Joe, There is a FREE program that monitors your serial port .. the program is at: http://www.serial-port-monitor.com/free-serial-port-monitor-downloads.html <http://www.serial-port-monitor.com/free-serial-port-monitor-downloads.html> This program simply MONITORS the serial port that you have opened with DXbase .. such as your rotor control ... I used this FREE program when I was trying to setup my radio interface ... The interface wil be able to TELL you what is being sent via the serial port 73 Joe wa6axe Joe Young wrote: > I have an RT-21 controller here that functions as it should on another logger.
