1 GENERAL
1.1Introduction
The RT62 and RT64 fixed VHF radios are designed by Simrad and manufactured at our modern factory facility in the UK. The radio is designed to meet or exceed stringent International Regulations including ETS300-162 and EN301-025.
The RT62 and RT64 are robustly constructed using a pressure die cast aluminium case for effective heat dissipation, ensuring maximum transmission performance even after many hours constant use.
Please note that VHF regulations vary from country to country. Simrad sets are approved specifically by the countries in which they are sold and consequently there may be differences in the programming of sets bought in different countries. If using outside the country of purchase, it is vital to check that the set conforms to local regulations before use.
Thank you for choosing Simrad
If you are pleased with your VHF we hope you will be interest­ed in our range of marine electronic equipment, which is man­ufactured to the same high standards as the RT62/64. Please contact your nearest Simrad Agent for a catalogue showing our increasing range of high tech navigational instruments, GPS, autopilots, Radar, Fishfinders and VHF radio sets.

1.2 RT62 and RT64
Both the RT62 and RT64 are available with either a fistmike or telephone handset, and offer the same features. The details in this owner’s manual apply to both models.
The RT64 features a second watchkeeping receiver, allowing it to use the Digital Selective Calling (DSC) system on VHF chan­nel 70. For this the RT64 will need to be linked to the Simrad Class D DSC control unit DSC1400.
NOTE The RT62 is only available for applications that do not require
DSC functions.
This manual describes all operating features available to the RT62 and RT64, including channel scan which is not permitted in certain countries. Therefore this feature may not be avail­able on the set supplied if it was purchased or configured for one of these countries.
1.3 Licensing
NOTE Prior to use check the national licensing requirements for the
operator.
In the UK license applications and queries should be made to -
Ship Radio Licensing Radio Licensing Centre The Post Office PO Box 1495 Bristol BS99 3QS
A set may only be operated by, or under the supervision of a holder of a Certificate of Competence and Authority to Operate. This involves a simple examination and an annual license renewal fee. For details contact -
Royal Yachting Association RYA House Romsey Road Eastleigh Hants, SO5 4YA
Holders of the Restricted Certificate of Competence in Radio­telephony (which covers MF/HF SSB etc), do not need a sepa­rate VHF certificate.
In all other countries, please contact your regional authority for information.

2.2 Operation - Scanning Versions
The radio is switched on using the volume knob. The VHF starts up automatically on channel 16* at maximum power (25w).
*This can be changed - contact Simrad Agent for details
2.2.1 Function (F) / Backlight ( )
NOTE - Secondary functions are only available on scanning versions of
the VHF.
Several of the keys have secondary functions in addition to the main function. These are accessed by pressing F, then the appropriate key within two seconds (do not hold the F key down). When F is pressed, the F legend will appear on the LCD for the two seconds it is active. Pressing another key within this time will access its second function.
Backlighting
The LCD backlighting is switched on and off as a secondary function of the F key. To turn the backlighting on/off press F twice (Fig 2.2). If the F key is held down the second press, the lighting will step through five brightness levels. Release the key when the desired lighting level is reached.

2.2.2 Power (1/25) / Channel Memory (M+)
Although the radio has a maximum transmit power of 25 watts, this is not always necessary if communicating with a sta­tion or vessel that is very close. To reduce power consumption, the transmit power can be reduced to 1 watt. This key operates as a toggle, switching between 1w and 25w (Fig 2.3).
NOTE - Some channels are restricted to 1w transmit power. The radio
is programmed to switch to low power automatically when one of these channels is selected

2.2.3 Dual Watch (D/W) / Channel Inhibit ( ) +
Revert function
Dual Watch enables the radio to scan between the selected channel and the priority channel (normally Ch16). To activate Dual Watch Mode, select the channel and press D/W - the D/W legend will be displayed on the LCD.
NOTE The channel cannot be changed and transmission is inhibited
while in Dual Watch mode. To restore normal operation, either press D/W, 16 or rotate the channel select knob anticlockwise.
Inhibit Function
Since the Scan function locks onto channels where a signal is detected, it will lock onto a channel with a lot of interference noise, or transmitting a continuous carrier wave signal, pre­venting the radio from continuing the scan. The Inhibit func­tion allows channels to be removed from the Scan sweep. Pressing F then D/W ( ) will inhibit the selected channel - indicated by INH appearing on the bottom line of the display (Fig 2.4). Pressing F then D/W ( ) if the channel is already in inhibited will restore it to the Scan - indicated by ENA appear­ing on the bottom line of the display.

REVERT Function
If D/W is pressed when CH16 is selected, the VHF will revert to the previously selected channel.
2.2.4 Triwatch
The Triwatch function is similar to Dual Watch, but this scans between the selected working channel, the User channel and the Priority channel. To set the User channel, refer to section
2.2.10 .
To enter Triwatch mode, press and hold the D/W key for 2 sec­onds. The “D/W” legend and “tRI”will be displayed on the LCD. To exit Triwatch, press the D/W key or turn the channel selector anti clockwise.
2.2.5 Scan (SCN) / Memory Scan (MS)
This function scans through each channel sequentially until a signal is detected above the squelch level set. Once the signal ends or drops below the squelch level, the radio will continue scanning. Press SCN to enter scan mode. The LCD will show SCAN (Fig 2.5).

SCAN
2.2.6 Channel 16 (16)
Will automatically select Channel 16 on High Power when pressed. Any function active (Dual Watch, Scanning etc) will be cancelled.
2.2.7 Squelch (Sq)
This knob is used to adjust the receiver muting threshold (squelch) level. To cut out weaker signals, increase the squelch until the background interference noise disappears. To receive weaker signals, decrease the squelch.
2.2.8 Volume, On/Off (Vol)
The radio is switched on by turning the volume knob clock­wise. To increase the volume, turn the knob further clockwise. To reduce the volume, turn the knob anticlockwise. Turn the knob fully anticlockwise to switch off.

On non-scanning versions of the radio the F key is replaced with a backlighting key . Turning the backlighting on and off requires only a single press of the key. Press and hold
the key when switching the backlight on to step through the five lighting levels and release when the desired lighting level is reached.
2.3.2 User Channel (P)
This function allows a user selectable personal channel to be programmed. Select the channel, then press and hold P. Initially the display will show the previously selected channel, but after 2 seconds the display will show the new channel and USE will appear on the bottom line of the display - the button may now be released. The User channel can now be directly accessed by pressing P.
2.2.10 User Channel (F then 16)
This function allows a user selectable personal channel to be programmed. Select the channel, press F then press and hold
16. Initially the display will show the previously selected user
channel, but after 2 seconds the new user channel will be shown and USE will appear on the bottom line of the display ­the button may now be released.
This channel can now be accessed by pressing F then 16.
2.3 Operation - Non-scanning Versions
In countries where scanning radios are not permitted, the sec­ondary functions listed are not available (Fig 2.7). The primary functions are the same with these exceptions -

2.4Memory Mode
This function is only available on scanning versions of the VHF. It allows the radio to operate using only the channels programmed into the channel memory. Press F then press SCN, holding down for 2 seconds. Rotating the channel select knob will then only select the channels programmed into the memory. To disable this mode and return to normal operation, either switch the radio off and on again, or press 16.
This mode will only be available if there are channels pro­grammed into the memory (see section 2.2.2).
2.5 Second Channel Mode
In countries where it is permitted, holding F/ down while turning the radio on will enable the radio to operate on a sec­ondary set of channels - normally the USA channels (Fig 2.8).
The display will show USA for USA channels, CAN for Canadian channels etc. Channel sets available will vary depending on which country the radio is programmed for use
in. Please enquire with your national licensing authority for details of permitted channel sets.
The radio will revert to normal operation if it is switched off then on again.
2.6 Speaker Mute
On models fitted with a telephone handset, lifting the handset from the cradle will normally mute the front panel loudspeaker automatically.
If required, this function can be disabled by holding down D/W while turning the radio on (Fig 2.9). The loudspeaker will subsequently remain on when the handset is lifted.
As this setting is stored in the radio’s non-volatile memory it will be remembered even if the radio is totally disconnected from the power. To restore speaker muting, hold down D/W again while turning the power on.

3 INSTALLATION
3.1 VHF Installation
The radio should be sited so that engine noise and vibration or other background noise do not make it difficult for the operator to hear.
Although the RT62/RT64 radio is waterproof when flush mounted, it is recommended that it is not installed where it will be exposed to continuous direct sunlight, as this will even­tually damage the LCD display.
As microphones and loudspeakers contain powerful magnets, the radio should not be installed within 1m (3ft 3in) of any compasses, whether magnetic or electronic.
The fins on the back of the case act as a heatsink to dissipate heat generated by the set when in use, which maintains the high efficiency of the radio. The free circulation of air is essen­tial - if mounting the radio in an enclosed space, ensure that the space is vented.
The VHF is supplied with a reversible mounting bracket. This can be used to mount the VHF on the chart table or on an over­head bulkhead (Fig 3.1). The bracket is fixed in place using four No.10x3⁄4 screws (supplied). Before installing, ensure that there is at least 88mm (3.5 in) vertical clearance and 70mm (2.8in) horizontal clearance behind the bracket to allow the radio to fit (Fig 3.2).

The radio is fixed to the bracket using a simple clamp arrange­ment. The peg on the left side of the radio is slotted into the hole in the bracket. The clamp on the right side of the radio can then be slid into the slotted aperture on the bracket and tightened to hold the radio firmly in place (Fig 3.3). The rake angle of the radio can be adjusted by slackening the clamp.

An alternative mounting method is to use the flush mounting kit FMB1000BK (supplied separately). This allows the radio to be neatly installed inside a bulkhead, so that only the fascia of the radio is visible. For more details of this and other acces­sories available, please refer to section 4.1.
3.2 Electrical Installation
The RT62/64 has four electrical connections - the handset/fist­mike socket is on the front panel below the LCD display (Fig
3.4A). The other three are situated on the back of the case - the
antenna socket is on the right (Fig 3.4B), a 3.5mm jack socket for an optional extension speaker on the left (Fig 3.4C), below which is the DC power input via a two core flying lead (Fig
3.4D). An earth stud (Fig 3.4E) is provided to earth the case.

Extension Speaker
The radio requires a 12v DC supply, and is supplied with a power lead which incorporates an in-line 7.5 amp fuse. This lead should be connected to the vessel’s power supply, keep­ing the cable runs as short as possible. Although the radio draws little current when receiving, a heavier current is drawn when transmitting which may result in a voltage drop if very long cable runs are used of inadequate core diameter. If the supplied power lead is not long enough, an extension of up to 3m (10 ft) can be made using at least 2.5mm2 (13AWG) wire.
The red wire is positive and black is negative. If polarity is accidentally reversed, the set is protected but the fuse will blow. Ensure that it is replaced with a fuse of the correct 7.5 amp rating. The radio is designed to be easily removable for

storage or security, so leave an adequate length of cable to ease disconnection. The flying lead from the rear of the radio can then be plugged into the power supply lead. Note that the configuration of the plug prevents incorrect connection.
The antenna is connected to the radio using a standard PL259 type connector as fitted to most marine antennae. If fitting to an existing antenna, check that the contacts are not corroded before connecting, as this will affect the quality of the signal. Ensure that the retaining collar of the antenna plug is securely tightened to prevent accidental disconnection.
The extension speaker socket takes a standard 3.5mm jack plug. The speaker used must have a minimum impedance of 8Ω.
3.3 Antenna Installation Recommendations
The most important factor in the performance of the radio will be the quality and positioning of the antenna. Most recorded problems with VHF radios are related to poor antenna siting, faulty cabling, poor quality cable joints and low voltage supply. Even a VHF as highly advanced as the RT62/RT64 cannot com­pensate for these factors. Therefore, if replacing an existing VHF installation, it is important that these factors are checked when installing the radio.
As the range of VHF signals are governed by line of sight (see section 4.2), the antenna should be placed as high as possible, while remaining clear of any metallic objects that could influ­ence the resonance of the antenna.
The most popular antennae for marine use are 1m (3ft 3in) long. On sail boats these are usually mounted on the mast­head, where the length of the antenna keeps it clear from the navigation lights and windvanes etc. This type of antenna can also be mounted on the cockpit roof or garage of power boats.
Longer whip antennae are recommended for larger boats. These radiate the same total power as smaller antennae, but concentrate it into a narrower beam, which is advantageous on a tall mast at extreme range where concentrating the available power into a narrow horizontal beam becomes more important. However, if the antenna is not vertical when transmitting, the beam will be angled either too high or too low (Fig 3.6). Here the wider beam of the shorter antenna will be more universally effective, although the signal will be weaker (Fig 3.5). Therefore vessels with a large heel angle (small sailboats) would be better choosing a short masthead antenna. Your local

agent should be able to provide specific advice on antenna choice for the vessel it is to be fitted to.
The antenna coaxial cable and any connectors used must be rated at 50. Under no circumstances should standard domes­tic TV cable and connectors be used. Incorrectly rated cabling and connectors could result in power not reaching the antenna, but also power could be reflected back into the radio, damag­ing it in the process.
The quality of any connections and integrity of the cable (i.e no breaks in the sheathing) will directly affect the performance of the radio. Poor soldering or corrosion of the terminals can impair performance. It is recommended that screw or crimp terminal type connectors are not used for any through deck fit­tings - a good quality waterproof solder terminal connector will be less susceptible to poor connection due to corrosion of the contacts.
3.4 Electrical Interference Suppression
Interference generated by the alternator of the engine may occasionally cause problems. The radio has been designed to minimise the effects of outside interference. However, precau­tions should still be taken - route the power supply and anten­na cables away from the engine compartment. The cable run should not be down the same trunking as other cables carrying high current. The antenna cable should also be kept seperate from the radio’s power cable.
Engines with spark ignition - and also some refrigerators ­should be fitted with suppressors. Your local agent should be able to give advice on this, and also supply suppression kits where necessary.

4.2 Transmission Range
Because VHF signals travel in a straight line and are not reflect­ed back off the ionosphere as lower frequency signals are, the range of VHF signals is limited to ‘line of sight’, beyond which the other vessel passes behind the curve of the Earth. Therefore, the range will increase greatly the higher above sea level the antenna is, as Fig 4.1 illustrates (assuming maximum transmission power is used):
Therefore, the typical ship to ship range of a fixed VHF radio such as the RT62/RT64 with a masthead antenna will be approximately 20 Km (12 miles). This will increase as height above sea level increases, or if the other radio user’s antenna is at a greater height - note that the range between the yacht with the antenna mounted on a 9 M (30 Ft) mast and the shore sta­tion increases to 46-53 Km (29-33 Miles).
