What technique allows commercial analog TV receivers to be used for fast-scan TV operations on the 70-centimeter band?

The 70-centimeter amateur radio band spans from 420 MHz to 450 MHz. This frequency range happens to perfectly overlap with standard analog cable television channels 57 through 61. Because of this overlap, an amateur transmitting analog Fast-Scan TV (FSTV) in the 70-centimeter band can simply align their transmission frequency with one of these cable channels. Anyone with a standard, off-the-shelf cable-ready analog television can receive the signal by connecting a 70cm antenna and tuning the TV to the matching cable channel. Distractors involving satellite dishes or Channel 2 are incorrect because Channel 2 is in the VHF band (around 54-60 MHz), far below the 70cm band, and satellite equipment operates on entirely different microwave frequencies.
