I get the feeling that a 1 second delay between digits might be a
little too much.  The other sky.sh script has 0.1 seconds, which
sounds much more reasonable.  If you are too slow sending digits to
the Sky decoder, it times out and changes to the channel given by the
digits it has already received.  Since Perl does not seem to have the
ability to sleep for fractions of a second (at least with any builtin
Perl function I have found so far), I think I may change over to using
a modified version of the sky.sh script in order to do short delays.

Yes, I could have set up the freqid values that way.  I just found it
easier to remove the front 1000 digit in the channel change script,
rather than go back over my SQL and change all the freqid values.
