So, i have the issue tzhat my radar will NOT even try to search or lock, i am literally spamming the button and with a chance of 1/100 that green square pops up trying to find something, the enemy plane can be in my direct visual line, right in front of me and it will not work.
What aircraft are you even exactly having an issue with its radar? You have different types of radars in-game with different modes so you need to be more specific, because all I can assume is that maybe you are using an aircraft with a radar rangefinder but even then, that is a very loose assumption.
do you have a clip of this?
I wonder if you are in the wrong IFF mode.
As MiGoon said, need a clip to see better what is going on
