RT Systems Programmers interface with sources of data to make it easy for you to find repeater information. Some of these sources even include information for repeaters outside the US. Your existing subscription to a service (where required) works in the programmer.

• RadioReference Search – This database has commercial and amateur repeaters. A subscription through RadioReference is required to access this data.


• RepeaterBook Search – This database contains domestic and international repeater listings. It is free to use from within the programmer.


• Frequency Lists– Convienient lists including weather, FRS and GMRS frequencies to save you from having to search elswhere for them.

Radio Reference Search

An internet connection and subscription to the service are required for this search.

Enter the user e-mail and Password that you established when you purchased your subscription from RadioReference.

Then select the State– Select the state from the list and County– Select the county from the list to get repeaters for that area. Click OK.

Repeater Book Search

An Internet connection is required for this search.

Search by country/state/county or narrow your search to your area.

In Area Search enter your zip code or town and a radius to get repeaters that you will use more often.

Select Amateur and customize your search by Band and Modes that fit your radio.

Frequency Lists

Choose from this list the frequencies you want to add and the start channel for them.

The information is returned on a screen that is not yet ready for radio programming, this screen lets you examine the data to see if the results are about what you expected. You might find that you spelled the city name wrong which resulted in nothing being returned; or that you want to pull repeaters from further away; or you want to get repeaters for different bands.



Select what the radio uses as the Name display. You can select the Callsign (default), City, State, Region, Repeater Notes or Sponsor. Notice that each of these categories is a column of information in the grid. You will see those names at the top of the screen. You are selecting the information in that column for the Programmer to set up for the Name field. NOTE: The radio will truncate (cut off) the information in the field at the maximum number of characters it can use for the Alpha/numeric display. You might end up with only the first four or six characters of the information in the column. Consider this when selecting the information.

Select what the Programmer will use in the Comment field. This information does not go to the radio but can be very helpful for identifying a channel as you work with it on the spreadsheet. You can print this information along with other details for the channels to have it on hand as you travel. Again, select Callsign, City, State, Region, Repeater Notes or Sponsor.

Sorting Return Data

The screen that opens after you click OK for one of the external data searches gives you the ability to remove repeater information that your radio cannot use. You might have a radio that does not do DMR, DStar or Yaesu Fusion. Simply uncheck these in the list. The channels are removed from the list automatically.

Once you finish eliminating frequencies or modes your radio cannot use, select your radio from Modules and then click Create file for (your radio).

Resulting File

After clicking Create File for (Your radio) the programmer creates the file that you use to program your radio. Notice that all the Tones are set up with the tone frequencies. All done automatically.

What a list and all you did was enter a location!
