This is doing my head in, this morning of course, all is sweetness
again, and no amount of fiddling about can produce the fault.

I suppose there is one option which could cause this problem, and that
is pick up of some rf or noise from the mains or via the long wire
fromm the psu brick, and when said noise is not present, the thing
behaves itself.

This might point to poor filtering in the part of the psu inside the
radio. More testing needed, but its a real pain.

Its no good returning it under the repair warranty if when it gets there
its perfectly ok.

You can get clip on ferrite beads to reduce RF on a lead.
