I have a XIPAR node that needs a little support with pulseback removal. Never had to utilize this before, but when looking in URD.conf, I don't see the rxdelay= parameter like I do on ACID builds. I went ahead and inserted the command into the file, but there does not seem to be any action. Can someone confirm the parameter and placement? Here is my example: [usb] hdwtype=0 ; 0=std,1=dev eeprom=0 ; unless you have a cable w/eeprom duplex=0 ; 0=simplex, 1=duplex invertptt=0 ;minsigproc=0 ; minimal signal processing ;sendvoter=0 ; 0=default, no voter rssi, 1=enable voter rssi carrierfrom=usbinvert ; no,usb,usbinvert,dsp,vox ctcssfrom=no ; no,usb,dsp rxondelay=3000 ; Gets rid of the pulseback problem ;rxboost=1 ; rx input boost of 20dB rxboost=0 ; no boost rxdemod=flat ; no,speaker,flat txprelim=0 ; 1 = pre-emphasize and limit txmixa=voice ; no,voice,tone,composite txmixb=tone ; no,voice,tone,composite,auxvoice ;txctcssdefault=77.0 ;rxctcssfreqs=77.0; ;txctcssfreqs=77.0; txtoctype=notone; rxsquelchdelay=900 ; delayline in ms carrier squelch tail eliminator rxnoisefiltype=0 ; 0 for +/-5KHz, 2 for +/-2.5KHz systems Lu, KA4EPS
