What technique allows commercial analog TV receivers to be used for fast-scan TV operations on the 70-centimeter band?
Transmitting on channels shared with cable TV✓پاسخ درست
Using converted satellite TV dishes
Transmitting on the abandoned TV channel 2
Using USB and demodulating the signal with a computer sound card
توضیح
The 70 centimeter band lies inside the frequency range that North American cable systems assign to their upper VHF-range channels, so a cable-ready analog television set switched to cable input and fed from an outdoor antenna tunes common ATV carriers directly. Channel 2 is far below this range, satellite dishes and sound card decoding solve different problems.
