THE 30M BAND UTILIZATION CHART
The "30m Band Utilization Chart" is exactly that. It is not a "bandplan", nor even an "unofficial bandplan". Rather, it is an attempt to graphically portray the many modes that are actually in use on 30m today. There is a clear distinction between dial frequencies and emitted frequencies, helping you to accurately set the correct frequency and to identify signals as they appear on the waterfall.
Note, however, that the three IARU Region Bandplans specify the following bandwidth limits in the 30m band:

KEY TO COLOR CODING
Yellow boxes indicate ranges of emitted frequencies, with no dial frequencies. Activity takes place anywhere within these boxes.
Gray boxes, with associated dial frequencies, are (more-or-less) "fixed" frequencies of operation, and the dial frequency is what you use with the software packages generally available. In the case of AX.25 packet, the dial frequency assumes 1600/1800Hz (KAM) tones.
Dark green boxes indicate analog modes.
Blue box indicates commercial station.
