[App_rpt-users] Ptt activates on and off

Im just about done setting up a friends Node but we run into the ptt acitvating on and off. I can see that in the CLI. It receives DTMF fine but PTT gets engaged off and on. Ive toyed around with usb.conf to no avail. Node is set to simplex and any information is appreciated -- Gracias y 73's Hasta la Vista KI6LNX
