No idea.  You could try it and see if it helps.  ;-)

(Actually if you chose channel 6, you'd still be getting interference
from 11, and vice versa.  So it may not help, either.)

I don't know how wireless phones work (at the physical layer, that is),
but I think this may be possible.

I'd agree with the "try taking it somewhere remote and seeing if you get
any other results" idea that was also posted in this thread.  This does
sound suspicious to me, and taking the whole setup somewhere else would
show you whether the problem was the other signals or the hardware.
