Issues:
1.
Presently, there is a general misuse of VHF-FM marine band frequencies by
vessel operators throughout the
2.
Presently, there is a growing problem with radio interference on VHF-FM
communications in
Discussion.
1.
Historically,
2.
The VHF-FM interference will continue to
worsen as cellular and paging transmission increase.
This is a complex issue. The
interference is understood to be a result of “spurious harmonics” created
primarily by the amplification of cellular phone and paging transmissions.
Several speakers have addressed HOST and have identified possible
solutions including the upgrading of VHF radios currently in use,
or the use of specialized
antennas.
3. In February, 1998 HOST issued Safe Operating Practice 6-98 which created a VHF-FM Frequency List used by all commercial operators. The original SOP format listed all frequencies by Operator and Island which was found to be confusing and very difficult to keep current.
Recommendations
of HOST:
1.
Create a frequency plan that lists frequencies used by all commercial
operators operating from Hawaii’s commercial ports. List the
frequencies by “Function” and “Channel” rather than by “Operator.”
3.
Continue to investigate ways to reduce VHF-FM/microwave interference in
Honolulu Harbor.
4.
Capture the frequency plan and any proven methods to alleviate
VHF-FM/radio interference in the HOST Standard Operating Procedures Handbook.
Resolution.
Representatives from industry, vessel agents, Aloha Tower, USCG, Hawaii
Pilots Association, Hawaii State Pilots, and State Harbor Masters have provided
input for the frequency plan. The
following enclosed documents have been approved by HOST.

Marine
Radio Etiquette
Maintain a watch while the radio is turned on,
even though you are not communicating. Monitor the call and distress channel 16.
Choose the correct channel when communicating
ship-to-ship or ship-to-shore. Channel 16 is a hailing and emergency channel
only but it's the most abused channel. This channel is not for chatting or idle
conversation. After contacting another station on channel 16, change immediately
to a channel that is available for the type of message you want to send.
Limit the preliminary call to 30 seconds. If there is no
answer, wait 2 minutes before repeating the call. If you don't get a reply after
two attempts, try to establish communications later.
Limit ship-to-ship
conversations to 3 minutes and the content
to ship's business. Be considerate of others, they may want to use the line.
Conversations should be brief and to the point.
Never use profane or obscene
language or transmit fraudulent
messages. Penalties include fines up to $10,000 and/or imprisonment.
The marine radio is not a
citizens band (CB) so
don't use phrases such as "That's a big 10-4", "come back."
You are strongly encouraged to use "procedure" words. These shorten
the length of the message and eliminate confusion. Remember to use
"over" when you expect a reply. Use "out" when you are
finished. Roger means, "yes I understand." Wilco means, "both
Roger and I will do that or I will comply." Affirmative is "yes"
and Negative is "no."
Listen before transmitting for about 30 seconds to
determine if the channel is in use. Speak clearly in a normal tone of voice and
hold the microphone about an inch from your mouth.
Use FCC call signals and/or your vessel's name at
the beginning and end of all transmissions.
Use minimum radio power (one watt) when possible. This
will reduce the distance the signal carries beyond your target.
Children should never be permitted to
use the radio as a toy.
Need to send a distress call?
You may only have a few seconds.
Here's
the procedure to follow. Transmit in this order:
1.
Tune your VHF to channel 16.
2.
Repeat the word
"MAYDAY," three times.
3.
Say "this is (name the
boat)." Repeat the boat name three times.
4.
Give position by latitude and
longitude or by bearing and distance to a well-known landmark or navigational
aid, or in any terms that will assist a responding station in locating the
vessel in distress. Include any pertinent information, such as vessel course,
speed and destination.
5.
Indicate the nature of
distress (sinking, fire, etc.).
6.
Indicate the kind of
assistance desired.
7.
Describe your boat size, rig
type, color and tell the number of persons aboard.
8.
End with "over."
VHF-FM RADIO COVERAGE OF THE
HAWAIIAN ISLANDS
The
accompanying page to this article outlines VHF-FM radio network coverage
emanating from the VHF-FM hi-sites located on the Kauai, Oahu, Maui, and Hawaii.
As indicated on the diagram, the hi-site coverage areas overlap each
other to provide overall excellent offshore coverage.
However, primarily due to VHF line of sight characteristics and
geographic obstructions, there are certain areas where zero to marginal VHF
communications can occur. These
areas, as noted by slash marks on the outline, usually extend from shoreline to
approximately five nautical miles.
