30 line image.
Attempt at showing an image. One problem is that while the fluorescent tube provides a bright white raster, the phosphor persistence turned out to be unsuitable - what you see as brown should be black. The linearity of modulation may also be questionable.
The source of the signal is a wav file from the NBTV organisation who have standardised on 32 lines (convenient for digital dividers). This gives a rolling image when displayed on Baird standard televisors.
