Sorry Tom, if bandwidth is the measure of relevance, CW has just lost
out. PSK (phase shift keying) is now available to any amateur with a
16-bit sound card in his computer and an SSB rig. The total bandwidth
required is an incredible 31 Hz. You can download the FREE software
at:
http://bipt106.bi.ehu.es/psk31.html
There are several versions available depending on your operating
system and soundcard. Most folks will probably want the one for
Windows and Soundblaster. Included is an extensive help file which
will get you started.
So back to your statement about relevance....
