Spektrum Interference - Help

[dayxwalker]

Hope you guys can help I am having no end of problems with interference for the last month or more. I thought it was down to my Acoms 2.4 set and maybe some of it was. I have since bought a Spektrum DX3S 2.4 Ghz in the hope that it will solve my woe's. As you are probably already guest I still have interference. Below is my full spec and some pictures of my layout

B44
Spektrum DX3S
SR3300T Spektrum Receiver
JR Digital Z9000S Servo
Novak GTB (Not sure if it is Spread Spektrum Optimized)
Intellect Lipo's
Nosram Storm 4 Star

I have a Xcelorin 4.5T combo but it is away getting fixed so I cannot try this to rule out the GTB

Anyone got any ideas on what it can be ? Why did novak introduce a spread spektrum GTB was it for interference issues ?

How can I tell if my GTB is spektrum optimized
