[App_rpt-users] How to configure non DSP on a URI

I am trying to help someone attach a node to a CAT controller and this is
the first time EVER that I am not using DSP.
Seems like we are having issues with COR and also RX audio. Since I have
never used these inputs, we need some help.
Here is a sample entry in the URD file and was hoping that someone might be
able to supply a few tips.
I am not using CTCSS so I said "no" and am using a logic high when no RX
signal present, the CAT controller drags down to 0 volts upon signal
detection on the repeater receiver.
I am not getting any action when this happens though. I even tried to use
"USBINVERT" but that had no effect.
I see about 3 volts when idle.
Any thoughts?

Note I even tried to use VOX and that did not work for some reason.


hdwtype=0           ; 0=std,1=dev
eeprom=0            ; unless you have a cable w/eeprom
duplex=1            ; 0=simplex, 1=duplex
invertptt=0
;minsigproc=0		; minimal signal processing
;sendvoter=0        ; 0=default, no voter rssi, 1=enable voter rssi

carrierfrom=usb      ; no,usb,usbinvert,dsp,vox
ctcssfrom=no        ; no,usb,dsp

rxboost=0           ; rx input boost of 20dB
rxdemod=speaker        ; no,speaker,flat
txprelim=0          ; 1 = pre-emphasize and limit


Thanks!
