Mode Band Plan Review
following was posted by K1ZZ, Dave Sumner, as an IARU News
Because frequency allocations and amateur radio operating
interests vary in different parts of the world, the
development of band plans – voluntary guidelines on the use
of the spectrum that is available to radio amateurs – is a
responsibility of the three IARU regional organizations.
Each of the three Regions has a band planning committee to
focus on this work. In recent years there have been
increased efforts to bring the regional band plans into
alignment wherever possible. Final approval of band plan
revisions is generally given by the regional conferences of
IARU member-societies that are held every three years on a
approach to band planning generally has kept pace with the
evolution of amateur radio operating. However, the explosive
growth in HF (below 30 MHz) digital modes, particularly FT8,
has led to perceived overcrowding of HF digital mode band
segments. Accordingly, a working group has been formed
consisting of representatives of the three regional band
planning committees. This is the first time the three
Regions have joined together to directly coordinate band
working group has already had fruitful discussions with the
WSJT Development Group led by Joe Taylor, K1JT. Additional
discussions, including with other HF stakeholders, will be
held as part of a fundamental review of the different HF
digital modes, and how they can be best categorized and
arranged to share the limited spectrum available.
main aim is to develop solutions that reduce congestion
within very popular mode segments while preventing mutual
interference between incompatible modes to the greatest
extent possible. While the proposed band plan revisions will
have to be approved by member-societies in each Region,
recent administrative changes mean that the changes can be
implemented without having to wait for the regional
