Expensive Handheld VHF Radios: Standard Horizon Edges Icom
With its solid performance, multi-band reception, and DSC emergencycalling capability, the Standard Horizon HX600S takes top honors. The radios from Icom had the longest battery life.
andheld VHF radios come in handy for a variety of tasks aboard any boat. On small skiffs, they serve well as the main method of communicatingand you dont have to worry about the mounting, antenna, and wiring issues associated with a fixed-mount radio. On larger vessels with a fixed-mount VHF already installed, handhelds can serve as a viable backup radio or as a means of two-way communication if the dinghy is launched. When used as a backup, your handheld can even connect to the boats main antenna via an adapter and significantly increase your transceiver range.
of handheld VHF radios into two groups. In this review well report on upper-echelon units that sell for more than $175. Next time, well cover less expensive radios. Our lineup includes two units from perennial VHF leader Icom (models IC-M72 and IC-M88), four from Standard Horizon (models HX370S, HX500S, HX600S, and HX471S), the Ray101 from Raymarine, and the West Marine VHF 250.

How We Tested

The first order of business was to charge the batteries, which we did using the associated AC chargers. Next, we ran each radio through a series of bench tests, including transmitter power output, frequency accuracy and stability, and receiver sensitivity. We used a sophisticated piece of radio test gear, a Ramsey COM3010 com-
munications service monitor. Maximum power output on a portable handheld marine radio is limited to 5 or 6 watts. A low-power setting, 1 watt, for harbor use, is also available. In addition to the high- and low-power settings, most of the radios we tested had a midpower setting. We tested only at the max power and 1 watt. We took transmitter power measurements directly off the radio antenna port located on the top of each radio. Frequency accuracy is defined as Below, from left to right: Standard Horizon HX471S, Icom IC-M88, Icom IC-M72, West Marine VHF 250, Standard Horizon HX500S, Standard Horizon HX600S, Standard Horizon HX370S, Raymarine Ray101.

the ability of the transmitter to send signals out on the selected frequency. Frequency stability measures the transmitters ability to maintain frequency accuracy over its entire temperature operating range. Regulations mandate an accuracy of 10 parts per million, while industry groups typically call for half that error. This equates to being about 1550 hertz (Hz) off frequency in the marine frequency band. Each transmitter test was done on channel 16 at room temperature (75 F), as well as temperature extremes near the maximum ranges of each radio. To reach the cold extreme, each radio was put in a bait freezer at 15 F for four hours prior to testing. We used a fish smoker as an environmental chamber to get the radios to high-temperature extremes. Each
was left to cook for two hours at 122 F and then immediately run through another transmitter-power and frequency test. We also checked each units lowpower setting, measuring both power output and frequency accuracy. Frequency stability was rated over the entire range of transmitter testing; the closer a unit held to the appropriate frequency, the higher it was rated. Receiver sensitivity is the ability of the radios receiver section to hear a weak signal. Typical marine VHF receiver sensitivity ratings run from.22 to.35 microvolts, with industry groups recommending a minimum.50 microvolts. Each radio receiver was tested for the minimum signal it could receive at a specific industry standard setting between background noise and generated signal (12 dB SINAD). All the radios rated Good or

better, meaning they are more than sensitive enough to pick up very weak incoming signals. Another receiver standard is selectivity, the ability of the receiver to reproduce only the signals you want to hear, and not others, even though they may be strong and nearby. Our test equipment did not allow us to test each radio for this characteristic. Each manufacturer provided information, which is listed in the chart under selectivity; a higher number is better. Display ratings were based on the size of the channel number display, the amount of other information shown, the value of the channel comments, the size of the screen, and the quality of the backlighting. One important part of the marine radio often overlooked is the audio amplifier and speaker. Boats can be

drop test to confirm the radios survivability. Each radio was turned on then dropped from a height of 4 feet onto concrete. Again, all of the radios passed this test. The clock started ticking for the battery-life test immediately following charging. We allotted the first hour of use to run our bench tests. Radios were off during their time in our environmental chambers and then turned back on the following day and allowed to run continuously for the next 14 hours. We transmitted at full power for about three minutes every hour and received voice signals for about five minutes every hour until the battery died or the unit began to malfunction. Total battery test time was 15 hours. Radios still fully functional at that time were rated at 15+ hours of battery life. In the final analysis, we considered performance, cost (initial and battery replacement), warranty (both unit and battery), battery life, included equipment, recharge time, display, and audio output.

Icom IC-M72

Ergonomically, the IC-M72 tops the field. Its lightweight, fits into one hand well, and is comfortable to hold and use. The most powerful battery in the field provides the muscle for a sixwatt transmitter, the highest output power rating of any handheld VHF weve tested. Tested battery life was excellent with the transmitter still

noisy places, and if you cant hear the output, it doesnt really matter how well the transmitter or receiver works. To rate the audio system of each radio, we measured the sound pressure at maximum volume while generating a 1 KHz tone with the COM3010 and inputting the tone into the radio. Measurements were taken at a distance of 1 foot using a Radio Shack decibel meter. Our tester also rated each audio system with a voice input by monitoring a weather channel and rating the quality of sound reproduction. A submersion test was conducted on each radio to confirm it as waterproof. The tester turned on the radios and submerged them in a bucket of fresh water for 30 minutes. After Right: We used a Ramsey COM3010 communications service monitor to record and rate transceiver specifications.
removal, we checked the radio for proper operation immediately and then again the next day. All of the radios passed this test. Since a user typically carries a handheld radio either in hand or on a belt clip, we elected to perform a
pumping out plenty of power even after 15 hours of use. One downside: Replacing the battery will cost you nearly as much as the radio itself: $130. Overall performance ratings on the IC-M72 were Good to Excellent, though it fell a bit short in two areas. It scored only a Fair for transmitter frequency stability because the transmitter went off frequency by a small amount after emerging from the heat chamber. It was still within design specifications and completely usable, however. Following submersion, we noticed the battery compartment had some minor water intrusion. According to Icom advertising manager, Dave Kruzic, water in the battery area is not a problem for Icom radios. There is no huge gasket between battery and radio to prevent water intrusion. Where it is important to protect against water intrusion is where the battery contact points meet the radio mainframe. If you look at both the M72 and M88, the gasket is small and only covers this critical area. If you submerge the radios with the battery properly fitted in place, remove from water and shake the radio off, you should hear a small suction snap when removing the battery and the contact point seal is disrupted. It should be dry in that small area. The rest is unimportant. This radio is operated with a rotary on/off/volume control located on top,
a push-to-talk and a squelch button on the side, and six pushbuttons on the front panel. Controls on the front select transmitter power, channel changing, weather, quick 16 or 9, and scanning. An optional microphone or speaker connects through a port in the top. Bottom Line: A well-built radio with highly rated ergonomics, good performance, and excellent battery life. Battery replacement cost is high.
as to why water in the battery area is not a big deal. Bottom Line: A great performer, but its expensive and so is battery replacement.

Raymarine Ray101

At about twice the size of the diminutive Icom M88, the Ray101 is the heftiest handheld in this test. It uses six AA-size nickel metal hydride batteries contained in a sealed battery pack that fits securely to the back of the unit. This setup gives the Ray101 the lowest battery replacement cost in the group, as well as the opportunity to quickly install standard AA batteries should the need arise. Unfortunately this setup also yielded the worst performance in our battery life test by only lasting nine hours. Raymarine communications manager Nancy Baumgartner commented on the Ray101 batteries. Since the battery is a consumable item, it is not covered under the 3-year radio warranty. One of the major advantages of the Ray101 is that it does not use a proprietary battery pack; instead the consumer can go to any retail store in the US and buy regular AA rechargeable NiMH batteries for a fraction of the price of the proprietary custom batteries used by other radio manufacturers. Ray101 also allows flexibility for the users to upgrade their batteries to the bigger capacity battery. Upgrading to the bigger capacity battery would instantly increase the battery life and make the radio up to date to the latest battery technology. Two rotary knobs are mounted on the top of the unit: an off/on/volume control and a squelch control. The side-mounted, push-to-talk switch is too hard to press, in our opinion. Seven front panel pushbuttons select transmitter power, scanning options, channel change, weather, panel backlighting, and quick 16. Left: A few drops of water got inside of the Icom IC-M88s battery compartment after our dunk test, but a gasket protects the battery-to-radio connection.

Icom IC-M88

This expensive sub-compact packs a load of features into a lightweight package about the size of a bar of soap. The M88 operates by using the rotary on/off/volume control located on top, a push-to-talk and a squelch button on the side. Six front-panel pushbuttons control transmitter power, channel changing, weather, quick 16 or 9, and scanning. An optional external speaker/microphone plugs in on the side. The M88 earned Good or Excellent ratings across the board. During the battery-life test it was one of only four radios still functioning after 15 hours and it was going strong even then, pumping out plenty of transmitter power during our final check. This radio shares two less-than-desirable traits with its sibling, the M72: It has a very expensive battery ($122) and it had some water in the battery area following our dunk test. See the Icom IC-72 text for Icoms explanation
Overall performance of the Ray101 was Good. We found water in the battery area after the dunk test. It did not penetrate the battery compartment or the area where the battery-to-radio connections are located as they are protected with a small gasket. Bottom Line: Too big and heavy for our liking, plus it has a rather short battery life.

Standard Horizon HX600S

The HX600S is the product line leader for Vertex Standard. It features multi-band and digital-selective-calling capabilitiesone of only two radios with the latter feature. If it is sitting in its charger and the charger is wired to a GPS unit, the HX600S will transmit vessel position data along with the MMSI number when making an emergency Digital Selective Call (DSC). The HX600S has a top-mounted volume control and side-mounted pushbuttons for on-off, squelch, and push-to-talk. Eight front-mounted pushbuttons control transmitter power selection, channel changing, weather, scanning, and band choice. It can receive signals on the Marine, Aircraft, AM, and FM bands. It transmits on Marine only. An optional headset, microphone, or speaker plugs into a jack on the top of the unit. The HX600S was the only radio to achieve Excellent ratings across the board and pass the drop and submersion tests with no glitches or caveats. Battery life was also Excellent and rated at 15+ hours. Battery replacement cost, at $65, is the lowest of any unit that requires a specialized battery. Bottom Line: Excellent performance coupled with features like multi-band technology and DSC capability make the HX600S our top pick.
Above: Standard Horizon packs a smorgasbord of features into its HX471S. Here, the radio is set on the Aircraft Band, which would allow a boater in trouble to monitor aircraft search-and-rescue communications. side-mounted pushbuttons for onoff, squelch, and push-to-talk. Seven front-mounted pushbuttons control transmitter power selection, channel changing, weather, and scanning. An optional headset, microphone, or speaker plugs into a jack on the top of the unit. The HX500S performed very well in our testing, earning mostly Excellent ratings. It passed the drop and submersion tests. Though it uses the same battery as the HX600S, it did not perform quite as well, lasting 13 hours. When we ended its battery-life test, the HX500S was not deadit simply stopped transmitting just seconds before it would have been set aside for another hour. The HX500S has a cutout circuit that will lock out the transmitter when the battery voltage drops below a certain point. It still had life and could transmit, just not for the sustained 3 minutes we used during our testing. Battery replacement cost on the HX500S is $65. Bottom Line: Rugged construction, very good overall performance, and a reasonably priced replacement battery make the HX500S a good choice. HX500S and HX600S, it is bigger and heavier. It also has a larger display screen. The HX370S has a top-mounted on/off/volume control and sidemounted pushbuttons for push-totalk and squelch. Seven pushbuttons on its face control transmitter power selection, channel changing, weather, and scanning. An optional headset, microphone, or speaker plugs into a jack on the top. The HX370S performed well in our testing, earning all Good and Excellent ratings. It did, however, trail most in the group in audio output. Submersion testing went well. The battery separated from the radio during the drop test, however. After we picked it up and reinstalled it, everything was operating normally. Battery life on the HX370 was rated at 15+, though upon reaching hour 15 it was fairly weak. We dont think this radio had much left at that point. Battery replacement is $65. Bottom Line: A decent overall performer; its just a little big and heavy for us.

receives voice traffic on the Marine, Aircraft, Family, AM, FM, MURS, and Aircraft bands. It can transmit on Marine and Family radio channels. During a DSC emergency call, it will transmit the vessels MMSI number andif configured properlywill relay position data in lat/long. HX471S has top-mounted volume and squelch knobs and a side-mounted pushbutton for push-to-talk and backlighting. Front-panel pushbuttons control transmitter power output selection, channel changing, weather, scanning, band choice, and a quick 16. An optional headset, microphone, or speaker plugs into a jack on the top of the unit. The HX471S performed well in our tests, earning mostly Good ratings. We noted no problems during the drop or submersion tests. Battery life on this radio was rated for 13 hours, well beyond the manufacturers 10to 12-hour claim. One thing to keep in mind: When this radio dies from
a low battery, it is completely dead and will require a charge before it will come back to life. Recharge time on the HX471S is the fastest in the groupthree hours. Battery replacement is $83. Bottom Line: This radio has a ton of features packed into a small package. Performance was middle of the pack.

West Marine VHF 250

In addition to full marine-band capabilities, the multi-talented VHF 250 can receive signals from the Family radio, AM, FM, and Aircraft bands. It can transmit on Family radio channels too. Other features include a diecast metal case and a top-mounted adapter ready to accept an optional head set, speaker, or microphone. A scrambler is optional. The VHF 250 is controlled with a pair of top-mounted knobs for on/off/ volume and squelch, as well as seven front-panel pushbuttons for selecting the operating band, channels, weather, scanning, or quick 16 or 9. On the side is an easy-to-operate, push-to-talk switch and a backlit on-off switch. Overall performance of the VHF 250 was Good, but the audio system was weak compared to the competition. Testing took its toll on this radio. The internal connection between the unit and the antenna failed and the antenna mount was noticeably loose. In our battery-life test, the VHF 250 lasted 14 hours, well beyond its 10hour claim. Bottom Line: Lots of features in a reasonably priced package. A weak antenna mount holds this one back.

Above: The push-to-talk button on the side of the Ray101 was harder to press than any other test radios button. ner in every category. Certain radios excel in particular areas, while others provide all-around good service. We rated the Standard Horizon HX600S our top pick because it performed wellwith no hiccupsand had a bevy of added features, including the ability to listen on several voice bands and transmit a DSC call in an emergency. It is certainly not the smallest, lightest, or least expensive handheld out there, but when viewed as an overall package we think its the best. If youre looking for a radio with the longest battery life, wed opt for an Icom radio, either the IC-M72 or the IC-M88. Both had plenty of juice left at the end of our grueling battery life test. Technology enthusiasts trying to stay on the edge should look at the Standard Horizon HX471S. It packs all the features one could want into the smallest and lightest package weve tested. n Standard Horizon, 714/827-7600, standardhorizon.com Icom, 425/454-7619, icomamerica.com West Marine, 800/BOATING, westmarine.com Raymarine, 800/539-5539, raymarine.com

Conclusions

In this price range, you have plenty of options when choosing a handheld VHF. No unit stands out as a clear winAbove: The Standard Horizon HX600S fared well in every aspect of our evaluation.

3. ABOUT THIS RADIO

3.1 ABOUT THE VHF MARINE BAND
WARNING: The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with NOAA Weather stations available between 161 and 163 MHz. The marine VHF band provides communications over distances that are essentially line of sight Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 25W radio transmission expected distances can be greater than 15 miles, for a portable 5W radio transmission the expected distance can be greater than 5 miles in line of sight. The user of a Marine VHF radio is subject to severe fines if the radio is used on land. The reasoning for this is you may be near an inland waterway, or propagation anomalies may cause your transmission to be heard in a waterway. If this occurs, depending upon the marine VHF channel on which you are transmitting, you could interfere with a search and rescue case, or contribute to a collision between passing ships. For VHF Marine channel assignments refer to page 47 section 16.
3.2 ABOUT FRS (FAMILY RADIO SERVICE)
FRS is a private, two-way, very short-distance voice communications service for facilitating family and group activities Areas of Operation You may operate your FRS radio in the United States and certain locations specified by the FCC [95.192]. If you want to use FRS aboard a vessel or aircraft owned or operated by a U.S. citizen or company, you will need permission from the captain of the vessel. You must share the channel with other users [95.191(b)]. There is no meaningful way to share the channel with others unless you listen before transmitting and wait until the channel is available before you transmit. To listen

3.3 ABOUT RECEIVE ONLY CHANNELS and FREQUENCIES
AM/FM Broadcast Bands The AM/FM bands contained within the HX471S are the same channels you use every day to listen to music, news and commentary with your car or home stereo. The AM broadcast band currently extends from 530 to 1700 kHz. Channels are spaced in even 10 kHz increments; i.e.: 530, 540, 550,. , 1600 kHz in the United States and Canada. Elsewhere, channels are spaced in 9 kHz increments, i.e.: 531, 540, 549, etc. The FM broadcast band in the United States extends from 88 to 108 MHz. Channels are assigned at 200 kHz increments; i.e.: 88.1, 88.3, 88.5,. , 107.9. The channels from 88.1 to 91.9 are reserved for noncommercial educational stations. Outside the United States and Canada, the boundaries and channel spacing vary. In Japan, the band starts at 76 MHz. In Western Europe, the band generally runs from 88-108 MHz, but channels can be irregularly spaced, i.e.: 101.25 MHz. AIR (Aircraft) Bands The AM VHF aeronautical communications band lies between 108.000 MHz and 136.975 MHz. This frequency spectrum can be divided into a lower and upper range. The lower range between 108.000 MHz and 118.000 MHz is primarily used for navigational aids such as the ILS Instrument Landing Systems, DME - Distance Measuring Equipment, and VORs - Very High Frequency Omni Range. The lower range offers very little in the way of voice communications, it does however provide someone with a working knowledge of Morse code the opportunity to identify various beacons. The upper range of the aeronautical band 118.000 MHz to 136.975 MHz is where the majority of voice communications can be monitored. Communications in the VHF band are transmitted in AM mode and most if not all compatible receivers automatically default to this mode. Frequencies within the aeronautical range are spaced in increments of 25 kHz, as such you will find transmissions at 118.000, 118.025, 118.050 MHz etc. The frequency(s) you monitor will determine the nature of traffic you will hear. As previously mentioned frequencies in the lower range of the aeroPage 10 HX471S
nautical band are mostly occupied by navigational equipment and transmit non voice signals in Morse code. If you select a frequency in the upper range the air is suddenly filled with conversations between pilots and air traffic controllers, pilots and their company dispatchers, flight service stations, and ATIS broadcasts. Frequencies within the aeronautical band are designated according to their usage. Refer to the page 23 for operation.

4. GETTING STARTED
If the radio has never been used, or its charge is depleted, it may be charged by connecting the CD-25 Charger Cradle with the NC-72 battery charger, as shown in the illustration. If 12V DC power is available, the optional E-DC-19 DC Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable may be used for charging the battery. The NC-72, E-DC-19 and E-DC-6 will charge a completely discharged FNB-80LI battery pack in about 3 hours.
4.1 BATTERIES AND CHARGERS
The FNB-80LI is a high performance Lithium-Ion battery providing high capacity in a very compact package. CAUTION To avoid risk of explosion and injury, FNB-80LI battery pack should only be removed, charged or recharged in non-hazardous environments. 4.1.1 BATTERY SAFETY Battery packs for your transceiver contain Lithium-Ion batteries. This type of battery stores a charge powerful enough to be dangerous if misused or abused, especially when removed from the transceiver. Please observe the following precautions: DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals that power the transceiver can cause sparks, severe overheating, burns, and battery cell damage. If the short is of sufficient duration, it is possible to melt battery components. Do not place a loose battery pack on or near metal surfaces or objects such as paper clips, keys, tools, etc. When the battery pack is installed on the transceiver, the terminals that transfer current to the transceiver are not exposed. The terminals that are exposed on the battery pack when it is mounted on the transceiver are charging terminals only and do not constitute a hazard. DO NOT INCINERATE: Do not dispose of any battery in a fire or incinerator. The heat of fire may cause battery cells to explode and/or release dangerous gases.

Page 12

Battery Maintenance For safe and proper battery use, please observe the following: r Battery packs should be charged only in non-hazardous environments; r Use only STANDARD HORIZON-approved batteries; r Use only a STANDARD HORIZON, (a Marine Division of VERTEX STANDARD) approved charger. The use of any other charger may cause permanent damage to the battery. r Follow charging instructions provided with the chargers. r Keep the battery contacts clean. Battery Storage Store batteries in a cool place to maximize storage life. Since batteries are subject to self-discharge, avoid high storage temperatures that cause large self-discharge rates. After extended storage, a full recharge is recommended. Battery Recycling DO NOT PLACE USED BATTERIES IN YOUR REGULAR TRASH! LITHIUM-ION BATTERIES MUST BE COLLECTED, RECYCLED OR DISPOSED OF IN AN ENVIRONMENTALLY SOUND MANNER. The incineration, land filling or mixing of nickel-cadmium batteries with the municipal solid waste stream is PROHIBITED BY LAW in most areas. Return batteries to an approved lithium-ion battery recycler. This may be where you purchased the battery. Contact your local waste management officials for other information regarding the environmentally sound collection, recycling and disposal of lithium-ion batteries.

8. CTCSS OPERATION ON THE FRS BANDS

8.1 CTCSS CODE OPERATION

CTCSS stands for Continuous Tone Coded Squelch System; it is a subaudible tone system with 39 selections, labeled CODE01 through CODE39. CTCSS tones are used on FRS channels where there are several stations transmitting on the same frequencies within close proximity to one another. When this occurs, you may hear multiple communications at the same time to the point where it is impossible to clearly receive and understand the transmission of the person calling you. The HX471S allows you to program CTCSS codes for each FRS channel. If multiple signals are transmitted on the channel you selected, you will only hear the transmission of other stations with the same CTCSS tone that was programmed in the HX471S. If the radio does not receive the correct tone on the selected channel, then you will not hear the transmission. 1. Select the FRS channel on which you wish to utilize CTCSS control of the squelch. 2. Press the [MENU] key to enter the Menu Mode. 3. Press the [p] or [q] key to select Menu item (CTCSS). 4. Press the [MENU] key to enable adjustment of this Menu item (CTCSS icon will blink). 5. Press the [p] or [q] key to select the desired CTCSS code number (CODE01 - CODE39). 6. Press the [MENU] key to save the new setting. 7. Press the PTT key to exit from the Menu mode, and activate the CTCSS feature. When CTCSS is programmed the CTCSS code number will appear to the right of the operating channel number. To disable CTCSS operation, select OFF in step 5 above.

Page 34 HX471S

10. OPERATING PRACTICES
10.1 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency may be defined as a threat to life or property. In such instances, be sure the transceiver is on and set to CHANNEL 16. Then use the following procedure: 1. Press the microphone push-to-talk switch and say Mayday, Mayday, Mayday. This is , , (your vessels name). 2. Then repeat once: Mayday, (your vessels name). 3. Now report your position in latitude/longitude, or by giving a true or magnetic bearing (state which) to a well-known landmark such as a navigation aid or geographic feature such as an island or harbor entry. 4. Explain the nature of your distress (sinking, collision, aground, fire, heart attack, life-threatening injury, etc.). 5. State the kind of assistance your desire (pumps, medical aid, etc.). 6. Report the number of persons aboard and condition of any injured. 7. Estimate the present seaworthiness and condition of your vessel. 8. Give your vessels description: length, design (power or sail), color and other distinguishing marks. The total transmission should not exceed 1 minute. 9. End the message by saying OVER. Release the microphone button and listen. 10. If there is no answer, repeat the above procedure. If there is still no response, try another channel.
10.2 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel. However, its most important use is for emergency messages. This channel must be monitored at all times except when actually using another channel. It is monitored by the U.S. and Canadian Coast Guards and by other vessels. Use of channel 16 for hailing must be limited to initial contact only. Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radio traffic, congestion on channel 16 resulting from its use as a hailing channel can be reduced significantly in U.S. waters by using Channel 9 as the initial contact (hailing) channel for non-emergency communications. Here, also, calling time should not exceed 30 seconds but may be repeated 3 times at 2-minute intervals.

HX471S Page 35

Prior to making contact with another vessel, refer to the channel charts in this manual, and select an appropriate channel for communications after initial contact. For example, Channels 68 and 69 of the U.S. VHF Charts are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either channel 16 or 9 for your initial contact. When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to call and then this is followed by the name of your vessel and your Station License (Call Sign). When the other vessel returns your call, immediately request another channel by saying go to, the number of the other channel, and over. Then switch to the new channel. When the new channel is not busy, call the other vessel. After a transmission, say over, and release the microphones push-to-talk (PTT) switch. When all communication with the other vessel is completed, end the last transmission by stating your Call Sign and the word out. Note that it is not necessary to state your Call Sign with each transmission, only at the beginning and end of the contact. Remember to return to Channel 16 when not using another channel. Some radios automatically monitor Channel 16 even when set to other channels or when scanning.
10.3 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. Channel 67 is used for navigational traffic between vessels. By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 20 ([H/L] key) for means to temporarily override the low-power limit on these two channels.

Page 36

10.4 PROHIBITED COMMUNICATIONS
The FCC prohibits the following communications: False distress or emergency messages: Messages to any boat except in emergencies and radio tests; Messages to or from a vessel on land; Transmission while on land; Obscene, indecent, or profane language (potential fine of $10,000).
10.5 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requiring vessels at sea (or other bodies of water) to be notified, the NOAA (National Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone that some VHF radios, including your HX471S, can detect for Weather Alarm purposes (refer to section 6.4.1 NOAA WEATHER ALERT for a discussion of how to use this feature). The 1050 Hz tone, when detected, will produce a loud beep in the speaker of the HX471S, to signal that a Weather Alert Broadcast is being received. In order to test this system, NOAA broadcasts the 1050 Hz tone every Wednesday sometime between 11 AM and 1 PM local time. You may use this opportunity to test your HX471S periodically to confirm that the Weather Alert feature is working, or for training crew members on how to configure the HX471S to receive the NOAA Weather Alerts.
