    Abstract: PURPOSE:To cause a receiving frequency to agree with the tuning point by changing the receiving frequency step by step to detect presence or absence of broadcast. CONSTITUTION:When up switch Su is turned on, counter 31 starts counting, and the receiving frequency is increased by steps of 9kHz. When broadcast is received, output Q51 of FF51 becomes 1; and when broadcast cannot be received, output Q37 of detection circuit 37 becomes 0, and output Q51 becomes 0 also by next pulse Q32, and meanwhile, counter 31 is switched to a down-count mode. When the count value of counter 31 is reduced by 1 and the receiving frequency becomes the frequency for receiving again, output Q37 becomes 1, and output Q53 becomes 1 by the next pulse Q32, and FF circuit 36 is reset to complete tuning.

    Abstract: PURPOSE:To eliminate trouble of channel selection by making it possible to switch automatically a receiving broadcast to an optimum broadcast when the receiving level is lowered in the receiving time of broadcast of a certain broadcast station. CONSTITUTION:Signals indicating receiving levels are obtained for every receiving frequency from detection circuit 21 according to change of receiving frequencies and are converted to digital signals Qd and are supplied to comparator circuit 35. Receiving level Qm before change and Qd are compared with each other, and Qd is written in memory 34 in case of Qd>Qm. When memory 34 becomes a write mode, value n of counter 29 at this time is written in memory 33, and value n for broadcast of the maximum receiving level is written in memory 33. Then, the output of timer circuit 23 is obtained at every fixed time, and another station is received in case that the level of this station is higher than the receiving level of the current receiving station by movement of a vehicle, etc.

    Abstract: PURPOSE:To make it possible to select a channel by setting easily the dividing ratio of the programmable divider of a PLL frequency synthesizer with the constitution simplified by providing a frequency counter counting the oscillation frequency of a variable frequency oscillator. CONSTITUTION:The PLL frequency synthesizer 20 is equipped with reference frequency signal generating method 22, programmable divider, phase comparator 13, and switch 94 which feeds the output of comparator 13 back to the 2nd variable oscillation frequency element of local oscillator 8. In addition, this is provided with the method (composed of switches 94 and 95, resistors 96 and 97, power supply +B, etc.) which cuts off the feedback path of synthesizer 20 at the channel selection time and then supplies a constant voltage to the 2nd variable oscillation frequency element of oscillator 8, frequency counters 44 to 46 which are supplied with signals of a frequency relating to the oscillation frequency of oscillator 8, and latch circuits 50 to 52 which set the dividing ratio of divider 10 of synthesizer 20 corresponding to the frequency read by counters 44 to 46.

    Abstract: PROBLEM TO BE SOLVED: To easily discriminate deterioration in communication state at a radio telephone system composed of a digital line. SOLUTION: Concerning a digital radio telephone system for performing communication by setting the digital radio telephone line due to the radio communication of digital data with a base station, this system is provided with a quality detecting means 31 for the line and an output means 33 for a signal such as an oscillated sound accompanying the deterioration in line quality. When performing speaking through the base station b setting the line, when the quality detecting means detects the line quality deterioration, the signal outputted by the output means 33 is superimposed on an audio signal for speech to be transmitted to the base station side at least and deterioration in the line quality is informed for a speaker on the opposite side.

    Abstract: PURPOSE:To easily and appropriately perform the adjustment of the modulation factor or the output level, etc., of a transmission signal by providing a memory connecting part which can freely load/unload a memory component from the outside, and using the memory component to be loaded on the memory connecting part at a state where digital control data is written. CONSTITUTION:At a step where assembling in a manufacturing process is finished and the adjustment of every part is applied, an aperture part 24 formed on the upper half body 20a of a cabinet 20 is opened, and a memory 32 is packaged on a memory connector 34. Integrated digital control data Dat is written n the memory 32 in advance, and after the memory 32 is packaged the memory connector 34, a control unit reads out the integrated digital control data prior to that a transmission state is taken when a transmission operation is performed, and appropriate modulation factor and output level are provided.
