SPS-141 on Su-25, is it working at all?

[Schmidtfire]

I tried the Su-25A SPS-141 jammer pod yesterday, and I am trying to find out if it actually works. I push "E" on the keyboard and ECM light in the cockpit flashes a couple of times and then goes solid. Tested against AiM-7M Sparrow (F-4E, F-15C) and SAM Hawk, but didn't seem to make a difference at all...

Like other jammers in DCS it only helps at long range. Aim-7s will be too close to be significantly affected by the jammer.
