 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 7laptop. 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. Bothyield 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
