The Proximity Search allows you to search for repeaters near a town or landmark. You can select a radius (or distance) from the search location and all repeaters within that radius will be included (it's actually a box that is created).
You can search for a maximum of two bands at the same time or for a repeater with a specific frequency. You can also filter by repeater call sign, feature, or operational status. You can narrow to repeaters that are listed as “Open” only.
Finally, you can select the default sort type of the output.
