Not near my books but thought popped into my mind. If a Technomancer threaded resonance channel to a drone and then used mind over machine echo. Would they be able to maintain the resonance channel of it is sustained? I also forgot dose the complexe form just remove distance or also background static? Would this bypass jamming?

Resonance Channel simply reduces Noise due to distance. This is a sustained power, so yes a technomancer can sustain it while jumped into a drone, and it will mitigate any Noise penalties due to distance. It does nothing against static or jamming.
