Here's something interesting.I wouldn't argue that consciousness is separate from the brain, but since 2010 we've known that the brain uses it's own EM field (from the firing of it's neurons) to train it's networks and influence future firing - as a feedback loop. Hence you could argue that it is a transceiver - over very short distances.
That said, EM fields interfere with EM fields, so, as we can pick up EM fields using crude sensors mounted on the scalp, the brain is clearly not isolated from external EM fields, logic says it must be affected by them. Indeed there is plenty of evidence to show that it is affected by very weak external E/M fields, and can apparently transduce external E/M fields.

It's clear to me that the idea of the brain working like a radio receiver is underpinned to occur from a metaphysical if not a spiritual plane as is the belief consciousness is non local; existing somewhere other than the physical plane. Ordinary EM fields don't meet criteria
