think would be the basis for the Stamps, though I've never used them, just read up on them.

modulation and error correction is key.

What coding scheme are you using?

Simple "one-on-one" coding is bound to be errorprone.

You need lesser symbols in your code to be efficient over RF.
