    Note:

    ? Considering the dramatic increase in data mode usage on the 20 meter band, it

    is recommended that the sub-band for these classes of signals be 14.070 MHz

    to 14.112 MHz (with +/- 500 Hz at 14.100 MHz for beacons), and within that

    data sub-band the current practices of traditional data modes may continue up

    to 14.095 MHz with 14.095 to 14.112 MHz being reserved for other data

    modes including Packet.

Bands above 1300 MHz:

    Societies should consult with the amateur satellite community for proposed satellite

    operating frequencies before deciding local bandplans above 1300 MHz.

The Basic Principles Underlying the IARU Region 3 Bandplan:

    (1) In all cases of conflict between a bandplan and the national regulations of a

    country, the latter shall prevail.

    (2) Nothing in these bandplans shall be construed as prohibiting different national

    arrangements, provided that harmful interference is not caused to stations in countries

    operating in accordance with the regional bandplan.

    (3) Notwithstanding item 2 above, Member Societies of IARU Region 3 are strongly

    urged to use these regional bandplans as a basis for their national bandplans.

[Legends]

CoA: Emergency Centre of Activity frequency

    EME: Earth-Moon-Earth, Meteor Scatter, Auroral Scatter and other weak-

    signal

     NB: Narrow band modes including CW, RTTY, Packet and modes with

    similar bandwidth not exceeding 2 kHz. Phone: Phone operation includes SSTV, FAX and modes with similar

    bandwidth not exceeding 2 kHz. Satellite: This segment should be kept clear of other operating modes.

    Secondary: At 7.2 to 7.3 MHz, amateur stations shall not cause harmful

    interference to stations of the Broadcasting Service. WB: Wide band modes including FM.
