Using the JAWS Scripts For OpenGD77CPS and Compatible Software
Doug Lee
Last Revised July, 2026

This Guide provides tips for using OpenGD77CPS and compatible software with JAWS For Windows and these scripts. When the scripts are installed and a compatible application is open and focused, this document can be opened via a double press of JAWSKey+F1 (or Insert+F1).

These scripts officially follow the OpenGD77CPS code branch but also endeavor to support the older AccessibleGD77CPS versions and other older application incarnations. These scripts should load when an application by any of several known names is running. See System Requirements For JAWS Users for the names supported.

System Requirements For JAWS Users

These scripts require JAWS 2019 or later. They also require that the application name be one of the following:

• OpenGD77CPS.exe (current name as of this writing)
• AccessibleGD77CPS.exe (the older fork by Joseph Stephen)
• dmr.exe (the original Radioddity name)

Script Installation Instructions

To install these scripts on a new system:

1. Install JAWS if this has not already been done. This will require administrative privileges on the computer.
2. Run JAWS as the user for whom the scripts are to be installed. This and the following steps must be performed for each user of the computer who will be using JAWS with these scripts.
3. Download and run, or run directly, the installer for these scripts; and follow the on-screen directions. Be sure to install the scripts in the currently running JAWS version if a JAWS version list is presented.
4. To verify successful installation, type Insert+Q from within the application. Part of the JAWS spoken response should be a revision number. If you do not hear a revision number, the scripts are not correctly loaded. In some cases, restarting JAWS may fix this issue.

Using Compatible Applications With JAWS and the Scripts

This section and its subsections provide tips for using OpenGD77CPS and compatible programming applications with JAWS and these scripts.

Native Application Keyboard Shortcuts

These applications provide several keyboard shortcuts. These work with or without JAWS or these scripts.

• F2 on a treeView node, such as a contact name, will allow you to rename the node.
• Ctrl+F4 closes an open dialog page, such as Basic Information.
• The menu bar's expected shortcuts work, such as Alt+S for the Settings menu.

JAWS Script Commands and Features

The scripts provide the following features:

• When the application opens, and when the last open dialog page is closed such as with Ctrl+F4, focus is automatically moved to the treeView for convenience.
• Space or Enter on a treeView node double-clicks the node. This permits opening dialog pages from the tree.
• The Menu or Applications key on a tree node with a context menu opens the menu. This permits, for example, adding entries to a list such as Contacts. This also applies to Shift+F10, which otherwise opens the System menu in this application as Alt+Space normally does. The Menu key may also work in other situations in this application because of script code, though this will not likely apply to Shift+F10.

Other Resources

At this writing (July, 2026), the community's recognized best source for OpenGD77-compatible programming software for blind users is The Spencer Family Web, www.spencerweb.net. The official home of the original software remains www.opengd77.com.

Russell Breitenstein (KN4MLR) prepared a 42-minute podcast audio tutorial on programming the GD77s using this application with these scripts. The link provided here is to a copy of the file on this author's website, posted because the original May, 2019 Dropbox link is no longer valid. Note that this tutorial advises users to find these scripts under the "Radioddity link" on this website's main page. The link for ham-related scripts on the main page is now called "Scripts and resources for blind ham radio operators", and all ham-related scripts including those for OpenGD77CPS are housed under this area.

Known Issues

Issues shown in this section may be fixed in future script and/or application revisions but are not addressed as of this writing.

Some fields in various dialog pages are unlabeled or mislabeled according to JAWS.

Revision History

This section presents the revision history of these scripts, most recent revision first.

Revision 60, July 15, 2026, tested against OpenGD77 CPS version R2025.03.23.01

• This project is renamed on this site, and within script and documentation files, from "dmr" to "OpenGD77". BX users will need to obtain this update by running the installer rather than using BX Update. For consistency with most other projects, the lower-case name "opengd77" is used in project and website file and folder names. The old "dmr"-based URL will still work so that old external links don't stop functioning. This OpenGD77 script installer will recognize and remove old scripts that used the dmr name.
• The minimum JAWS version is raised from 17.0 to 2019.
• Script code to improve the functionality of the Menu or Application key, and of Shift+F10 for those without this key, is included.
• The APRS combo box in the channel edit dialog speaks its name.
• This documentation is updated to reflect current resources and script applicability.
• Some code for support of very old JAWS versions is removed for efficiency.

Revision 39, October 21, 2023, tested against AccessibleGD77 CPS version 1.1.7

• The "Copy Rx freq to Tx freq" button in the channel dialog is named by JAWS.
• The field naming code is more efficient in general.
• The scripts are compiled against JAWS 17.0, the already-established minimum JAWS version supported, rather than JAWS 13.0.
• The UIA support is refactored significantly and updated to account for recent increases in JAWS' UIA support. A JAWS restart after installing this script update is recommended, though not required. This refactor is being applied to several projects. Users who use several of this author's script sets may notice a slight reduction in JAWS' memory consumption as these updates progress.
• By popular vote, old history entries in this document section are now hidden inside a details tag that may be expanded to show them. Among the benefits of this, heading count is reduced and text searches won't match very old material.

Revision 31, June 10, 2022, tested against AccessibleGD77 CPS version 1.1.7

• These scripts now officially follow the AccessibleGD77CPS code branch but also endeavor to support older software incarnations and, though untested, OpenGD77CPS branches. JAWS should be restarted after this installer runs, so that changes to the JAWS ConfigNames.ini file will be properly detected.
• The minimum supported JAWS version is changed from 12.0 to 17.0.
• The link in the Other Resources section of this document now points to a local copy of Rus's audio tutorial, because the original May, 2019 Dropbox link is no longer valid.
• The messages for these scripts are now distributed in XML rather than jsm files so that translators can create translations with no need for script source recompilation. See the Script Translation Procedure document for details on how to translate these scripts, including how to update the XML message file.
• The installer contains version and product information visible from the Details tab in Windows Explorer, to better identify its contents. This update is being applied to all projects.
• A "directives" text file is included that provides information on how to install this set of scripts manually. See "Handling Directives Files" in the "Common Script Elements" document for further information.

Revision 16, May 29, 2019

• Fixed the installer from trying to recompile the scripts even though they were already compiled and installed.
