Thanks Iain and William for the reply....and I don't mean to change directions either, but I'm needing to find out the installation instructions for wireshark now...the directions from the op25 got me to where that one worked for now...I then went on to the wireshark section and was stopped at the svn portion...seems the patch and plugin code aren't at the location in the instructions....also, what version is working for this? Sorry for the abrupt change all but have to keep focused....

Is very likely there is an error in either your trunk.tsv file or in your rx.py command line.   An error in either or both will cause the abort.   If you’ll download and install TeamViewer then I can help you fix whatever is broken over the internet.    TeamViewer is free for personal use.

Once installed then send me a PM and we can setup a schedule to talk over the phone to work on your installation.

I am running the boatbod op25 and as soon as it starts to output voice traffic it aborts. I'm runnint Ubuntu in virtualbox in a Windows 7

laptop. This is a new install of Ubuntu 16.04 and have both op25's loaded but only the boatmod op25 installed. Below is the script to run rx.py. Below that is the stderr.2 output. I've used both the install.sh script as well as the manual load from the install.txt file. Both

yield the same results. 




cd ~/gnuradio/bod/op25/op25/gr-op25_repeater/apps

python rx.py --args 'rtl' --gains 'lna:49' -f 852.6738e6 -q -1  -S 1000000 -P constellation -o 50000 -w -2 -U 2> ~/stderr.2
