13.8V DC Cable Pigtail
This is the power supply connection for the transceiver. Use the supplied DC cable to
connect this pigtail to the car battery or other DC power supply capable of at least 11
Amperes (continuous duty). Make certain that the red lead connects to the positive side
of the supply. The fuse is 15-A.
ANT Coaxial Socket
Connect a 430-MHz antenna to this type-M (SO-239) socket using 50-Ohm coaxial
cable and a type-M (PL-259) plug. Make sure the antenna is designed specifically for
use on the operating frequency.
EXT SP Jack
This 2-contact 3.5-mm mini phone jack provides receiver audio output for an optional
external speaker. The audio impedance is 4 Ohms, and the level varies according to the
setting of the front panel's VOL control. Inserting a plug into this jack disables audio
from the transceiver's internal speaker.
