Yes, that's what I meant: noise we generate in the CPU can sneaking
out and, say, hitting GPS. Given the current poor RF design, this is
probably already happening, it's just not bad enough that it would
lead to something clearly visible as a failure.

We could actually test this: rework a device such that only GPS is
powered and communicate with GPS from a remote system (over a
properly exorcised cable). Then compare the performance between this
system and a regular device.

Ah, so many ideas, so little time ... and so few devices to
slaughter ;-)
