Narrow Band TV (NBTV)
10 February 2015 | by Partly because bandwidths are very low, there has been a revival of interest in NBTV systems similar to the early TV transmissions by Baird in the 1920s and 1930s.
There is even a Televisor kit available for about £40 delivered (in the UK) with a CD with some still and moving images and its own test card generator. I am quite tempted!
The televisor kit is available for £35.94 + shipping from http://www.mindsetsonline.co.uk/Site/Home (search for televisor). This is compatible with the 32 line standard of the NBTV Association. The NBTV Association home page is at http://www.nbtv.wyenet.co.uk/index.htm .
Bandwidths are audio only, so a tape recorder or CD are fine. Over the air transmissions only require audio bandwidths too. Of course, with just 32 lines don’t expect brilliant images!

I wonder if there is PC software to generate the NBTV for this display.
Yes there is PC software available. It is online and it does work very well. ZL1BPU website has the downloads.
I thought John Logie Baird’s tv system was mechanical not electronic.
