The channel numbers in the RadioIO Plugin are incorrect.  As you can see below, 
the Acoustic channel is using the same port as the 70's channel.

I cannot vouch for the correctness of any of the other channels as I cannot 
find any documentation on the RadioIO web site that defines which ports are 
assigned to which channels.
