\n>What you are hearing is an "image" of the real signals, probably up in the
\n>870-890 range or higher. Signals sometimes propagate better at night, hence
\n>why the sporadic "reception". Since almost ALL cell is now digital
\n>(nextel/verizon etc.), few if any are "analog" and even if they are
\n>receivable, can't be "heard" as they just produce a buzzing sound.
