Final answer:
DSC operates on VHF Channel 70, which is used for distress, safety, and calling, while VHF TV channels occupy the frequency ranges of 54 to 88 MHz and 174 to 222 MHz.
Step-by-step explanation:
The question you've asked pertains to Digital Selective Calling (DSC), which is a standard for sending digital messages via the Very High Frequency (VHF) marine radio system. DSC operates on Channel 70, which is a channel specifically allocated for distress, safety and calling purposes. Television channels, in the context of VHF, utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz, with the entire FM radio band lying between channels 88 MHz and 174 MHz. The VHF TV channels carry both visual and audio information, necessitating a larger range of frequencies than what is needed for simple radio transmission.
