Chris Long VK3AML has produced a video showing amateur radio narrow band TV which uses just 10 kHz bandwidth.
The YouTube description reads:
VK3AML starts with a raw and rather fuzzy 32 line image, generated within a 10 kHz bandwidth. Improvements are introduced - (1) raising gamma to improve greyscale, (2) sharpening applied to webcam software prior to standards conversion to 32-lines, (3) high frequency boosting of 32 line wav file after standards conversion by applying FFT protocol in AdobeAudition V3 software.
The Standards Conversion Freeware necessary for converting video, avi or webcam to 32-line NBTV pictures can be found on Gary Millard's web page: http://users.tpg.com.au/users/gmillard/nbtv.htm
Gary's software is excellent, and has been used to excellent effect by the Narrow Band Television Association for several years.
