ILocator Interface
The ILocator base class interface is implemented (through its derived interfaces such as IATSCLocator) on Locator objects that contain tuning information about the tuning space. The base interface is never used directly, but only through the derived interfaces that are specific for a given network type. Locator objects can be created dynamically by Guide Store Loaders that have the necessary information about the tuning space, or a default locator for a tuning space can be installed by the third party who installs the tuning space. In any case, applications never create or examine locators except in certain testing or debugging scenarios. All Locator objects also support IPersistPropertyBag.
In addition to the methods inherited from IDispatch, the ILocator interface exposes the following methods.
| Method | Description |
| Clone | Creates a copy of the Locator. |
| get_CarrierFrequency | Retrieves the frequency of the RF signal. |
| get_Modulation | Retrieves the modulation type. |
| put_CarrierFrequency | Sets the frequency of the RF signal. |
| put_Modulation | Sets the modulation type. |
