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 15 Amperes (continuous duty). Make certain that the
red lead connects to the positive side of the supply. The fuse is 25 A (USA/
Asian version) or 20 A (European version).
ANT Coaxial Socket
Connect a 144-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 de-
signed specically 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 lev-
el 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.
