Hi Paul, no need to shout :-)
I think the device you are referring to was a device which fitted on the audio
output, which was able to differentiate between speech and FM noise. Fed with
FM noise it would disable the output, but open with the presence of speech. I
once briefly heard one in use and it seemed to work quite well. Sorry I have
no more details than this.
