DX/Local
DX is the normal operational mode. Local mode can effectively limit any inter-modulation and/or
interference in a busy RF environment. This is done by limiting the amount of RF gain in the receiver.
When local mode is selected, the range of the receiver is compromised. Depending on your application
and environment, Local mode may be necessary for better performance. DX mode is default.
