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

[Johnny Keeker]

Looks like your using zippppper if so, this works on my cat 200.  The audio is set up as in the instructions.
I just like using a signal generator but I find without a hardware controller xipar tx audio is a little low
even with txboost=1

hdwtype=0 ; 0=std,1=dev
eeprom=0 ; unless you have a cable w/eeprom
duplex=0 ; 0=simplex, 1=duplex

;sendvoter=0 ; 0=default, no voter rssi, 1=enable voter rssi

ctcssfrom=no ; no,usb,dsp
rxboost=0 ; rx input boost of 20dB
txboost=1

txtoctype=notone; 
rxsquelchdelay=80 ; delayline in ms carrier squelch tail eliminator
rxnoisefiltype=0 ; 0 for +/-5KHz, 2 for +/-2.5KHz systems
;rxfreq=446100000 ; for rf module equipped nodes
;txfreq=446100000
; Receiver Audio Low Pass Filter Options
rxlpf=0; 3.0 kHz cutoff. Default value for reduced noise and increased intelligibility.
;rxlpf=1; 3.3 kHz cutoff for increased high end, sibilance and brightness.
;rxlpf=2; 3.5 kHz cutoff for even more high end, sibilance and brightness.
; Receiver Audio High Pass Filter Options
;rxhpf=0; 300 Hz cutoff. Default value to reduce sub-audible signals for retransmission and in the receiver speaker.
;rxhpf=1; 250 Hz cutoff for additional received and retransmitted bass response. 
; We recommend using this filter with a CTCSS tone no higher than 186.2 Hz.
; Transmitter Audio Low Pass Filter Options
;txlpf=0; 3.0 kHz cutoff. Default value.
txlpf=1; 3.3 kHz cutoff for increased high end, sibilance and brightness.
; Transmitter Audio High Pass Filter Options
;txhpf=0; 300 Hz cutoff. Default value to reduce interference between voice and sub-audible signaling tones and codes.
;txhpf=1; 250 Hz cutoff for increased bass response in transmitted audio.
txhpf=2; 120 Hz cutoff for special applications requiring additional bass response in transmitted audio. Not recommended due to the increased possibility of voice energy interfering with sub-audible signaling

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.
