WARC 2007 - World Radiocommunications Conference.
Shortwave broadcasters such as the BBC and defense users such as the
United States Navy are expected to battle over spectrum used for high-
frequency communications in the 4 to 10 MHz bands at the upcoming World
Radiocommunications Conference.

Broadcasters may lose battle to expand 4-10 MHz allocation.
On 22 October, 190 nations will gather in Geneva for the quadrennial World
Radiocommunication Conference, which allocates global radio frequency
spectrum. Richard Russell, the US ambassador to the conference, describes
it as the Spectrum Olympics.
It's already looking as if shortwave broadcasters will lose the battle
with military users over spectrum used for high-frequency communications
in the 4 to 10 MHz bands, Russell said. The broadcasters want to use this
band to replace their analogue broadcasts DRM services. But the US Navy
wants to use the HF bands - underutilized since the demise of Morse code -
to support the broadcast of data over new IP-based services at far less
cost than sending data by satellite.
Russell said that except for the European Union, countries are heading
into the WRC aligned with the US position to not allow an expansion of
shortwave broadcasting in the HF band.

Some facts and figures on required additional spectrum for broadcasters 4
- 10 MHz.
In response to our earlier report quoting the US ambassador to the World
Radiocommunication Conference, we have received the following response
from Jan Verduijn, CEPT coordinator and European spokesman on Agenda Item
1.13:
"In a press release Mr Richard Russell, the US Ambassador to the
forthcoming World Radio Conference, states that the shortwave broadcasters
will lose the battle with the military users for their extra broadcasting
requirements in the band 4 - 10 MHz. However, the arguments used by Mr
Russell are very wrong and misleading.
The real situation:
"Already for years the shortwave broadcasters have had enormous problems
satisfying their requirements below 10 MHz. To have a good indication for
these requirements, WRC-2000 requested the broadcasting community to show
at WRC-2003 full details of their requirements in the frequency band 4 -
10 MHz.
"This resulted in a decision of WRC-2003 via Resolution 544 to ask for 250
kHz to solve the co-channel interference and up to 800 kHz to resolve both
the co-channel and adjacent channel interference. This is the real reason
that the broadcasters are asking for additional spectrum and not to
replace analogue with digital transmissions. This Resolution 544 is,
