Simplified Remote Control (Optional RS-BA1)
Remote base operation is made easy as the IC-7851 operating system
incorporates the remote base server software. A computer is not required in
the shack for audio or rig control. Up to three, unique user log-in/password
configurations are part of the internal server. As the rig control has a priority of
service, the controls will feel like you are right in front of your rig.
Optional RS-BA1 main features
• Most functions of your transceiver, including interference rejection func-
tions and IF filter settings, can be controlled. Also, received signal strength
and SWR can be observed on the computer display.
• Received voice recording function.
• Optional RC-28 USB remote encoder provides a hardware dial/transmit func-
tions for a realistic dial operation.
• The IC-7851 can wake-up from the standby mode through the RS-BA1 software.
