1.36 to examine the adequacy of the frequency allocations for HF
broadcasting from about 4 MHz to 10 MHz, taking into account the
seasonal planning procedures adopted by WRC-97

Introduction

It has been evident for several decades that the spectrum available to
the broadcasting service between 4 and 10 MHz is inadequate. The bands
are ideal for short- and medium-range coverage (up to 2 000 km) during
daytime and are also needed to support longer-range services at night.
In recent years, there has been a tendency for many broadcasters to
improve the reliability of their transmissions by using short-distance,
single-hop transmissions in the lower frequency bands to replace their
long-distance, multi-hop services.

Since 2000, a comprehensive study of the use of the HF bands for
broadcasting, aided by the better information now available through the
regional coordination arrangements introduced by WRC‑97 as part of RR
Article 12, demonstrates that the total shortfall in spectrum in the 6,
7 and 9 MHz broadcasting bands is at least 250 kHz. That is if the
objective is limited just to eliminating co‑channel collisions.

However, up to 800 kHz would be needed to eliminate adjacent channel
collisions. Practical experience in planning confirms these analyses and
recommendations. These conclusions are remarkably similar to the
estimate of a 700 kHz shortfall contained in proposals submitted to
WARC‑92.

WRC-03 is fully competent to reach closure on reallocation issues in the
4-10 MHz portion of the HF band. The expected use of this portion of the
HF band is not expected to change in any practical way between 2003 and
2007-2008. All necessary studies of consequence have been completed by
the affected Study Groups and the SCRPM to enable WRC-03 decisions on
this 6 MHz of spectrum, thus there is no need for preliminary agenda
item 2.5 at WRC-07.

The United States proposal is consistent with the CPM Report for total
spectrum required for eliminating the shortfall in spectrum if the
objective is limited to just eliminating co-channel collisions. The
total additional spectrum proposed is 200 kHz for Region 2, and 250 kHz
for Regions 1 and 3. The regional difference is due to 50 kHz being
proposed in Region 2 at the 7 MHz band, whereas 100 kHz is proposed at 7
MHz for Regions 1 and 3.

This proposal includes modifications to four fixed service bands: one
just below 6 MHz, one just above 7 MHz and two above 9 MHz. The
selection of this amount among the various fixed service

allocations was governed by two considerations: 1) to spread the new
allocations for HFBC into frequency bands adjacent to where the maximum
amount of interference exists; and 2) to do this in a way that affects
the fixed service only with relatively small fractions of the current
amount in its bands below 10 MHz under consideration.
