IARU Region 2 HF Band Plan

The IARU has voted to adopt a HF bandplan based on signal bandwidth. This looks like the previous ARRL proposal somewhat. Below is the text of the bandplan taken from http://www.iaru-regionii.org/Region_2_MF__HF_Bandplan_2008.pdf





IARU REGION 2 MF/HF BAND PLAN – Effective January 1st 2008
The IARU Region 2 has established this band plan as the way to better organize the use of
our bands efficiently. To the extent possible, this band plan is harmonized this with those
of the other regions. It is suggested that Member Societies, in coordination with the
authorities, incorporate it in their regulations and promote it widely with their radio
amateur communities.

Explanations
Bandwidths
The number in the bandwidth column always refers to maximum allowed bandwidth.
Preferred Modes
All modes Do not exceed the specified bandwidth.
Image The Image mode includes FAX and SSTV.
Narrow band modes All modes up to 500 Hz bandwidth including CW, RTTY, PSK
and others.
Digimodes Includes, but not limited to PSK31, PSK63, RTTY, MT63 (within
bandwidth limits).
Sideband usage: Below 10MHz use lower sideband (LSB), above 10MHz use upper
Sideband (USB).
Notes
CW QSOs are accepted across all bands, except within beacon segments.
Contest activity shall not take place on the 10, 18 and 24 MHz bands.
The term “automatically controlled data stations” includes Store and Forward stations.
Transmitting frequencies:
The announced frequencies in the bandplan are understood as “transmitted
frequencies” (not those of the suppressed carrier!)
Unattended transmitting stations:
IARU member societies are requested to limit this activity on the HF bands. It is
recommended that any unattended transmitting stations on HF shall be activated
only under operator control except for beacons agreed with the IARU beacon
coordinator, or specially licensed experimental stations.

Please note that the above band plan (incl. the PDF) contains some errors.

Addtionally IARU Region 2 has relauched its website, which can now be found at http://www.iaru-r2.org.

The corrected version of the band plan can be downloaded here: http://www.iaru-r2.org/band-plan/
