Video Description

In North America, UHF TV channels 70 to 83 never saw much use, but in 1985, Radio Shack introduced the Multiple Video Distribution System, which accepted three video signals and rebroadcasted them on channels 74, 78, and 82. In 1987, they were forced to take it off the market, due to the FCC reallocating the frequencies used by channels 70 and above for use by mobile phones and public safety services. Luckily, I was able to find one of these unique devices, and despite the FCC banning it 35 years ago, it still works great -- if you have a TV or VCR old enough to tune in those upper UHF channels! Correction: It can also rebroadcast sources on channel 2 or 4, not just channel 3. The resulting output channel will be shifted down or shifted up by one, respectively. #uhf #tv #vhs
