The signal is received by the receiving section (6), and is configured as shown in FIG. In the gX4 diagram, (6) is the AF intensifier, (7) is the modulation circuit, +81
Vi output circuit transmits the output of the microphone (9) through the antenna (4) as a signal with frequency fB (60MB2) to preheating (2), and transmits the output from preheating (2) to frequency fA(
70-T MHz) is received through the antenna (4), the front end (lO) and the AF amplifier (111
After converting the frequency and amplifying the signal, the speaker Q21 emits the c-d audio. The state is the channel change button, when you need to change the frequency channel, close the manual switch and operate the channel change signal generator (+41) to generate the channel change signal (
For example, 20 KHz) is generated and sent to preheating (2).

Hitoshi is the AF amplifier, N6) is the modulation circuit, (2) is the output circuit, and the output of the microphone is passed through the antenna (+9)' and output as a signal at the frequency (70,7 MHz). Send to. 9) is a call button, and when calling the machine (1), manually close it and press the call signal generator +301'
The r-off operation generates a calling signal (for example, 1 OKHz) and transmits it to the machine fi+. (3I) is a channel change signal detector which detects the output (20 KHz) signal of the channel change signal generator of device (1) and inputs the channel change signal to the PLL synthesizer. PLL syntt
For Izaso, the numerical value N is determined by the input of the channel setting section (83) and internal settings, and the output fA =
Nxf8 occurs. Also, depending on the channel change signal, the CPU etc. changes the numerical value to N+1, N+2, etc.
If we make N+n, fA=N X fs ten n X f
B occurs when n=1.2. This makes it possible to change channels sequentially.
