N4PY publishes rig control software that is compatible with the AT-200PC

2

. Operation with this

software is shown here as an example of this class of program. To use the software with the tuner,
you will connect your rig to your PC via one serial port (COM1 for example), and the tuner to a
second serial port (COM2 for example). After launching the software, select the

Settings

menu,

then go to the

Preferences 3

menu. Check the box labeled "Using LDG AT-200PC Autotuner",

and select the appropriate COM port from the list.
