Does anyone know about the Comdel CSP 11 speech processor?  I am trying 
to troubleshoot a recalcitrant one.  What is the carrier frequency? I am 
measuring 17.4 KHz and don't know if that is right or wrong.  The manual 
isn't much help.  Other how to hook it up and a schematic, there isn't 
much in it.

I keep thinking that years ago I read something about the Comdel saying 
it used 85 KHZ as the carrier.  So far Google searches haven't turned up
