Abstract

PURPOSE:To satisfy legal regulations for the receivable range, by making the tuning voltage of the lower limit frequency of the VHF high band lower than the tuning voltage of other bands. CONSTITUTION:Respective contacts of band change-over switch S1 are conncted to the band switching terminal of the tuner to apply a prescribed voltage while interlocking with the band switching operation. The contact inthe VHF high band side of switch S2 is connected directly to the costant-voltage power source through the half-fixed resistor. The voltage for band switching is divided by voltage dividing circuit 55 and is applied as a tuning voltage. By controlling half-fixing resistor 52, the upper limit of the tuning voltage at the VHF high band receiving time is regulated, and the tuning voltage is obtained which has the lower limit regulated by voltage dividing circuit 55.
