Thank you all for the conversation, it is pretty interesting.  That makes sense 
that they have a proprietary protocol, it's a shame though.  Is the text that 
comes through encoded in a proprietary way?

Does anyone know what the frequency of channel 1 is on (I'd like to see if I 
can even see the signal popping up above the noise)?
