If the pod is anything like the DECM I worked on in the Navy it's not a jammer.
The EA-6B Prowler and now the EF-18G Growler are the active jammers (ECM) in the USN. They will pick up, identify, classify and activily jam a signal, whether it be Command and Control, Search RADAR, Fire Control RADAR and continue to Jam it. I was in from 77 to 97 and worked on AN/ALQ-126 and 126B Deception Repeaters............. they are tuned to come on at a certain range to the "FIRE CONTROL RADAR" and tuned to turn off (stop responding). Deception Repeaters have a Threat Library of know Fire Control Radars and will respond to them Pulse for Pulse as long as it's in the range envelop of its effectiveness and the lethal range of the threat missile. It's used only to get you into and out of the target area. The threat RADAR guidance pulse is received drowned in noise and then a false return pulse is sent that will give false range or azimuth information. This will confuse the guidance system to break lock on or hopefully break lock on.
Deception repeaters will not respond to search RADAR, your RHAW, RADAR Homing and Warning reciever will tell you there is a Search RADAR out there, along with all the Fire Control RADARs. That's where that Threat Library comes in handy. The Deception repeaters will respond to Air and Ground Threat RADARS. DCS World does not simulate a aircraft with a ALE-41 style Chaff dispenser that will lay down a corridor of chaff, much like they did in WWII to cloud the sky with aluminum strips cut to different lengths to confuse the different wavelengths of Search and Fire Control RADARS. Of course now a days we depend a lot on a Aircraft's Stealth. The JSF F-35's RADAR is linked to it's ECM suite and is supposed to be able to inject a virus into fire control RADARS, Command and Control Systems. We'll see if they get the software worked out in it to make that possible.
So the answer to the DECM pod on the A-10 is "DO NOT LINGER IN THE TARGET AREA"........... One Pass Haul Ass......................
