Trunk-Recorder instance with two nodes?

[zlandmedia]

I'm looking to move from SDRTrunk to Trunk-Recorder with my two Calls nodes and with Trunk-Recorder I've run into an issue where it will not run both nodes. This is happening when I use both a Raspberry Pi with Pi OS Lite and WSL inside Windows 10.

When I use the below config.json, I get this error:

Am I doing anything wrong with my setup here, or is it just not possible to use trunk-recorder with two nodes on one instance?

Thanks,

Zach

If you don't get any answers here, try the Sdrtrunk Google group here, sdrtrunk - Google Groups

Trunk recorder had this chat group but they may have moved to to a Discord here

This is your problem. You need to adjust your RTL center frequencies to properly cover this channel. It's not being covered in the spread between the 3 sticks.

I got the center frequencies in my config file from this site, which was linked in the trunk-recorder github.

I copy-pasted the frequencies from the east and west sites of this system, and this is what it came up with:


Are those the wrong center frequencies?

I copy-pasted the frequencies from the east and west sites of this system, and this is what it came up with:

The directions there say,

Find your site on the Radio Reference DB and copy/paste all of the voice AND control channels here directly

You are combining two sites. I am not sure if that will work or not. Been a long time since I played with that program.

Just wanted to circle around and mention that I got my setup working!

Thanks to AlertPageSDR, I found this repository, which generated a configuration for me based on the system and sites: GitHub - AlertPageSDR/tr_configurator: Tunk-Recorder config auto generation with Radio Reference

Then I read through the trunk-recorder errors and saw that my USB memory size needed to be adjusted, and the solution was here:
