By request, the charts (up through 70 cm) now include a text listing of the channels.
Corrections or suggestions for improvements are welcome.
The NCPA does band planning and channel assignments within the digital segments (see Packet Band Plan).
In August 2006 the NCPA adopted the ARRL band plans for the bands above 70 cm.
In September 2009 the NCPA adopted the ARRL band plans for the bands below 2 m.
In June 2010 the NCPA adopted the ARRL band plan for the 1.25 m band.
In August 2017 the NCPA added three channels to the lower digital segment in the 2 m band, as per IARU.
The adoption of the ARRL band plans is currently under negotiations with other groups who are being asked to adopt it as well.
The ARRL is a member organization and the secretariat of the IARU and participated in the IARU band plans. However, as of this writing, there are some differences in the ARRL band plans and the IARU region 2 band plans. It appears the ARRL band plans simply haven't been updated recently. The HF and MF charts here are based on the latest IARU region 2 plans.
The MF band plan chart includes the 600 meter segment, although it currently is NOT an amateur band. 500 kHz was the international CW emergency mariner frequency, but that has been discontinued. There is a chance some of the 600 M segment will be allocated to amateur radio, just as the 160 M band was after LORAN A was abandon.
See 47CFR 97.303 for frequency sharing requirements.
