(GX1850GPS, GX1850GPS/E, GX1800GPS and GX1800GPS/E only)
Connect the SCU-38 cable to the coaxial GPS
ANT connector on the rear panel, then tighten
the cable nut (see illustration at the right).
NOTE: The SCU-38 External GPS Antenna is
always more preferred than the internal GPS
antenna.

8.5.7 Optional SSM-70H (RAM4) Microphone

The transceiver is capable of using an SSM-70H (RAM4) Remote Station
Microphone to control all the Radio functions. In addition, the transceiver can
operate as a full function intercom system between the SSM-70H microphone
and the transceiver.
Do not connect or remove the SSM-70H (RAM4) microphone while
the radio is powered ON. This may result in equipment failure.
1. Connect the Routing Cable (supplied with the SSM-70H) to the RAM
connector (eight pins) on the rear panel, then tighten the cable nut (see
the below illustration).
2. Install the two ferrite cores (supplied with the SSM-70H Remote Station
Microphone) to the routing cable or the CT-100 extension cable, then snap
the halves together. These cores should be installed near the connectors
of the transceiver and the microphone ends of the cable.
3. Attach the ferrite cores as close as possible to the plugs, as shown below.
