Michael:

Just to make sure its out there ... the DSP software doesn't decode some 
standard PL tones.  It will generate anything to the TX.  If you haven't 
run this down yet ... I remember seeing a list of PL tones but I can't 
find it now.  I use the method you are trying to use and it works 
without any problems.
