I wrote a serial interrupt handler that catches an ID-string of 2 bytes.
The problem I encountered is that when there is no carrier wave (no transmitting), the data output of the RF receiver produces
noise transitions at CMOS level (from 0 to 5V and vice versa). The RF module has no way to switch off this noise.
This is causing a relay periodically switching on and off.

You mean, that the micro is erroneously interpreting the noise as being the correct ID-string, from time to time, which makes a relay switching on and off?
