Are you using shielded conductors for feeding audio to the
powered speakers? If so, is that shield connected to the sound board's
ground and in turn to an earth ground? Are you using balanced input and
output to feed the powered speaker (TRS or XLR) or is it only a 1/4"
mono (unbalanced) connectors?|

When you unplug “most” of the snake does it go away? I assume you need one line to feed the monitor.
When the station comes through, is it with inputs on the console turned up?
How good is the grounding of the console and/or the speaker? Look out for ground loops. The ground in the power plugs may not be good.
