Hello all,
I want to set up an app_rpt server with two independently functioning simpleusb nodes: 
Node 1. Full duplex repeater 
Node 2. Aux transmitter

The second node is nothing more than a transmitter (TX audio, PTT) so couldn't I simply configure the second node's simpleusb.conf file with "gpio4 = ptt" ,  "txmixa=no", and "txmixb=voice" ? 
Thanks and 73


I'm 99% sure you need a USB interface per echo radio connected. 

If you just want to send a signal out, then you could setup a dual band radio that'll do cross-band (ass/u/me'ing the 2 nodes are on different bands) and shoot out the RF that way.
