Amateur television

One of the aspects of our hobby I have never tried is ATV apart from SSTV reception. My SSTV reception was with some free software using a smartphone on the desk. It worked surprisingly well. 

There used to be some interest in narrow band TV (30 or 32 lines) that used ordinary speech bandwidths much like the very early days of TV. 

These days there is quite a bit of interest in digital TV as the bandwidths are narrower and we have some experimental frequencies near 70 and 144MHz. One local has been building the Portsdown 4 transceiver based on the Raspberry Pi.
