I would like to setup a private connection over wi-fi to actually control the scanner and listen to what is being heard. the display would mirror the scanner display. There would only one person on the connection. No internet would be involved.
I think that I understand what you are attempting... since you mention the pi i can tell you how i do it. Very simple. Setup darkice on the pi to do the audio streaming. On the same pi, set up an icecast server to receive and serve up that audio stream. With the pi connected to your home router (no internet needed), you can then browse using your phone or other device to the ip address of the pi (something like 192.168.0.XXX) port 8000 and play the stream on your device.Well I wanted to look into using a raspberry PI as a wifi server I have two or three scanners that I would like to use..I want to go direct and not use the internet. right now I have one scanner and use a radio tx transmitter they sell for putting cd or whatever into car auto systems. Have range about a block and a half. (it on a second story)..
