RT Systems Programming Software for the Explorer QRZ-1

The programming process begins by first installing the program then installing (and allowing) the drivers for the cable. Be sure to complete both of these steps.

Next, make all the connections between the radio and the computer and complete Communications | Get data from radio. This “syncs” the radio and computer. Even if the radio is not yet set up with memory channels, there are details that the programmer needs to get from the radio.

Start setting up details for your radio in a “factory fresh” file (File|New) or in the file that was created when you did Communications | Get data from the radio. Begin by entering a receive frequency (that will be the frequency published for the repeater). When you press Enter or Tab to leave the Receive frequency field, the program will complete details for the channel. Then customize Name and Tone to match the details you have for that local repeaters.

Use the links to external data sources (File | External data) built right into the programmer to access repeater details for your area or for a location you plan to visit. Then with just a few button clicks, you have a file with hundreds of entries and all you typed was your location (i.e., zip code or city).

Save your file as you work. This is a computer, after all, and you would hate to lose your work should the system fail. Actually, create and save as many files as you want or need. You could have one file for home, a different one for the vacation house, another for the trip to your son’s house, another for the yearly 3K run and picnic where you help direct traffic and want the radio to be programmed with only the frequencies for that event. Remember, radio programming is an overwrite process. Everything in the radio is replaced by everything in the file.
