1 DC 12 V IN This is the 13.8-volt DC power
connector. Be sure touse a coaxial-type barrel plug.
A regulated power supply capable of providing at
least 2 amps is recommended. Be sure to observe
proper polarity and ensure that the center conduc-
tor is wired
+
(positive) and the outer conductor is
-
(GND).
2 CAT This 6-pin DIN plug allows external
computer control of the FRG-100 when used with
the optional FIF Interface and software. See the
CAT Control System chapter for details.
3 EXT SPKR
This 2-contact mini phone jack
provides receiver audio for an external loud-
speaker with an impedance of 4
-
16 Q. Inserting a
plug in this jack disables the loudspeaker.
4 REC This jack provides a constant level (100
mV
@
IkQ) audio output, which is umfected by the
VOL control. This audio can be used for recording
purposes, and for connection to data demodula-
tor/decoder equipment.
5 REMOTE Use this jack to remote control an
external tape recorder. When receiver squelch
opens, this jack goes to ground, closing the circuit
to activate a tape recorder or other device.
6 MUTE If using the FRG-100 with a trans-
ceiver, shorting this jack during transmit will mute
receiver output and attenuate RF signal input.
Check with information provided with your par-
ticular transceiver for proper connection.

7 ANT LO-Z Connect the 50
Q
coaxial feed line
to your low-impedance antenna here using a type-
M (PL-259) connector. See the Antenna Considera-
tions chapter for antenna types and installation.
8 BACK UP ONIOFF This switches the lithium
memory back-up battery. It normally should be left
in the ON position.
9 ANT
HI-Z
Use these spring-loaded terminal
connectors to connect a high-impedance antenna.
10 GND Connect this terminal to a quality earth
ground. See the Xeceivw Installation chapter for de-
tails on grounding.
