Is there anyone else having their repeaters stuck open due to node 172/174? I'm getting extremely laggy transmissions, someone keeps connecting everything & my TX is stuck, causing the need to shut down a repeater.

I’ve finally figured it out on both of my repeaters! Sorry about all the confusion, I was burnt lol. After taking a breather & eliminating things one at a time, I interfaced it with 7 wires & no interface board. I think the ICS boards are garbage. PL & crisp audio through wireline. I appreciate you both, gentlemen!

Alright gentlemen, I read into the URIxB's manual. Overlooked the part regarding the 6db gain amplifier. I wired this directly to 12v from the MTR. I soldered a jumper from pin 23 -> 24, changed simpleusb to pick up voice from the Right Output & still nothing. Radioguy, that sheet you saw was the System connecter J5 to the DB9 on the ICS interface board.

Please correct me if I have this mixed up; When interfacing to a controller, does the Radio TX go to the controllers receive audio & Radio RX goes to the controller  TX audio?  Essentially Input goes to Output, Output goes to input?? I tried putting the CTCSS & Cor on PIN 8 of the URI. (Cor_Det) to no avail. 

I will include some more pics to hopefully not confuse y'all more than I already have. When using the "flash" feature in simpleusb menu, it sounds spectacular. I'm to invested at this point to give up haha. What can I say, I like to learn. Thank you both, I hope to stop bugging you soon.

Attempting to get it live on the net lol. I used it as a standalone repeater for months & it was great. I’ll switch it back later today & give it a go. In the 30’s here so I hear you through & through. Moved my soldering station inside as a matter of fact haha. I’m leaning towards your statement, considering no voltage at idle or keyed, & thats coming right off System Connector J5. I’ll keep you posted & I greatly appreciate everything! After attempting to find a “Aux I/O” board, I’m now wondering if there is a way to do the same functions without the board. Build a board, etc?

& yes, I have attempted to adjust the levels in the "Station Alignment" via RSS

Let me add on.. I can key the MTR from a radio, the "receive" light comes on and stays solid until I unkey the radio. The received audio (in BASE station mode) does not get passed the controller, into the transmitter.

Radioguy, I've read every article on repeater builder, I've read the service manual, etc. I am currently using wireline for my TX/RX audio. PL isn't my problem.. Heck, I'd run carrier squelch if I could just get the dang thing to key up from a radio lol. Its gotta be something I'm wiring wrong. First time ever interfacing with an external controller (apart from 2 SM50's I had running with a ID-O-Matic. I have  COR on controller going  to B4 Carrier Detect on the MTR2K. Should I try using the COR & CTCSS on 1 pin together?

My man! Thank you

Already so appreciative of the information! So the controller has output pins for both COR & CTCSS. (https://dmkeng.com/images/URIx Data Sheet.pdf) I unfortunately do not have a Wildcard board, I do however have a wireline, which I'm attempting to use for TX/RX audio. My MTR is set for Carrier & PL/DPL. I have tried using Wireline, Aux audio & wireline, Aux Audio to which none of those options have worked. I've read over the manual along with probably every link I can find relating to this haha.  MTR is set for Base operation, Aux TX Flat, I've tried using no PL tone (CSQ), & have attempted to use 100.0 for both TX & RX. Would I need to throw a resistor or anything to that effect in-line with pin B4, going to the controller? If you'd like me to get screenshots of my RSS or any additional photos/documents, just let me know. Again, thank you so much for taking the time! Side note - I have also tried using "USB" & "USBINVERT" inside the SimpleUsb.conf. I know those settings work due to the MTR staying keyed constantly if I invert the PTT, & returning to normal after switching back.

Gortex, I probed the ground & pin 8 COR with multimeter. I have no voltage on COR when its idle or keyed. Its almost like COR is the issue (its driving me bonkers). The controller keys the radio, sounds great out of the repeater. I just can't get a regular TX to pass through.

I’m using the passive board with the common RC 210/RPi input/output pins. I have C2 high leading to pin 7. A17 TX Audio to pin 22. C17 discriminator to pin 9. B4 carrier detect on pin 8. Those are MTR to URI.

I have a Motorola MTR 2000 repeater. I have an ICS Controller board in the J5 system connector, going to a URIxB via the DB-9 to DB-25, assembled by me. I've done days worth of research to no avail. The repeater & URI both show TX if I key the radio in the simple_usb_tune menu. Hitting the repeater with a HT, RX lights up but no TX on the URI or MTR. Not sure if this is RSS programming or on the URI/Asterisk side. Any suggestions would be greatly appreciated. Thank you all!
