Currently, there are vast areas of HF spectrum that currently have absolutely zero ham radio signals. We don't need to use very narrow bandwidth signals when these conditions exist. It is "good amateur radio practice" to develop digital voice modes, at any bandwidth, and to explore the possiblities of new techniques. One of the techniques we should be exploring is the use of single-channel time multi-plexed digital voice repeaters on HF. Bonnie KQ6XA
