A writing method for an optical disc to optimize a writing speed, wherein a spiral track on the optical disc is divided into a plurality of zones, and different CLV writing speeds are used for performing a ZCLV writing to the zones respectively. The writing method comprises steps of: setting a plurality of writing modes; storing a plurality of zone parameter sets for the writing modes respectively in a memory, wherein each of the zone parameter sets comprises dividing times for dividing the zones, and the different CLV writing speeds for the zone respectively; determining a disc type of the optical disc by a disc type determining device before the ZCLV writing is performed; selecting one of the zone parameter sets that is suitable to the disc type of the optical disc; and performing the ZCLV writing with the writing mode corresponding to the selected zone parameter set.

A multi-bit program identification signal is transmitted in the audible band with a program signal, and a receiver detecting the program identification signal automatically sets a predetermined minimum volume for reproduction of the program information. The volume control circuitry at the receiver can be made responsive to any one of a plurality of different program identification signals.

A superheterodyne receiver in which unwanted lowering of the RF gain due to the presence of an interference signal outside the band of the desired signal is substantially eliminated. Levels of the outputs of both the RF amplifier and first mixer of the circuit are detected. The two level detection signals so produced are summed, and the sum signal applied to the gain control input terminal of the RF amplifier.

An antenna switching circuit which selectively transmits, to a receiver, RF signals from a plurality of antennas including RF signals of different frequency bands such as the VHF band and the MF band using a single output terminal. To prevent a level drop of RF signals of one of the frequency bands due to a common use of the output terminal, a unidirectional switching element is added to a switching circuit network by which the selection of RF signals from the different antennas is performed.A branching circuit for separating RF signals of different frequency bands is provided with an attenuation operation using a variable impedance characteristic of a semiconductor switching element which is basically on-off operated for the switching between the RF signals of the different frequency bands.
