[App_rpt-users] Question regarding interfacing to a Kenwood Nextedge Repeater NXR-710/810

Mon Dec 30 23:46:23 UTC 2013

I got stumped too
As you know, digital repeaters in digital mode do not support external controller use. however, in analog mode, an external controller such as allstar with a URI/fob or an scom etc, do just fine.  I found it wasn't realistic having the repeater setup to use both controllers on the idea that the internal repeater controller would take over if the allstar computer quit. due to an audio delay in allstar/xipar, somehow there were two paths of audio at the repeater's audio input, so it produced an echo. If you solve this please post it on the site.  Good luck, happy canoe year.......

Ah, good point.. If that is the case, then I am screwed.. I am using DCS and Allstar does not support it, so I have to encode DCS on the repeater side..  I will test it out to see if your theory plays out.
Then I also just thought about the possibility that the data input is for digital mode only. Wonder if that might be the case, anyone know?
Thanks..

I know on Icom IDAS repeaters there is an obscure programming setting regarding disabling internal ctcss encode on external ptt that enables the data input to accept input from dc to daylight… if it is not set correctly the data input is dead.. I am suspecting something similar is hanging you up.. I would look in the help files of the RSS about data input.. Motorola is pretty good about their help files most of the time…  I am not familiar with TRBO repeater programming but maybe similar issues to what I have run into..

Thanks to Don and Ed for the replies.
Here is the latest. Problem ended up being that the URI was not sending TX audio from the locally processed repeater transmissions.  Not sure why, but when I changed the ctcssfrom=no to ctcssfrom=usb   it started to work..  Not sure why as I am not even tying the URI CTCSS to anything.  But regardless I now have the audio.
Ed, I am going to keep the Kenwood repeaters in repeat mode so that if the node should go down, it will at least repeat locally. That was my objective.. So with the External PTT trigger occurring, I have the take over I was looking for anyway. This means that when the node is up (sending PTT) the local repeat audio is not enabled, and that is good so I can take advantage of the Allstar processed audio.
The only remaining item is that I was hoping to send the pre-emphasised audio into the repeater that would be able to handle that audio.  Don mentioned that I should be able to feed it into Pin 8 which is TX Data in, but I am not getting any modulation for some reason.. I will continue to troubleshoot. Worse case, I will go with your plan Ed and go speaker audio..

Haven't hooked up a URI to one but have done some other things.
Your transmit audio should be "microphone" audio, not pre-emphasized. Pin 9.
Rx audio is at 11, squelched. PTT at 16 and TOR can be assigned under function port to whatever pin you like.

In KPG-129D go to channel edit and set operation mode to duplex not repeater. Now the URI should control and handle audio.

Should work on analog or digital. Use simple USB not dsp.

I know this is a shot in the dark and I am probably the only one trying this, but is there by chance anyone that has successfully interfaced a URI to a Kenwood NEXEDGE® Repeater NXR-710/810?
