This site is dedicated to everyone world wide that has ever used 27 Mhz or the ELEVEN Metre Band! 
 
Also known as 27 Mhz Citizens Band CB radio & FREEBAND  which could be anywhere from 26.500 to 27.995 just below the Ham 10m Band.

We do not condone this, just see it as a fact of DX. Use of many of these frequencies is not legal in most countries if outside the regulation CB allocation.

Radios & Installation.

Boats shall be capable of transmitting/
receiving, as a minimum, on the following
frequencies:-


• VHF - International Channels 16, 72, 73, 80 and 81


• HF/SSB - 4483kHz and 6516kHz


and such other frequencies as the
Organising Authority may determine


Emergency aerials are required to have
their mounting brackets and cabling
permanently installed.


Boats shall provide a Radio Inspection
Certificate with the entry form where a current
certificate is not already held by the
Organising Authority. The Radio Inspection
Certificate is to be completed by an accredited
radio technician to verify the adequacy
of the installation and operation of the radios.
A boat in the Cruising Division that does not
have an HF/SSB may seek a dispensation
from the Race Committee by demonstrating
that it has another satisfactory method of
contacting the Organising Authority, such
as by satphone or by email via SATCOM C,
D+ or other system.
Pre-race radio check
Boats shall carry out a radio check on 4483
and 6516kHz between 15 December
2009 and 22 December 2009 with an
organisation to be advised to entrants at a
later date.
 

The organisation conducting the radio
checks will monitor these frequencies
between 0800 hours and 1800 hours
during that period. Radio checks will not be
approved outside of these hours.
Boats not recorded as having adequate
radio signal strength will not be eligible to
start.


Operation
Boats shall maintain a 24 hour listening
watch for the duration of their race on VHF
Channel 16.
For radio communications, a boat’s name
may be limited to not more than two words.
The Race Committee may alter names
where appropriate.
The Sailing Instructions will require that
boats report by radio when they are in
the vicinity of Green Cape and make a
declaration confirming their time of passing
as well as the following:
• The HF radio is operational
• Liferaft(s) are on board
• Engine and batteries are operational
• Boat and crew are in a satisfactory
condition to continue
• The skipper has comprehensively
considered the most current weather
forecast and the boat and crew are fully
prepared for the conditions forecast.
Boats which are not recorded as having
met the reporting requirements above shall
be disqualified without a hearing (amends
RRS 63.1).
Boats that make a false report will be
subject to action by the Race Committee in
accordance with RRS 60.2(c).

The frequencies used for marine communications are internationaly agreed by the International Telecommunication Union (ITU). Below you will find a list of HF frequencies. In the main most frequencies are Duplex and intended for ship to shore use. Some bands do have simplex channels which can be used for either ship to shore or intership working.
