Try tuning to a spot on an FM radio where there's no station. Then grab
your 85 (I know the 85 does it, dunno bout the 92) and hold it close
(~4ft) to the antenna. You can hear the processor idling, and
calculating, and doing screen updates. I kinda wondered about cancer
m'self.... I wonder how much EMF it's kickin out. I'll have to check that
out tomorrow.. Anyway, you can hear an 85... try a 92. Could this be our
elusive radio link? :) [doubt it]
