ROS on 27 Mhz

18 November, 2010

New ROS frequency for enthusiastic CB users

You need a SoundCard Interfacing to use ROS with your CB Rig. Some interfaces use a optocoupler to switch the PTT. The optocoupler output current is not enough for a lot of CB Rigs. You should use then the typical 2N2222 transistor or, if you want a complete isolation, use a reed relay.

On Rig Menu, set PPT via COM and select your Serial Port Number. Pin is usually RTS (according your interface).

To do test, you can active the ROS Beacon.
