5-9. Beep

The beep signal is generated using the timer in the micro-

computer. A dot lasts about 40ms, a dash about 120ms. The
oscillation frequency is about 1.4kHz.

5-10. PLL and DDS control circuit

The TK-80 has one PLL and two DDSs. The main micro-

computer outputs frequency data to the PLL and DDSs seri-
ally according to the display frequency.

5-11. TX-RX unit control signal circuit

The microcomputer sends the mode signal, IF filter select

signal, power signal, band-pass filter signal, MIC gain, and
CAR level data to the TX-RX unit. It receives meter signals
and standby switch signals from the TX-RX unit, displays data
on the meters, and performs the transmit operation. The
output signal from the microcomputer goes to the serial-to-
parallel converter IC16, IC15 and IC10, D/A converter IC13
(Fig. 14).
