As I understand it, this is audio streaming via the internet so it wont 
have the bandwidth restrictions of a SSB Tx/Rx so there will be no 
problems sending 2975 Hz or higher frequencies.
Please correct me if I've got it wrong.

Also please can someone explain the rationale behind downshift on mark 
or downshift on space or is it just a convention.
