RAC Ontario Sections Bulletin for October 2, 2021
Official Bulletin Station for Radio Amateurs of
Canada, with this week's bulletin
1. HF Band Plan review
Over the past 18 months a proposal for an IARU HF Digital Mode
has been undertaken by representatives of all three IARU Regions
IARU-R1 reports: The objectives were to review the data modes usage of the
Amateur Radio HF spectrum and propose changes that:
• Reduce inter-mode conflict between dissimilar operating modes; and
• Facilitate the expansion of new technologies.
In conducting the review it was realized that it was necessary to update
in which the IARU creates its band plans. Accordingly, the IARU’s band
definition toolkit were redefined, and additional data mode definition
has been added to help separate activities that are fundamentally
within the data mode family.
With the band planning process updated, the proposal then revised the
band plans of
all three IARU Regions, focusing on the data sub-bands and taking into
• Popularity and capacity requirements; and
• Existing band users and inter-mode compatibility assessments.
The team also took the opportunity to harmonize the band plans of all
Regions to the greatest extent possible of course.
The proposal is now being discussed in the relevant committees.
