Hi,
I don't understand that comment, nor how you are getting such "clear" spectrum analyser results in your other thread.
The whole point of the 433 MHz ISM band is that transmitters can (or even should) use the same frequency and the different "messages" (data packets) are discriminated by time sharing. Each transmitter should only transmit the radio signal for a very short period of time, which is why I'm surprised that you are getting such a detailed spectrum graph.
Have you modified the Weatherduino boards (or program) in some way so that they are transmitting continuously?
Cheers, Alan.
