This is my remote listening post. I have it patched into a personal audio feed for friends and family. In addition I can listen to it through the amplified speakers, or through a bluetooth audio stream, both of which are real time. I can also monitor and remotely control the scanner through a separate feed that I have set up for myself only. This allows me to only need one scanner for both home and away and my smartphone is much more convenient to carry around. I also run recording software so that if I miss something I can go back and listen to it.
