Years and years ago,my old buddy's son installed an AM/FM stereo radio
in his car.It wasen't but a few months later the radio started cutting
in and out.One of the speaker wires on one of the stereo channels had
come loose.I once bought a sound amplifier (it looks sort of like a tiny
transistor radio) from a Radio Shack store,the gadget requires either
earbuds or earphones,it doesn't have a built in speaker.I left it turned
on one day and the earbuds too close to each other,the gadget started
cutting in and out (I took it back to Radio Shack and got another one)
just like that stereo radio did.That is how I know it isn't a good idea
to leave a radio turned on and let the earbuds get too close to each
other.Ever since then,if I am using earbuds,I take pains to make sure
they dont get too close to each other.
