I’ve never done this. I know it can’t be legal – is it? This is only a wild brainstorm to see if any one has tried it or is thinking of doing it.

The thought came to me that one can still get North American analog cable TV channels (Hyperband) 63 and 64 and they have audio channels that are very close to FRS/GMRS walkie-talkie frequencies. I was wondering if someone where to solder in a F-Connector-RG59U cable to the antenna output of a FRS/GMRS unit, employ a battery eliminator power adapter to avoid battery drain with holding down PTT, use a cable splitter to enter their cable TV service, and connect the W/T to the analog cable service in their house; what would happen if they tried to do a QSO across town with a partner using a similar W/T on same FRS/GMRS channel? That may work as the cable company probably is not bandpass filtering this frequency range (UHF 460-467 mHz).
However, if the W/T audio on your cable TV set was off-frequency a bit can you make your cable-ready TV or cable box detune a bit to pull it in? Probably not. Or would changing the W/T frequency help? Maybe not. The frequency on your cable TV box for audio on channels 63 is 461.75 mHz and 64 is 467.75 mHz. FRS/GMRS is from 462.5625 to 467.725 mHz. Audio channel is FM just like the W/T’s. The FM audio bandwidth on the TV is a bit large so it may be able to pickup all narrow bandwidth W/T units just fine – no matter what FRS/GMRS channel set to.
If any of this works could this be a alternative cable TV pirate broadcast medium for your town or community? Cable companies are usually per-town/city monopolies. Meaning this would NOT work statewide or national – only within your community or town. The cable company may not find out about it if they don’t already have programming on analog 63 or 64. Its worth an experiment for the brave of heart – or not…
