nothing like a DCS vid and eating cornflakes in the morning : )
How'd that day go 1 year ago
Coffee here :D
You could take the aircraft you're aiming at and make it invulnerable then take radar guided missiles and do some experiments locking it up and firing the radar guided missiles at it. Jammer on/off, countermeasures firing and not firing. Go through all the combinations and see what the results are. You could also try Sparrows and AMRAAMs as I would think the jammer is designed to jam the Sparrow and possibly the the AMRAAM being a later/better missile would be less effected?
Might be an opportunity for you to get some Hornet practice Cap while performing the experiment/s?
Wouldn't jammers be tuned to the likely frequencies of enemy NATO aircraft? Might wanna test it vs NATO aircraft and have them set as enemy in game.
Doubt. Actually jammers receive the radio wave which is locking you. Then it amplifies it and starts to broadcast on the same frequency, but with fuzzy density. Modern ecm pods can broadcast up to 14 frequencies at once, I believe. Maybe they are too close that is why it did not worked, or it is not modeled correctly in the game.
@@velizarzdravkov6686 cool! I learned something today

I had an SU-25T jammer work very well on me, so I think you have to fly towards the target to jam.
What a dissapointment. I was using that pod many times in multiplayer believing that it gives me some level of protection. Now seeing that it is just a useless ballast on the aircraft. Saaaaaad.
lol
In Chucks guide he mentions the ecm isn’t working. But that was version 1.2. Something. Maybe it’s still a lingering bug.
Ran some tests with it, it's a hit or miss with the jammer.
Definetly not working with modern aircrafts though
agree
Maybe the jammer doesn't have 360 degrees transmission capability. Try locking head on.
Yeah, especially considering only the tip of the pod is painted “antenna green”...
Jammers are very directional and are most powerful if they are pointed down the main lobe of the target radar (head on). Jamming through side-lobes is many tens of dB less efficient and jamming through back-lobes is not very efficient either. I don't know the front-to-back ratio of the MiG-21bis radar, but as Hawk 6.2.0.1 said, try jamming from a head on aspect.

Good point. 2nd clue might be the fact that guys are close to each other. 15 km isn't that far. Maybe the radar has beaten through the jamming signal. Have you tried on a greater range? The active jammer should be visible as vertical bar with spikes on sides (impossible to lock). Jammer prevents measuring the distance.
Oh one more. I guess there's some mistake made while describing the top panel. For me the "SIGNAL" red lamp turns and stays on when the bottom switch is in
up position "CONT" and the lamp blinks if the switch is in "IMPULSE". It has rather nothing to do with being locked or not it just tells if the jammer actually emits anything or not. Correct me, if I'm wrong...
maybe his pod is only here to counter HAWK and other old SAM.
Yes, a valid idea. The HAWK is a stated target platform. The SPS-141 operates within the frequency band of 8.82 - 10.71 GHz. This means the X-band, which is also much used by fighters and interceptors. I have been searching for info regarding the frequency span of the RP-22 (SMA), but detailed info is scarce. Still I would think that it is likely somewhere within the operating frequencies of the SPS-141.

Ok Maxwell
anyone bother to report it is still inop to the devs?
Idk. Did you
Thanks

Nice got first view
Unintelligeble english for foreign lol
Crap module plain and simple.
To be honest there is no reason to use the jammer on the 21 in dcs anyway. Any modern aircraft radar would most likely see through the jam, and any aircraft of the same era has such crap radar most people don't even use them.
I have the module, and I would say that it's well worth it, even if things are a little buggy. It's flight model and asset quality is fantastic!
I beg to differ.
And whether jammer is bugged or not overall a great model. I have F-5, M2000 as well as Hornet and the 21 Bis gets a workout about as much as any one of them.
agree, what you get from the MIG is proportional to the time you put into it - it's a great module
Lol what
Thanks
