Also rotates while receiving depending on the setting in
FUNC set mode (SET).
(p. 101)
e DATA JACK [DATA] (p. 57)
± Connect a PC through the optional data communication
cable OPC-1529R, for low-speed data communication
in DV mode or data cloning with the cloning software
CS-80/880 (free download).
± Connect a GPS receiver through the optional data com-
munication cable OPC-1529R, for GPS operation.
r PACKET JACK [PACKET]
(pgs. 120, 121)
Connects a TNC (Terminal Node Controller), etc. for data
communications. The receiver can support 1200/9600 bps
packet communication
(AFSK/GMSK).
t EXTERNAL SPEAKER JACK [SP]
± Connects an 8 Ω speaker.
• Audio output power is more than 2.0 W.
± Connect an optional cloning cable OPC-478UC or OPC-
474 for data cloning.
y POWER RECEPTACLE [DC13.8V]
Accepts 13.8 V DC ±15% with the supplied DC power
cable.
NOTE: DO NOT use a cigarette lighter socket as a
power source when operating in a vehicle. The plug
may cause voltage drops and ignition noise may be su-
perimposed onto transmit or receive audio.
ANTENNA INFORMATION
For radio communications, the antenna is of critical impor-
tance, to maximize your output power and receiver sensitiv-
ity. The transceiver accepts a 50
Ω antenna and a Voltage
Standing Wave Ratio (VSWR) of 1.5:1 or less. High SWR
values not only may damage the transceiver but also lead
to TVI or BCI problems.
