Actually, 200km is very common and many pilots are better. I jam at 212 optimal with no jam strength loss.I accept your challenge!
The optimized Falcon setup for highest stength ECM jamming with perfect skills gives racial ECM mods an optimal of 162 km with falloff of 41km. That means at 200 km range your hit rate is arounf 50% due to being beyond optimal range.
Now, you could use Particle Dispersion Projector rigs, one of which will bring the optimal to 194 km BUT you have to sacrifce not fitting a Particle Dispersion Augmentor rig in place which means you have a signal strength loss to get the extra range.
But wait, I'm not done.
The max targeting range of a perfect skills Falcon is 150km which means that beyond that your jamming strength is effectively zero. Its easy to fit fits or mods to boost targeting range, but once again you need to sacrifice something that increases your jam capabilities in order to fit it.
My point is (and I know I'm belabouring this a bit but I think its important) that you absolutely cannot jam as good at 200+ km as you can at 150-160 km. Sacrifices, as slight as they might be, had to be made to achieve that range. In my experience most Falcon pilots go for maximum jam strength in the min-max calculations but I acknowledge that others in businesses more worried about sentry gun range may opt for longer range.
EDIT: In hindsight this post sounds rather combative toward LurbyJo and for that I apologize.
Its just that there is so much misinformation on what a Falcon can do going around for the past year that I immediately go on the defensive when I see any hint of someone suggesting the Falcon is godlike at 200 km. Sacrifices have to be made to jam from 200km, its not an out of the box ability.
