MiG-21 Jammer Works!

[viperdogsnake]

Been testing against SU-27. Forward Head on, its not very effective. On a chase down scenario, it held my lock off until 14 km. This was in pulse mode.

[Random]

Will test this later!

It has various effects against different radars. Been real interesting to test. Seems like it jams the best to your sides and rear.

I was messing around with the jammer pod this morning on the open conflict server this morning to see what it would do. I climbed up to roughly 25000ft, turned on the music, and proceeded to fly straight and level into bandit country to see how long it would take me to get shot down. I was very surprised at how far I got. Wound up taking a heater from an AI CAP to bring me down.

 

I also tried orbiting above some of the other players in their fighters to see if it would have any effect, but no one was very talkative when it came to replies to my inquiries. Nonetheless, this could be very interesting if it is permitted for use in the next round of Blue Flag.

xxJohnxx needs to make a video about this.

 

We should do extremely detailed testing on an empty server with a partner, flying around and seeing what happens if the jammer is set to different modes.

 

According to the manual the left most switch is the power switch. Up is on.

 

The next switch from the left says "ACTIVE" (up) and "PASSIVE" (down) the manual refers to it as "Reception (Down)" and "Emission (up)" Maybe the power switch simply powers up the container and the "Active/Passive" switch turns the actual jammer off and on?

 

The third switch says "PROGR". In the Russian cockpit there's a 1 and 2 but they are missing in the English cockpit. According to the manual up is 1 and down is 2, and they're referred to as "Jamming Patterns." (Which is odd considering what comes next.)

 

The fourth switch says "Cont" (up) and "Impulse" (down)

 

Manual says they're also jamming patterns (Continuous and Impulse).

 

Why do we have two switches for jamming patterns? We have 1 and 2, and then Impulse and Continuous.

 

Like I said, we should do testing together. Fly around with switches on various positions and see how various radar equipment reacts. I'm assuming the MiG-21 will be effected the most by the different patterns if they put the effort to model them in. (assuming they actually make a difference)

 

I'm most curious how the filters on the MiG-21 deal with the different patterns. Normally with the "generic" ecm you turn on Continuous or Intermittent filtering and the jamming lines go away like magic, but maybe it'll be more detailed against the SPS-141.

 

Give me a PM if you're interested in testing on an empty server together.

For all i know "Active" means that the jammer is emmiting noise to radars and "passive" should be chaff dispense for defence against fired upon or to loose lock.

My only guess is that one of them is defense against Air threats and the other is SAM. This thought is coming from the A-10C jammers which has 4 mods (Air,AAA,SAM1,SAM2).

 

I did a lot of tests both against AI with AIM7 and Hawk system and also with my buddy. AI Aim7 looked like i could survive 4 simultaneously launches just by flying straight and small altitude changes (ofc it could be random luck, but on the tac view seemed like the lost track easy). I cannot tell how the Hawk systems rly work. But they could launch at me from 30km distance with no rly effect, at 15km i was dead with no hard maneuvers. I did not see those work when i was in the f-15 against my buddy in the mig. 95% AIm7 would track and kill form ranges < 10miles.

However flying in 104th server last night( OP.BIson no Aim120). Did not ate a singe missile while i got chased a lot.

I use Active,progrm 1, impulse. then manual dispense and single (Since auto dispense doesn't work). And i see my jammer online and the signal red light blinking (ofc these doesn't mean anything is working).

Overall i am not a tech and i am not aware of the proper numbers the manual is extreme laconic and LN did not gave us a single line of changelog so everything is random in my opinion.

 

EDIT: The SPS-141 pod was made to defend air crafts from HAWK batteries and Sparrow AIM7 missiles. DO NOT think that it can do anything against ARM R-27R-ER, Aim120, SUper350 e.t.c. It does not work as other jammers ( radars see u normal , no strobes are emminting from it) .

It does emmitt strobes,we tested it out for four hours last night. In impulse if a su27 is chasing u down it wont allow you to take stt until 14km. In the fwd qtr its not as effective. We were getting burnthru pretty easy and employing. If you really want to see effects you dont fly the-21. Your buddy does and you fly something else and try to kill him.

What position to you use. I was in an F-15 we tested numerus compinations and i never saw nothing. long or short range..

Try multiple aircraft if you have the modules, with a human flying in jammer equipped MiG on other team. You will get jam indications. The 15 it seems does the best job dealing with it, but in a flanker manuevering it prevented me from getting an stt. Tws was able to maintain for some reason. Have your buddy try different modes of jammer while you see the results.

[BadHabit]

Gave it a try vs AI Mig. The f15 will burn the jammer at 35-40 miles and the 27 at 40 km with stt lock about 20km. Will try vs Hunan when available.

[BadHabit]

I confirm the same numbers vs human also. But vs su 27 while I see strobes as close as 10km I can get dist and stt lock.
