DCS-BIOS unable to adjust ground radar display knobs

[hurricanenz]

DCS-BIOS version
0.8.0 [2.9.3]

DCS-BIOS Control
DcsBios::PotentiometerEWMA<5, 256, 5> radarAngle("RADAR_ANGLE", A3);

DcsBios::Switch2Pos radarAoacomp("RADAR_AOACOMP", 10);

DcsBios::AnalogMultiPos radarMode("RADAR_MODE", A2, 5);

DcsBios::PotentiometerEWMA<5, 256, 5> radarVol("RADAR_VOL", A1);

Describe the bug
When changing an input for the Radar panel to all of the above control references, the game will change visually, dial will rotate and switch will change position, in-game sound of change will happen but will not actually change input state.

To Reproduce
set position of mode switch to A/G{last position) while on ground power on. Dial will move to A/G but radar display will not change. I then can click once right mouse button and the radar will start.

This is true for the radar angle , radar AOAcomp, radar mode and radar volume.

I can set the values through BORT by increasing Radar Mode/input/fixed_step/ INC. I change from off position use the INC button and the Output value will change to 4 and 100%, in cockpit it will show the position of the dial at A/G but the radar screen will be in a off state.

Expected behavior
The input change to match in cockpit operations

Additional context
I am using Arduino Nano with other outputs configured and functional. I have tested on a new Nano using only the code relevant to the radar.
I have a Armament panel that works purely off DCS bios and have no issues with similar code.

Software Information (please complete the following information):

• DCS Version: [DCS 2.9.3 Open Beta latest]
• A-4E Version latest release.

I have posted this in bugs on DcsBios github see linked with their comments and troubleshooting methods.

Any chance this is related to these lines?

I don't work in C++ so I wasn't sure how to compile and test myself, but it seems like the other commands (which have keyboard keybind support) call ed_cockpit_dispatch_action_to_device, but radar_mode doesn't

@callmepartario could the above be the source of the issue?
