Radio Modulation desync/reversion

[UncleReiben]

Greetings,

Testing DTC functionality and I've noticed the radio modulation in the Hornet doesn't display the change when switching between AM/FM. Upon loading from a DTC, switching channels from 1 then back to 1 changes Amplitude to Frequency Modulation.

Pressing the PB does functionally change the modulation type but the UFC doesn't display the change until you pull the channel selector knob (assuming it syncs on state change?) However, if you change channels and then return to channel 1, the modulation reverts to FM every time (visually and functionally.)

Verified that the DTC interface does have that channel set to AM, DTC file assigned to Hornet in Mission Editor but not set to auto load.

Unsure if this is a Hornet issue or DTC issue or both. Haven't had chance to load into a mission file that has no DTC file associated. Please move thread if needed.

Tested with:
DCS 2.9.15.9408
Afghanistan
Through The Inferno (Afghanistan - Bagram-Kabul) v2.6.1p
Single Player
Cold Start

I noticed this too. It changes on srs layout but still displayed as fm on ufc. Also, dtc guard channel enable option doesn't work.

I noticed two things:

The DTC COMMS Menu is bugged and doesn't save or display the modulation correctly. If I save as AM it is FM in the game. I manually edited the .dtc file, replacing

"modulation": 1,

with

"modulation": 0,

and it is then correct when loaded from the DTC.

The second thing: if I want to change from AM to FM and vice versa, I have to press the FM/AM button, then press ENT on the UFC, then change back and forth to see the change.

...and when entering a frequency (in the DTC manager window) it changes from AM to FM without user input.
