As the use of amateur radio grows in China, a new digital
mode has been developed that uses Chinese characters rather than the Western
European/American alphabet.
Southgate Amateur Radio News reports that the new mode is called CP-16
and is based on the 16x16 dot-matrix display used to generate Chinese
characters on computer screens. It uses 16 on-off keyed audio characters spaced
at 17-Hz intervals, resulting in a total signal bandwidth of less than 400 Hz.
Transmission speed is two-to-five characters per second and it can be received
on any software defined radio (SDR) receiver or SSB receiver/computer combination
running waterfall-display software. The characters will appear directly on the
waterfall display. More information is available at
