Tested the Picaxe ERF modules using serial data and managed 400m from Tx to Rx across water. Best range is with the 868.3mhz as I tried different frequencies , but obviously need proper aerials for the 433mhz etc. Great little units.

Could you help me write a very simple program that uses 2 ERF modules. I just want the transmitter module to be used to switch on an output connected to the receiver module. I am using 2 x 08M2 chips.
