The KRS-D74 Radio Programming Software is designed to give you the ease and convenience of programming the memories and set menu options of your radio from your PC. Any memory channel with all its details can be sent to the radio with a simple keystroke.

With the KRS-D74 Programmer you can begin a new “factory fresh” file into which frequencies and option settings are entered. Or, you can read from the radio, store these details on your computer and make changes. Then, with minimal button pushing, send the new configuration back to the radio.

The Programmer allows you to create and save as many files as you want for your radio. Files can even be shared between users via email or the Internet.

Managing all the options of this great radio becomes easy with the Programmer. The cut, copy, paste and insert features of the Programmer make channel management easier than ever.

Open more than one file at a time. Memory channel information can be copied from one file to another within the Programmer making it really easy to set up a new file.

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.

D-STAR Settings

D-STAR Settings

Set “My Callsign” to your FCC issued callsign.

The list of Your Callsigns is just storage. The callsigns used during a transmission are programmed in the memory channel. This list is available to make a selection from when working with DR Memories; callsigns do not need to be entered here first for Memory Channels.

Tx messages, name/location/equipment details, etc., scroll on the radio receiving your call. Be sure to turn on the Tx-Message with the checkbox.

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.

Talk - the CQ channel for talking with others.

Talk - the CQ channel for talking with others.

Echo - a test function that repeats your transmission back to you. Good for letting you know that you are, or are not, hitting the repeater.

Info - The function that triggers a status response from the repeater (i.e. linked to “where”... not linked)

Unlink - Disconnects the current link of the repeater (where allowed). More widely used to disconnect a link you establish. Remember... if you link, it’s always polite to unlink (hang up the phone) when you’re done unless someone has joined you locally. Then you might leave it to them to unlink.

The calculator sets up the same channels for a DVAP hotspot. You enter your frequency only once.

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 Repeaters

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.

Click Apply once to set up all these channels for the radio.

The resulting channels are set up and ready to go.

Your callsign, Rpt 1 Callsign and Rpt 2 Callsign are set automatically... No wondering which suffix goes where, or if it is positioned correctly. That is all done for you.

Name can be edited here to better identify the station. Name is what you see on the radio. It is not part of the D-STAR commands for use of the system. It may be all you have to identify the function of a channel. (Notice the frequency is the same for ALL these channels although they each do something different on the D-STAR network.) Make the Name something you understand.

The names are displayed automatically along with the frequency.

To Use these Settings for D-STAR Fun:

• Save and send the file to the radio.
• Listen on the talk channel.
• Be sure your call sign is registered on the system.
• Check repeater status on info channel.
• Check your connection to repeater on Echo channel.
• Link repeater to a connection of your choice.
• Talk on Talk channel.

Have Fun!

D-STAR Calculator for DR Memories

D-STAR Calculator for DR Memories lists repeaters worldwide for you to update or customize the list in the radio. Easily customize this list for places you plan to travel or places you want to work using a DR memory as your RPT2 repeater.

All repeater nodes are listed. Those the radio can use to transmit will be set automatically for “Repeater Use”.

Latitude and Longitude are included where that info is available from the source and the repeater is marked for use.

Click a country, region, state, city or individual repeater.

Use starting channel to replace or carefully add to your list.

No searching for data, it’s all right in the RT Systems Programmer.

The D-STAR calculator is updated automatically with the program. Just “Check for Updates” periodically to be sure you have the latest list.

Grid Display

• RT Systems now available in English, French, German, Italian, Spanish, Portuguese and Japanese.
• Set colors for text (Fore) or background (Back) of alternate rows for easier viewing across the columns.
• Freeze columns to keep information on the screen as you scroll to the right of the page.
• Hide columns you don’t use. Customize your printout: hidden columns do not print.
• Use Combo for Check boxes – changes the grid to eliminate check box selections that are disabled on some systems.

Memory Defaults

• Set options to control auto fill information for memory channel entries.

Font

• Set options to control the font in the column headers of the channel entry screens. Select any font and font size available on your computer.

Other

• Set options to control how the programmer handles the global Radio Menu Settings file.
  • Separate (default) handles the global settings of the radio in a “set and forget” fashion. Once you set these up and save the file you won’t have to reset them for a new frequency file.
  • Together as one gives you the ability to create files that are complete with frequencies and customized global settings. In this mode, each file begins with factory defaults for every option of the radio.
• Check “Get data from Radio” new file option to prevent data loss when you read from your radio into the programmer.
• Check “different window” option to make the programmer for a different radio run in completely separate window rather than in a separate tab of the same window
