Information from External Data Sources
Last Updated: 08/25/2014
The RT Systems programmers interface with four different external data sources: ARRL TravelPlus, Radio Reference, Repeater Book and RFinder Worldwide Repeater Directory. Access to this data is controlled by those who publish the data.

ARRL Travel Plus is purchased separately in addition to the programmer. It's advantage is that it can be installed and no Internet connection is required to access the data.

Radio Reference requires a subscription. This database contains more information on commercial frequencies.

Radio Reference is a free service.

RFinder Worldwide Repeater Directory is the more complete worldwide listing. A subscriptions is required to use this listing.
