Abstract
In recent years the FCC has, through legislation, placed increasing requirements on television and tuner manufacturers to provide tuning of both VHF and UHF channels on an equal basis together with a means of indicating the exact channel number. FCC Part 15 Regulations state, "If any television receiver is equipped to provide repeated access to UHF television channels at discrete tuning positions, the manufacturer shall provide for the display of the precise UHF channel selected or shall provide to the user a means of identifying the precise channel selected..." In applications using varactor VHF/ UHF tuners with all electronic channel selection, there is no rotary shaft on which to fasten a channel indicator dial. Some means of channel number display other than mechanical is then necessary.
