My cellphone is usually near my PC speakers on my desk. It always 'squawks'
about once an hour and squawks again a couple of seconds before a call comes
in. You can hear cellphones doing this if you put them near any audio device
with an amp. The most active phone I have seen belonged to a colleague of
mine. He used put it just in front of his PC monitor. When it squawked or had
an incoming call, The monitor screen used to Pattern like it was being
degaussed. Oddly enough he sold it within 2 weeks of buying it. If it did
that to his monitor, What was it doing to the old grey wetware !
So who needs an LED? the damn things have such an effect on everyday
equipment, that you know exactly when they are sending something. :o)
I even went so far as to put an old cellphone in a microwave oven,
along with a pocket radio. Obviously the oven wasn't on, but I was VERY
tempted:o) I turned the phone on inside the oven and quickly shut the door.
It squawked constantly every couple of minutes while it tried in vein to get
a signal.
