[2.9.17.12034] Air-to-Air TACAN not working in MP between two human-controlled F-4Es

[Stickler]

I originally noticed this yesterday during an MP cold-start mission but was able to recreate the issue today in my private LAN with air spawns.

Currently, the Air-to-Air TACAN functionality seems to have been lost (it worked in previous versions) between two human-controlled F-4Es.

Note the attached tracks, one from the each aircraft involved (the first aircraft acted as the server).

With 15Y and 78Y set in the aircraft respectively, I would expect a DME readout to be available.

Regardless of T/R or A/A T/R selection with 2x TACAN selected on the navigation control panel, no DME is obtained in either aircraft.

I have tried various other channels and the X band with the same result (partially shown in the tracks).

This is possibly related to this issue.

This report confirms my observations with the use of A2A TACAN function, which wasn't working in MP in the Phantom during one of my latest flights.
My aircraft was F-4 with me as pilot and another player as WSO. Other aircraft was a F-14, human controlled pilot and Jester as RIO. We weren't able to get it work, even after 10 minutes of struggling around with that, and finally being shot down because 3 heads were totally stuck in the cockpit finally finding out it didn't work ...
