Well, when an APCO-25 signal starts to faid it sounds more robotic, and
then it faids out.  I wish I had had my digital scanner on when I heard
the modulation.  Does anyone know how well the software for this system
works with JFW?  I have heard not too good of things about Motorola
equipment, but what about the other vendors like Uniden and E.F. Johnson
and the other P-25 radio manufacturers?
