I agree those are two different things.  Like the other poster said, if
you are off on the carrier frequency, it will reduce the range.  I was
having problems with the timing regarding the length of the bits.  I was
using my own modulated bit-banged sender, but using the built-in CCS
rs-232 routines for receive.  That could have also made the problem
worse.

At the time I didn't have a logic analyzer or oscilloscope to be able to
reliably measure how close I was on sampling the bits.  It was pretty
much guesswork.
