Yaesu supports 4-FSK digital radios

Since 2005 both ICOM and Kenwood have been producing comercial VHF/UHF rigs and repeaters using 4-FSK modulation now Yaesu has announced its support for 4-FSK (C4FM).

Yaesu's new publication 'A Digital Communication Guide for Amateur Radio operaators' can be seen at

It is not widely realized that the D-STAR standard includes the spectrum efficient 4-FSK as well as GMSK.
