As alicensed radio amateur, I think that if one hears a communication, they must not act on it. Taking that to stupid reasoning, if you hear on the police band that there is a speed trap, you are not to slow down 'cos you heard it on the radio!!
You must not tell others of the communication either. Dont know where that leaves a mayday!!
For info, I was operating with the Air Training corp on their frequency which is around 430. Mhz, also a downlink for a stellite radio amateur. As priority user I was LEGALLY obliged to tell the American Satellite to close down. ( I did not, I am not that stupid)
Enjoy and do not interfere with the communications.
Anyway in the next few years you will not be able to hear anything as they will all be digitallised to to spectrum shortage.
