E2B08

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

  • A.Transmitting on channels shared with cable TV (correct answer)
  • B.Using converted satellite TV dishes
  • C.Transmitting on the abandoned TV channel 2
  • D.Using USB and demodulating the signal with a computer sound card

WhyCommercial analog TV receivers can be used for fast-scan TV on the 70 centimeter band because part of that band overlaps frequencies shared with cable television. Because part of the 70-centimeter amateur band overlaps frequencies also used for cable television, an amateur fast-scan TV signal transmitted on one of those shared channels can be received directly on an ordinary, unmodified commercial cable-ready television, answer A. Converted satellite dishes, the long-abandoned broadcast channel 2, and computer sound card demodulation of a USB signal are all unrelated techniques that don't apply to receiving fast-scan analog TV this way.
