12. This Circuit Groups Inputs panel permits you to define terminals at the distant end of up to eighteen circuits, with each using your station as the local transmit terminal. An unlimited number of circuit group files may be saved and recalled. You can define new circuits by selecting a new receive location from the database, but there is an easier way. After clicking on the "Auto Define" checkbox, you can then go to the Circuit Analysis screen and automatically add circuits to the Defined Circuits list. Each time you move the Rx Dot to a new location, you have the opportunity to name the distant end of the circuit. This feature is very useful in contesting, where you want to quickly set up circuits to various target areas to see when the bands might open to those countries.
