OP25 OP25 has suddenly stopped running

[robocock8191]

Hi everyone,

I have recently just gotten my RTL-SDR and have setup OP25 on a Ubuntu virtual machine on my macbook.
Was running quite well. Today I was getting many encrypted transmissions on TG's I hadn't blacklisted yet.

So I would quit op25, add the TG to my blacklist in the Trunk.tsv file, then restart OP25.
I feel like the last time I maybe quit too fast, as if it were barely finished loading up. And since then OP25 will no longer run. I have tried replugging my SDR, rebooting the system but no joy unfortunately

It starts to load then just spits me back out at the terminal prompt. No error given.


Here is the contents of my stderr.2 file

Any help would be greatly appreciated. I don't really wanna trash the virtual machine and start again.

I think it says you messed up your blacklist.

Double check it.

Then triple check it.

Also - what is the contents of your op25.sh file?

Thanks for the hint. I couldn't figure out what it was, but clearing the blacklist would fix the problem. Anyways, i found the problem to the comma at the end. After deleting it I am up and running again

maus92 Here's my op25.sh file

#! /bin/sh
cd ~/op25/op25/gr-op25_repeater/apps/
./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -f 417.4625e6 -o 25000 -q -2 -T trunk.tsv -V -2 -U 2> stderr.2

Thx. Glad you found the errant comma. Note that your -S value need not be so high, and that you don't need the -f parameter if you define the control channel in your trunk.tsv file.
