[App_rpt-users] 2 nodes using DIAL on a RPI2

[Skyler F]

Whats the max number of USB nodes the pi processor can handle on

A. DSP (usbradio)
B. COR + De-emphasis audio (simpleusb or usbradio)

I have a pi that I would like to set up in the vehicle and run 1 UHF
simplex remote base, 1 VHF simplex remote base, and 1 900MHZ full duplex
repeater but I might need 2 pi's or something.
