Hello Steve,

That sounds a good idea for the audio, I'll make use of that in my " Mk2 
" model.
I was curious how simpleusb stopped working for me, hence the reason for 
trying usbradio with the BF-888.
Now I'm installing a fresh image and starting with the default settings. 
While I sort this out I have two nodes running usbradio on my netbook 
and when I connect another node locally that's configured with simpleusb 
I get distorted audio via the simpleusb node but if I connect the 
netbook nodes and the simplusb node to an external node the audio is 
fine.
When I had the simplusb working I noticed that the rxed audio appeared " 
louder " that the usbradio configured nodes, configuration again I 
guess.

Regards,

Ian..
