Mick - had thought of that, only problem is that 96 are the competition to the radio station we're using so they may be 'reluctant' to assist. From what little info I could garner about their set-up they use some kind of transceiver which feeds back to the studio, via and aerial on the roof (of the radio station). Someone also thought that something was suction-attached to the window of the a/c for transmissions
