1- When to use UniversRadio Transponder?
UniversRadio Transponder (UR IFF) is a virtual MODE1, MODE3 and MODE4 transponder and Identification Friend or Foe.
It is designed for DCS:FC3 NOTA fighter aircraft. So the F-15C…
UR IFF is not needed for A-10C, C-101EB, F-5E3, M2000C, UH-1H and F-14B, in-game cockpit panel settings are taken.
An IFF interrogation works only during a radar locked on, and from FC3 flighters.
/!\ Make sure than the DCS server allows objet export /!\ (see advanced server setting)
With UR Transponder :
- pilots set transponder according to the breifing and/or ATC,
- a human fighter pilot can do an IFF interrogation (interrogation must be done during a radar locked on),
- an ATC software (LotATC) can use IFF or Ident status to manage air circulation.
Launch UniversRadio Control Panel from UniversRadio DashBoard shortcut and choice “Transponder” :
2- How to use it ?
You will find UR Transponder shortcut in the Windows start menu UniversRadio.
Which actions can be done ? And, how to do ?
| Action | Command |
|---|---|
| Setting codes Mode 1 & mode 3 | Left mouse, right mouse or wheel mouse on focused mode |
| Setting IDENT request | Left mouse |
| Setting Standby | Left mouse |
| Setting Mode 4 | Left mouse on "M4" button |
| Doing an interrogation QUERY | Left mouse button Joystick (see UR Control Panel) Keyboard : Query : [Y] |
| Display on top or hide UR Transponder | Left mouse on arrow Keyboard : [Left Alternate]+[T] |
| Get and release UR Transponder as primary Window /!\ DCS will be not able to receive any command when UniversRadio Transponder has focus | Middle mouse button When UniversRadio Transponder has focus, frequency is displayed in orange |
| Moving window | 1. Get the focus : middle mouse button 2. Press and hold left mouse button, move cursor 3. On the good position, release left mouse |
You can customize an IFF code for AI aircrafts. Add #IFF:xxxxcc at the unit name from DCS mission editor. xxxx is the mode3 code and cc is the coalition : UN (unknown), EN (ennemy) or FR (friendly).
Example for a IA A/C name : PARA_82ND #004 #IFF:1204FR So, when an interrogation will be done on this A/C, IFF respons will be -- 1204 FR.
You can change IFF keys by modify ..\Saved Games\UniversRadio\UniversRadio.ini file (read included comments). This key is a secret share of your coalition.

4- Results of “QUERY” interrogation
An IFF interrogation must be done during a radar locked on.
| Result and interpretation | Query window display |
|---|---|
| IFF, transponder, remote squawk is OFF or contact is not locked on | |
| UNKNOWN CONTACT Civilian A/C : An-26B, An-30M, IL-76MD or Yak-40 DCS AI A/C have mode 3 codes begining by 6 with IFF code in UR CP is 000 |  |
| FRIEND CONTACT It is a friend military DCS AI A/C DCS AI A/C have mode 3 codes begining by 4 |  |
| FRIEND CONTACT It is a human A/C with same IFF code in UR CP mode 1 code : 01 mode 3 code : 4548 Mode 4 is on2 |  |
| ENNEMY CONTACT Mode 4 is on2 It is a human A/C with a different IFF code in UR CP or It is a ennemy DCS AI A/C |  |

5- Interaction with UniversRadio ExternalRadio
When both, UniversRadio ExternalRadio and UniversRadio Transponder are launched, UniversRadio Transponder is displayed below ExternalRadio window.
UniversRadio Transponder window can be moved.
When UniversRadio ExternalRadio has focus, both windows display frequency and code in orange color.
