q
ANTENNA CONNECTOR [ANT]
Accepts a 50
Ω
dual band antenna with a PL-259 connec-
tor. (p. 14)
w
SPEAKER JACK [SP]
Connects a 4–8
Ω
speaker, if required. Outputs the se-
lected band’s audio.
e
DATA JACK [DATA]
6-pin mini DIN jack to connect a TNC, etc. for packet op-
eration.
NOTE:
The connection between this jack and the TNC
differs depending on whether 1200 bps or 9600 bps op-
eration is chosen in initial set mode (p. 63). See right
for pin assignments.
r
POWER RECEPTACLE [DC13.8V]
Accepts 13.8 V DC with the supplied DC power cable.

GMSK)

q
DATA IN
Input terminal for data transmit. See p. 63 for details on
how to toggle data speed between 1200 and 9600 bps.
w
GND
Common ground for DATA IN, DATA OUT and AF OUT.
e
PTTP
PTT terminal for packet operation only. Connect ground to
transmit data.
r
DATA OUT
Data out terminal for 9600 bps operation only.
t
AF OUT
Data out terminal for 1200 bps operation only.
y
SQ (squelch out)
Becomes high (+5V) when the transceiver receives a sig-
nal which opens the squelch.
• To avoid unnecessary TNC transmission, connect squelch to the
TNC to inhibit transmission when receiving signals.
• Keep audio output at a normal level, otherwise a “SQ” signal will
not be output.
