I bought a copy of the Official Star Trek magazine (the American version), and there was a full page ad for what looked like a rip-off of the BOSE Wave Radio. Made by Zenith it was a clock-radio device but could be tuned to TV frequencies - it claimed you could wake up to your favourite TV shows.
I guess they must broadcast NTSC signals at VHF levels? Either that or the radio encompassed a UHF receiver.
Sounded good though.
