Abstract

PURPOSE:To cause the tuning range to meet standard requirements (DOC and so on), by raising the upper limit value of the tuning voltage only at the VHF high band receiving time. CONSTITUTION:Three tuning circuits are provided for the VHF low band, the VHF high band, and the UHF band, and tuning circuits and tuning voltages are switched while interlocking with the band change-over switch. Since upper and lower limit values of the receivable range in the VHF high band are regulated in DOC standards of Canada, half-fixed resistor 53 is controlled under the state, where variable resistor 51 is turned up to the upper limit, to regulate the tuning voltage, and thus, only the upper limit of the receivable range in the VHF high band is regulated effectively without influencing receiving of other bands at all. Variable resistor 54 is controlled to regulate the lower limit in the VHF high band.
