Ships & Modules

I am able to fly a Scorpion and have electronic warfare trained to level 4, but I am curious how it works. What other support skills assist with the ECM jammers I am fitting to the Scorpion?

If I am trying to jam a target should I apply more than one jammer to that target or is one enough? I am using the racial ECM's.

Any information is appreciated

As far as skills go:

Signal Dispersion - 5% to ECM jammer strength per level
Long Distance Jamming - 10% to all E-War (including ECM) Optimal range per level
Frequency Modulation - 10% to all E-War (including ECM) Falloff per level

Racial jammers are usually the way to go (they have superior cap usage and range) provided you can put the right Racials on the right ship types. Racial jammers still work against ships of a different race but they are much less potent.

As far as Jam chance goes - AFAIK if you are inside Optimal range it is simply (your ECM Strength) / (Hostile Ship's Sensor Strength) expressed as a percentage. Each module has it's own chance to jam, they do not stack up.
As an example, if you have 2 racial jammers each with a strength of 10, and the hostile ship has a sensor strength of 20, your chance to jam is 50% per module.

You can still succesfully jam outside of your optimal range, but this is where your falloff comes in to play. The further out of Optimal you are, the lower your jam strength. It works as a proportion of falloff. As far as I know it uses the same mechanic as gun falloff (Which you can see here: http://wiki.eveonline.com/wikiEN/images/a/a4/Falloff.png ).

Put one jammmer on them, hold the 2nd. If the first jam is successfull dont use the 2nd untill you need it. If the first one doesnt work, activate the 2nd one. You should never activate more than 1 jammer at any given time. Stagger them so that you always have one about to end its cycle.

Scorpion is to BS what blackbird is to cruiser. It gets standard +15% bonuses to ECM jam strength, and good bonuses to range.

Looking through the previous posts, let me sort them and present the relevant bits.

Warp to 70+. Use your range to your advantage. May want to fit a range scripted sensor booster for longer locking range to fully utilize the long falloff of racial ECM mods.

You WILL get primaried in fleet conflict. As soon as you see a yellow box on your overview, GTFO! Don't bother calling for reps. They won't save you. You don't have enough buffer to survive getting alpha'd out. Once safe, warp back to your logis and call for reps then.

How ECM works: Each module has a jam strength / sensor strength chance to work against the target. If you are operating in falloff, then the falloff chance to miss entirely applies before the jam check.

ECM does not stack. ECM is not stacking penalized.

Racials have greatly enhanced chance to jam the intended racial target, and crap chance to jam anything else.

Against any single target, an on-race racial jammer is always better. At least one of each type is the typical fitting choice. Avoid multispecs for now.

Do stagger your jammers.

Racial sensor type ref:
Amarr: Gold / Radar
Minmatar: Red / Ladar
Gallente: Green / Magnetometric
Caldari: Blue / Gravimetric
Multispec: White

It follows the laws of probability. The chance to jam on any given cycle is the same, but as you get more and more jams, probability states that you have exhausted many of your jam chances, and will soon fail.

It looks something like vague blue with white a drop of green mixed in..... im not sure what color is that exactly... but then again i might be colorblind.

Btw if you are unsure what race a ship is, look at the background of the shipicon. It is right in almost all cases (a handful where it isnt).

Amarr have that golden background, so use the golden jammer... etc :)
