1. Introduction 1.1. Short Description of Functions The FMD55 possesses the following functions: a) receiver a highly reliable digitally tuned marine receiver with the following features: xfrequency range : 30kHz to 30MHz xreceiving modes : AM, USB, FSK(LSB), CW. xMemory storage : 30 frequencies and modes b) NAVTEX receiver and decoder xFrequencies c) : 490kHz, 518kHz, 4209.
1.2. Operation With its integrated high-contrast, back-lit display and an easy to use keypad, the FMD55 can be operated simply with its user-friendly dialogue. The printing out of system information and decoded messages is carried out by an integrated or external thermal printer using an 80mm wide thermal paper roll. 1.3.

1. OFF Receiver (Operation Switching on for the first time: Control that the unit is properly connected. Switch on by turning the knob clockwise. The display will now show the barograph graphic, date, the time in UTC and NAVTEX STBY on. The unit is now functioning as a NAVTEX decoder on the 518kHz frequency. All incoming messages will be printed out and, an alarm will sound by type A, B and D messages. Changes to the NAVTEX menu can be made as in chapter 5.
2.1. Entering Frequencies x To activate the receiver press the F1<2182> key (should no other input be made, the receiver is tuned to the international emergency frequency 2182 kHz). x Press the key x Enter the frequency in kHz with the numeral keys (correct errors with key). x Control that the input is correct and . x For fine-tuning of the frequency and input of decimal point, use the cursors and . The frequency entered will now be displayed. 2.2.
2.3. Adjusting the Filter The receiver has several filter band widths to optimise the best possible reception. The filter band widths are: 10 kHz, 7 kHz, 4 kHz, 2.2 kHz and 500 Hz Permitted are only those band widths, which cooperate together with the according modes, automatically pre-selected in the decoding mode. Repeated pressing of the key display the following filter band widths for selection: for AM : for CW : for FSK : 4, 7 and 10 kHz basic setting: 7 kHz 2.
a good decoding quality is guaranteed. Interference signals can also lead to a high field strength in display, however the decoding can be strongly influenced by this disturbance. 2.5. Storing Receiver Parameters The FMD55 is equipped with 30 memory stores, so called channels, in which a station frequency can be stored for later retrieval. Retrieval is possible either by using the key or in the timer mode.
3. Decoding of Messages The FMD can receive, decode and reproduce messages in legible characters, when transmitted in Morse, RTTY and SITORNEC codes. Apart from these codes there are many other code types used in radio communication which are ciphered. These types of messages are not for the general public and can therefore not be decoded by the FMD55. Weather, SAR and navigational warnings for shipping are transmitted in codes, which the FMD55 can decipher.
RTTY and SITOR-FEC signals consist of two tones, which alternate uninterruptedly in the rhythm of the information The two tones can be so close together that the depiction in the display merges. This gives the following picture: FSK An interference free reception of a station is not always possible. This is why disturbing signals as well as the required signals are visible on the display.
From the number displayed, the frequency can be calculated as follows: Frequency = 735 + 7.5 x n(Hz).N = number displayed The CF of 1500Hz should correspond to the channel number 102. This means that during MORSE decoding, the number appearing should be between 85 to 120. Should the number differ greatly, then it is possible that the frequency is not properly tuned. The white level for FAX in the SW range should lie between 40 and 60.
Message Transmission Types Transmission Mode A1A - Morse telegraphy with non-damped carrier e.g. Roma, IAR etc. A2A - Morse telegraphy in double side band method A3E - audio radio in double side band e.g. BBC, 4. F1B - FM telex signal from Pinneberg F1B - FM telex signal specially for NAVTEX F1B - FM telex (MSI frequencies e.g. Portishead: 4211 kHz (402) F1C - FM tele-facsimile from Bracknell, Pinneberg etc. F3E - VHF Audio radio from 88 to 108 MHz H3E - AM audio radio, SSB with carrier e.g.
3.2. Decoding Morse Code Signals Having chosen a station broadcasting in Morse code, enter the frequency as in Ch. 2.1. Select the CW mode to receive audible signal, (pitch of tone can be fine tuned with keys and ). Press key . The signal processor will now analyse the Morse signal and convert it into a digital signal. The bottom line of the display will now show CARRIER then SIGNAL and.
3.5 Weather Chart Reception The FMD55 can receive and print out weather charts, (facsimile transmissions in F1C) if they are transmitted according to normal standards. Before printing out a chart, make sure that that you have a reasonably disturbance free reception. For your assistance, apart of the LCD display is reserved to project the incoming signal. The signal is visible within the 855 to 1920 Hz band. Weather transmissions consist of a signal spectrum in shades of white, grey and black.
-SYNC: Correction factor for synchronisation. Basic set-up is +0 -RPM: Choose 60, 90, 120, 240 revs per minute or AUTO (automatic recognition) Generally used: 120 rpm A variance is only necessary when the programme is not exactly synchronised. The projection of a facsimile signal occurs in that the pattern is scanned at a certain speed from the chart lay-out. This speed must coincide with the evaluation of the decoder, so that the signal is printed out correctly.
3.6. Storing Receiver and Decoder Parameters The FMD55 has 30 memory stores called channels and as already described in Ch. 2.5. via the key the following stored parameters can be recalled: x x x x x x Frequency in 10 Hz steps Receiving mode (AM, CW, FSK, USB) Filter adjustments (500 Hz, 2.2, 4, 7, 10 kHz) Decoding mode (MORSE, RTTY, SITOR) Printer selection (P – PRINT) Store message selection (W – WRITE) To allot a memory store number, proceed as in Ch 2.5. 3.7.
3.8. Memory Storage The FMD55 has two separate and independent memory stores for decoded messages. One is for NAVTEX messages (see Chapter 5.) and the other is for MORSE; RTTY and SITOR. The latter has a total capacity of 14000 characters. A message of maximum 3600 characters can be stored in one data record. Should the message be longer, then additional records will be opened. Altogether 100 record with a total capacity of 14000 characters can be set up.
3. Automatic Reception and Decoding The FMD55 has 9 timer stores each containing an ON and OFF time and a store number similar to a video recorder. When programming, for safety reasons, it is advisable to add a minute to the ON time and to the OFF time.
Unless you press it is possible to change the values until they are correct. Having controlled that all data is correct then . By pressing once more you come to a new insertion line and can programme additional times. It is also possible to delete insertions as follows: x Press < NO key CLEAR x Select by means of the numerals <1> to <9> the line to be deleted x Press to delete. By pressing the key twice, the unit returns to the basic standby mode.
4.3. Reading Stored Messages Stored messages can be read out at discretion. However NAVTEX messages are automatically deleted after 72 hours. The memory store has a total capacity of over 16000 characters of which approx. 4500 are reserved for NAVTEX and the rest for MORSE, RTTY and SITOR. When the store is full, the oldest message will be deleted. However this applies to the two different stores separately e.g. a new RTTY message will not replace a NAVTEX message and vice versa.
The display will now show an overall view of the stored messages. By using the cursor keys: Select the message required. x Press the key and the selected message will appear on the LCD x Press and the message can be printed out from the beginning to the end or when stopped by pressing . However it is possible to print out only part of a message e.g. the segment relating to your particular sailing area.
5. NAVTEX Reception and Decoding When the unit is in the basic standby mode it will receive, NAVTEX messages automatically when in reach of a NAVTEX transmission station. However it is important to know that: during reception of other stations or when a stored frequency is being received in the timer function, NAVTEX cannot be received. In order to obtain the best reception of NAVTEX information, it is advisable to set certain system parameters.
5.2. Selection of Filter for NAVTEX Reception From version 3. onwards, the FMD55 has a filter with a centre frequency of 1500 kHz and a band width of approx. 500 Hz in place of the 800 Hz filter. Since NAVTEX is broadcast world-wide with a shift of +/- 85 Hz, this filter can be used for NAVTEX transmission. This is recommendable when in the NAVTEX frequency is disturbed by other stations in your sailing area. Basically for NAVTEX transmissions, the 2.2 kHz has been selected.
By using the keys and you can select the letter required, with the cursor you can change the letter to a capitol and with to a small letter (this means suppressed). An up-to-date (as of Spring 1995) overall view of NAVTEX stations can be found in 5.12. x press the key to return to menu. 5.4. Selecting Type of Message In the menu x press No. <3> to enter mode The type of message is also labelled with the letters A to Z.
4.5. Printer Function If desired, but in general this is not the case, NAVTEX messages can be printed out on receipt. x From the menu press No. <4> to enter mode x Answer with if the message should be printed on receipt or x answer with if the message should be stored for reading later or printing if desired. x Press to return to mode. 4.6. Suppressing Repeated Messages Current NAVTEX messages are repeated every 4 to 6 hours.
5.8. Printing Out of NAVTEX Parameter Status For control purposes all selected parameters can be printed out. This print out will show the frequency, filter, selected messages and stations as well as a list of stored NAVTEX messages. x From the mode press No. <7> x To return to mode press 5.9. Returning to Basic Standby Mode This can be done by pressing the key three times or the keys <8>, <8> and <3> in this sequence. 5.10.

6. Barograph and Storm Alarm 6.1 Description The FMD55 has an integrated precision atmospheric pressure sensor with an amplifier and scoring logic. The graphic range is 950 to 1080 hPa (mbar). The pressure is continually measured and the average evaluation is stored for 24 hours. The current value is displayed numerically in the top right hand corner of the LCD. The average evaluation of the past 21 to 24 hours is shown graphically on the display. The time axis is horizontal.
After checking that all values are correct x Press to accept the new values and x Press to return to the basic stand-by mode. The newly input values appear now in the display as the current measurement. The correction throughout the complete measuring range will be carried out automatically by the micro processor. 6.3.
7. NMEA Printer and Navigation Log 7.1. Printing of NMEA data The FMD55 can be used as an NMEA printer. In this mode NMEA signals are fed via the NMEA 0183 interface unaltered to the integrated or external printer. Please note, that only data, which are defined as NMEA data, can be processed. The unit, which is destined to supply NMEA data (GPS, compass, log etc.), should be connected to the NMEA input of the FMD55. x x x x Press to enter menu Press No.
7.2. Activating log When connected via NMEA 0183 interface to an external GPS, it is possible with the FMD55 to receive, store and print out the NMEA data record "GPS transit specific $ GPRMC", which is practically a complete record of the route. The formula for this data record must read as follows: $GPRMC,111111,A,2222.222,N,33333.333,W,44.555., 666666,77.,E*CS All variants of this $GPRMC data record with the different periods and commas will be recognised and processed.
To control the continual amount of data, two parameters can be selected to define the information according to your personal wish. Parameter 1: time from 1 to 99 minutes You can select, in which time intervals the position should be stored, even when there has been no movement (e.g. at anchor, in berth). If <00> is entered as time parameter, there will be no time-defined entry. This saves data records being stored and printed out, when the vessel is stationary for a longer period of time.
The FMD55 navigation log function will work even when other functions e.g. reception, decoding are in process. Only when an incoming NAVTEX message or a longer decoding is taking place, will the position log be interrupted, however it will commence immediately at the end of the message. At any given time, 50 position data will be stored. After every 50th value, the storage will be printed out automatically.

8.3. Switching On and Setting Timer The timer functions and the automatic return to the basic standby mode as well as the regulation of the back-lit display can be selected. 8.3.1. Switching Timer ON and OFF Sometimes it is necessary to switch the timer off for a short time without losing the stored data. x Press to enter SETUP 1 menu x Press key No. <2> to enter SETUP 2 menu x Press key No. <6> to enter menu The cursor can now be switched either On or OFF by pressing or .
8.3.3. Controlling The LCD Display Lighting The back-lit display normally switches on when the timer mode is automatically activated. This can, in some cases, be distracting at night. For this reason we have installed a function, which can be switched on or off by the user. x x x x Press to enter menu SETUP 1 Press key No. <2> to enter menu Press key No.
All the system parameters will now be printed out in an orderly list. The NAVTEX parameters must be printed out separately in the NAVTEX menu (see Ch. 5.8.) Storing of data: All stored data, such as system parameters, receiver parameters, timer status, stored messages etc. remain stored for at least 3 months, and under optimal conditions up to 12 months. This is possible because of the integrated NiCd battery, which is continually charged when the unit is in operation.

The clip on connection is self-locking, however for safety reasons it is advisable to secure with the pre-set screws. The earth wire (yellow/green) must be screwed to the GROUND connection. The unit was manufactured to operate on a supply voltage of 11V to 15V DC (12V battery). The FMD55 has reverse battery and over voltage protection.
9.5. Record Out- Tape Deck, PC etc. The receiver has a LF output with a drive level for a tape deck (approx. 200mVss) coming out of the REC OUT connection on the reverse of the unit. It is possible here to connect an external tape deck or amplifier. Let the necessary connections be done by an expert. The input of incorrect voltages, or if the signal level is too high, could lead to the destruction of the FMD55. 9.6.
b) internal and external speakers c) external speakers only 9.7. Antenna Connection and Earthing The antenna socket is designed to be fitted to a coaxial cable connection with a BNC plug and impedance of 50:. No provision has been made for the connection of high impedance, unshielded antennæ. The reception quality depends, to a high degree, on the quality of the antenna used. A good antenna guarantees good reception.
9.8. Connecting An Active Antenna The FMD55 is prepared for the supply of an active antenna with 12V DC max. and approx. 300mA. This however not activated on delivery. On the output of the antenna there would be a constant 12 V and on connecting a balun transformer, the power would be short circuited. In order to activate the power supply you must insert the glass fuse supplied (500 map slow-blow).

9.12. Printer paper change The FMD55 has a thermal printer, paper width: 112mm. The diameter of the paper roll must not exceed 45mm and the diameter of the core, no more than 12.5mm. The standard supplied roll has an approximate length of 25 metres and prior to reaching the end, a colour indication will appear, reminding you to change the roll. Changing the roll: 1. Switch the unit off 2. Remove paper roll lid (2 thumb screws). 3. Lift the pressure lever (90° to the casing) 4.
9.13. Connection for RS232 Interface The FMD55 has also an RS232 interface, on which a serial external printer or a p.c. system can be connected for printing out or processing stored data respectively. (See also Ch. 4.5.) Decode or stored data can be transported to a PC for further processing. The output happens analogue to the internal printer print out.
9.15. Remote Control Output (Optional) The FMD55 can be supplied with an output for control from an external relay. The control output works parallel to the backlighting of the display. This switches off automatically in the stand-by mode and, depending on the setting, switches on automatically in the timer mode. 9.16. Adjusting Contrast of LCD Display The contrast of LCDs is generally dependant on temperature fluctuation.
10. Accessories 10.1. 24 V DC/DC Converter The FMD55 can be operated with a DC/DC converter. This offers the following advantages: x input voltage range 9V to 36V x constant output voltage 12.5V This means that the FMD55 can be operated by 12V and 24V batteries. The DC/DC converter has an integrated filter, which suppresses interference from the ship's voltage supply and offers additionally, a galvanic separation between the power supply and the unit. (An advantage for aluminium hulls).
10.2. DC936-12 DC/DC Converter for 9V – 36V DC to 12V DC With the DC/DC converter, DC936-12, it is possible to operate electronic 12V nominal voltage devices with a 24V on board network. Vice versa, with the 936-24,a 24V a unit can be operated with a 12V network. The maximum power consumption of the unit connected can be as high as 30 Watt. By an input voltage from 9V to 36V, the output voltage will be constant. The input and output voltages are galvanically separated.
10.3. Installation of M5X-DC Converter All material for the installation will be supplied. 1. Screw the M3 x 5 mm distance bolts using the spacers into the pre-prepared screw-holes on the reverse of the FMD55. ATTENTION: Do not turn with too much momentum otherwise the threaded stems may break-off 2. Screw on the DC/DC converter with the M3 x 35 mm screws and spacers on to the distance bolts. 3. Attach the connection cable of the converter to the power supply of the FMD55 and screw tight. 4.
10.4. MD-AA Active Antenna for FMD55, 50 and 20 Description: The MD-AA active antenna has been specially developed and tuned for the Fastnet Radio GMDSS Marine Decoder series FMDxxx, but can also be used for any other receiver in the above range. It was mainly designed for the reception of vertically polarised waves in the long, medium and short ranges. Extra value has been placed on a greater spacing interval between the signal and the interference level, rather than reaching a higher output potential.
10.5. MLB Long-wire Balun Transformer for Back-stay The function of the MLB is to match impedance of the high Ohm long-wire stay antenna with the 50( antenna input. The balun is connected to the antenna input with a shielded 50( coaxial cable. This leads the antenna signal to the receiver input but not the noise voltage interference. This results in a vital improvement in the quality of reception.
10.6. F6A Suppression Filter Practically every piece of electrical or electronic equipment on board, which is connected to the vessel's power supply, such as the generator, the battery charger, pumps, refrigerator etc., cause disturbances within the power supply. This could interfere with the function of sensitive electronic equipment, such as a receiver. This filter suppresses a great deal of such disturbance, which may reach the decoder via the power supply.

12.11. Propagation of SW Signals One of the questions raised frequently is to determine which transmissions can be received at what distance from the transmitter. There is a number of factors that affect Short Wave reception and distance vary greatly depending on time of day and year, sun activity and amount of traffic in a particular band. Each band has its own characteristics and as a rule of thumb one could say ‘the higher the frequency, the higher the distance’, at least during day time.
12.12 Antenna Reception onboard Vessels Radio receivers are today, standard equipment on board sea-going vessels. In most cases it is seldom taken into account, that every receiver, no matter how expensive it is, can only function as good as its antenna. What should one take into consideration when choosing an antenna? x The frequency range of the antenna must have the same range as the receiver, at least have the same range that is going to be used.
The lead from the antenna to the receiver must be a nondissapative well shielded coaxial cable with the same impedance as the receiver input. These are usually laid parallel to other (disturbing) cables and near other electrical devices. A badly shielded cable picks up local interference and transmits them to the receiver. The receiver itself should be connected at the shortest possible distance to a grounding sponge. Alternatively an active antenna can be used.
