1) ANTENNA 1 -
This connector is the antenna input/
output of Transceiver ‘A’. Attach a 50 Ohms nominal
impedance coaxial feed line from the antenna. Ensure
that the connected antenna is resonant in the 144 - 148
MHz (2-Meter) range prior to transmitting. This connector
accepts a standard PL-259 plug.
2) ANTENNA 2 -
This connector is the antenna input to
Receiver ‘B’. Attach a 50 Ohms nominal impedance
coaxial feed line from the antenna. This connector
accepts a standard PL-259 plug.
3) Interface RS-232C -
This 9-pin DB-9 connector provides
a standard RS-232C interface to a dumb terminal or PC.
Refer to the COMPUTER CONTROL section of this
manual.
4) FAX/DEMOD -
This RCA connector is an audio input for
CW, RTTY, HF/FAX, or WEFAX encoded signals that are to
be demodulated by the optional DEMOD270 demodu-
lator module. Input impedance is a nominal 600 Ohms.
Provide a nominal 250 mVolt signal level for proper
operation.
5) EXTERNAL TNC -
This is an 8-pin DIN connector for an
optional external TNC. Refer to the TNC's Operation
Manual for wiring information. The pin numbers and
