POCSAG/FMRDS interfering with mplayer and Pi crashes 3B+

[r1bnc]

I installed this on my Pi 3B+, I tested the POCSAG and FMRDS programs. After that, I played a music stream on mplayer but it says:

MPlayer 1.3.0 (Debian), built with gcc-6.2.1 (C) 2000-2016 MPlayer Team

Until I reboot the Pi and do not use pocsag/fmrds, mplayer works. WiFi failure was caused by UFW blocking my ports and I get disconnected from SSH due to a corrupt file.

The other urgent problem is that the Pi reboots by itself while transmission/after transmission randonmly. Tests are ongoing. I am using RPI 3B+, WiFi SSH access only. Installed the Master branch.
