How to Connect the rtl_433 to a remote rtl_tcp server

One of the issues with the rtl_433 application is that it is not possible to connect it to a remote rtl_tcp server using syntax supported by other SDR application like gqrx. One of proposed solutions is to use the TCP enabled version of the librtlsdr which is a bit complicated. There's actually a much simpler solution.

The easiest way to find out what protocol is used is to analyze signals with an oscilloscope of course but I didn't have one. So first of all I needed to implement a signal logging functionality.
