How to Use Your TH-D74 Programmer
The KRS-D74 Radio Programming Software is designed to make it easier to program your radio. Details of memory channels and other set menu options of your radio are in the program to access and study at your pace. No more “function key frustration” from trying to set options from the face of the radio.
Memory Channels Include:
Other Menu Item Categories Include:
The Radio Programmer Is for so Much More than Just Memory Management.
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.
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.
Limit Memories are used by the radio for Program Scan. Program the same details for Limit Memories as for regular memory channels. Many of the Limit Memories are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank.
The DR Channels are special memories of the radio used for quick manual D-Star setup from the radio’s face. D-Star channels do not have to be programmed here before being saved to memory.
Home/Call channels are special memories accessed through one button recall on the radio. These channels are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank.
The program makes available the same VFO’s as in the radio (usually one per band). Remember these are not real memory channels since the details are lost as soon as you tune the radio manually. There is no one button recall for these. You do not need to program into VFO before programming details into a memory channel. These channels are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank.
Ten NOAA weather frequencies are preprogrammed in the radio, and cannot be changed. Use this screen to edit Name, set Skip conditions and add a weather channel to a bank along with other memories.
Once stored in the radio during GPS operations, these channels are read from the radio with the other details.
Memories and D-STAR Columns
The TH-D74 handles D-STAR and FM memories in Memories. It is here in the Programmer that the D-STAR specifics for each channel are found. The D-STAR columns Become active once Operating Mode is set to DV or DR.
Set "My Callsign" to your FCC issued callsign.
Source and Destination
The D-STAR Calculator automatically sets up the Talk, Echo, Info and Unlink channels for your "Source" repeater. The "Source" is the repeater you access to begin your adventures. Just like with analog repeaters, you must be able to hit the "Source" repeater.
Route/Link to Repeaters
Now that you identified your "Source", let's set up your Destination. In D-STAR you can Link to Repeaters or Route to Repeaters. To set up channels that link or route, use the drop down at the top of the first tree to select your function, then select your repeaters by checking a country, region, state, city or individual repeater. A counter Below the list keeps track of how many you have selected.
Link to Reflectors
For even more fun, and a great way for a Beginner to get started, Link to Reflectors. D-STAR reflectors are a special type of Internet connected gateway that rebroadcasts each signal to all the other linked nodes or repeaters. Remember.. EVERYBODY is listening.. but that's what makes it fun. You have a whole world to talk to through your local repeater, "Source", linked to a reflector. To set up a channel that links your repeater to a reflector, check the box for that reflector in the Link to Reflector tree.
The resulting channels are set up and ready to go.
To Use these Settings for D-STAR Fun:

RT Systems Programmers interface with two 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.
Repeater Book Search
An Internet connection is required for this search.
An internet connection and subscription to the service are required for this search.
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.
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.
