16/1030 - DCS Simple Radio Standalone Install

### Update Instructions ###

1) Make sure DCS Simple Radio Standalone (SRS) is NOT running at the time of update.

2) Run the .NET 4.62 Web Installer…  Located in “Dropbox\BlackKnights\Voice Comms”.  The installer supports all versions of Windows, and will automatically install the correct version.  You should still run this even if you already have .NET 4.62 installed.

3) From the same Dropbox location, locate the subfolder with the latest version of SRS and INSTALL by running the “Installer.exe”. 

4) Confirm the install locations are correct then Click “Install / Update DCS-SRS”,  and acknowledge the “Success” pop-up

5) Launch the “SR-ClientRadio”,  and set your Microphone Boost to -90% (minus 90) and Speaker Boost to 126%.  Use the cursor keys on your keyboard for more precise control of the sliders in tens. Select your correct Microphone and Speakers hardware from the drop downs.

6) Test using “Preview Audio” and adjust as required.

7) Add the “Black Knights” SRS server to your favorites.

8) Confirm your controls are mapped properly

9) Under “Settings” tab, confirm the following settings match the screenshot below


New for this release is an optional SRS In-Game OVERLAY using the native DCS GUI. This benefits VR users and those who run DCS in full screen mode, as you can now see the currently set radio frequencies and your active radio from within the sim.

The In-Game Overlay has 3 states, Hidden, Small & Full that you can toggle by pressing “Left Control + Left Shift + Esc”.

The Full state has a title bar that you can click and drag the window around with. The window position will be saved for when DCS is next opened.

Exciting, huh? There’s a huge “HOWEVER” though…


Pressing “L Ctrl + L” while the In-Game OVERLAY is displayed will result in SEVERE FPS LAG. Pressing “L Ctrl + L Shift + L” resolves the lag problem.

As this key combination IS mapped in some DCS modules, pilots choosing to use the new In-Game OVERLAY must be aware of this major bug and how to resolve it. Steps should be taken by pilots to prevent generating the “L Ctrl + L” key presses in their profiles.

As this bug ONLY appears when the In-Game OVERLAY is ACTIVE, pilots that choose NOT to use the In-Game OVERLAY should experience no issues. You may continue to use the default SRS Overlay in a separate window.

Pilots that want to take the extra step and REMOVE the In-Game OVERLAY from SRS entirely, can just delete the following files:
