1. 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.
OFF
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.
ATTENTION !
Frequencies for weather and nautical warnings can be
found in official manuals such as
The Admiralty List of Radio Signals volume 3.
Please note that the publishers and the distributors of
these manuals cannot be held responsible for the
correctness of the frequencies and transmission times.
One must take into account that there is a possibility
that the printed facts are incorrect. Wherever the
contents of different publications contradict, the
master’s decision must be to withhold from
unfavourable statements.
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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 <FREQ> key
x Enter the frequency in kHz with the numeral keys (correct errors
with <CLEAR> key).
x Control that the input is correct and <ENTER>.
x For fine-tuning of the frequency and input of decimal point, use
the cursors <UP> and <DOWN>.
The frequency entered will now be displayed.
2.2. Selecting Reception Mode
The receiver is provided with the following modes:
x AM for the reception of amplitude modulated radio stations
(e.g. BBC 4, Valentia, Athens etc.).
x CW for the reception of A1 signals ( Morse code from IAR,
Roma etc.).
x FSK (frequency shifting key) for RTTY (teletype) and SITOR-
NEC transmissions.
x USB (upper side band) for the reception of single side band
(SSB) modulated signals.
See also chapter 3 – Page 3-1
For the reception of LSB (lower side band) use the FSK
mode.
While in Standby mode, or before the frequency input,
the basic mode is USB.
By pressing the <MODE> key the mode rotates (toggles)
from USB to AM then CW and finally FSK before returning
to USB.
The display will show the selected mode.
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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 co-
operate together with the according modes,
automatically pre-selected in the decoding mode.
Repeated pressing of the <FILTER> key display the
following filter band widths for selection:
for AM : 4, 7 and 10 kHz
basic setting: 7 kHz
for CW : 2.2 kHz and 500 Hz
basic setting: 2.2 kHz
for FSK : 2.2 kHz and 500 Hz
basic setting: 2.2 kHz
The basic setting for USB is 2.2 kHz and cannot be
adjusted. Other filter band widths for SSB are unsuitable.
2.4. Reception of Field Strength
The field strength is displayed as:
>>>__I>>>__
The first five arrows from the left depict the automatic
adjustment control for the signal processor. For
reasonable reception, there should be two to three
arrows. The arrows appearing to the right of the
vertical line depict the field strength reception.
Whether four or five arrows are displayed,
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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
<RECALL> key or in the timer mode.
The following parameters can be stored:
x frequency in 10 Hz steps
x receiving mode (AM, CW, FSK, USB)
x filter adjustment (500 Hz, 2.2, 4, 7, 10 kHz)
Having checked that all the above parameters for the
selected station have been correctly entered then press
the <STORE> key. Now allot a free channel number from
01 to 30 and <ENTER>. The display will now show the
parameters stored on this memory store and with the
selected slot i.e. CHxx.
By pressing the key <YES> you can store the currently
entered parameters and/or overwrite previous entries
stored on this channel
2.6. Recalling Stored Parameters
To retrieve stored receiver parameters press <RECALL>.
e.g. using the numeral keys, enter the desired channel
number (e.g. 01 for the first entry), and press the <ENTRY>
key. The contents of storage will be automatically
transferred to the receiver.
The storage (channel) numbers and the parameters can
also be printed if desired.
Enter SETUP / Menu 2, place cursor on <7 INFO> ( see
chapter 8.1.)
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
3. Decoding of Messages
The FMD can receive, decode and reproduce messages in
legible characters, when transmitted in Morse, RTTY and SITOR-
NEC 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.
The reception signal (LF) is fed to the signal processor where the
usable signal tone is filtered out and converted into digital
information.
The mode of the type of code transmitted by a station, can be
found in corresponding maritime radio manuals. Various
abbreviations are used:
xfor MORSE : CW, A1, A1A, telegraphy
xfor RTTY : F1B, radio teletype,
xfor SITOR : FEC, ARQ, F1B
Before a signal can be decoded, it must be reasonably free of
interference, (i.e. with the least possible noise ratio, no clicking
or crackling, no other disturbing stations in the receiving range).
In the top two lines of the LCD display, a signal spectrum is
depicted to assist in the adjustment.
Morse signals consist of only one tone. By reception of an
undisturbed MORSE signal, the following picture appears on the
display
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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:
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.
* The basic FAX set-up menu appears as follows:
PRINT: NORMAL (BLACK on a WHITE background)
SYNC: +0 (picture will be printed vertically)
RPM: 120 (95% transmissions are at 120rpm)
LEVEL: 1500 (level value for black/white)
STATUS: WAIT (adjusts itself automatically to SYNC on
receiving the start impulse from the
station and through synchronisation
signaltoPRINT).
In all decoding modes, in the top left and right hand
corners of the display header, there are numbers visible.
These are the utility frequencies of the signal processor, as it
is active even in the stand-by mode for decoding of
NAVTEX signals. The number on the left is the lower
frequency and right higher. In the MORSE and FAX modes,
both values are equal. Morse uses only one tone signals and
FAX uses the white picture level value. In RTTY and SITOR
(NAVTEX), two signal tones are displayed. The distance
between corresponds to the frequency shift of the station.
FSK
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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. The two frequencies in RTTY and SITOR
should be roughly symmetrical around 102. Likewise in NAVTEX
they should be symmetrical around 102 but with an additional
distance of about 20 to 26.
3.1. Selecting Mode and Decoding Types
In most manuals, the station mode is depicted as A1A, F1B
etc. The following table is an overlook of the practised
abbreviations for transmission modes in marine radio.
The settings matching for the receiver and decoder can also
be taken from the table.

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 <UP> and <DOWN>). Press key <DECODE>. 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. MORSE,
After a short period the message will appear in legible
characters in the first line of the display. The number in the
top corner is the speed of characters per minute.
By pressing <PRINT> the message can be printed out and
“P” appears on the display. Should the message be stored
for later display and/ or printing, press <WRITE>.and “W”
appears in the display and <ENTER>.
Using the <DISPLAY> key you can interrupt printing as well
as storing.
3.3. Decoding RTTY Signals
Using the same procedure as in MORSE decoding, enter
the frequency chosen and select the mode <FSK>. Press
the <DECODE> key until RTTY appears in display. After a
short period, the signal processor will analyse and the
decoded message will appear on the display along with
CARRIER then SIGNAL. In the case of RTTY the speed of
transmission is shown in Baud e.g. 58 Bd.
Printing and storing of messages is analogue to that of
MORSE.
3.4. Decoding SITOR-FEC Signals
Decoding of SITOR signals is analogue to RTTY via <FSK>
mode. The safety of the transmission of SITOR signals is far
superior to that of RTTY and NAVTEX is also transmitted in
SITOR.
Printing and storing of messages, as by MORSE
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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. With a reasonably clear reception,
you should the following picture on the display:
As a rule it is seldom that you have a perfectly clear
reception, therefore interference will be visible on the
screen as well as the incoming signal. Adjust the receiver
that you hear the best possible reception of a chart signal.
To do this select the FSK mode. The signal can be found
somewhere in a frequency tone range of 1000 to 2000 Hz.
Press the <DECODE> key until FAX appears on the display. A
small menu will now appear on the display allowing you to
adapt the method of decoding to the signal.
-PRINT: NORMAL/ INVERS allocates correctly, the
transmitted signals into BLACK and WHITE
Basic set-up is NORMAL.
The integrated printer cannot pick out the grey values, but
this is unimportant as weather charts consist mainly of black
and white information.
FSK
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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 <RECALL> key the
following stored parameters can be recalled:
x Frequency in 10 Hz steps
x Receiving mode (AM, CW, FSK, USB)
x Filter adjustments (500 Hz, 2.2, 4, 7, 10 kHz)
x Decoding mode (MORSE, RTTY, SITOR)
x Printer selection (P – PRINT)
x Store message selection (W – WRITE)
To allot a memory store number, proceed as in Ch 2.5.
3.7. Recalling Stored Parameters
To retrieve stored receiver parameters press <RECALL>.
Using the numeral keys, enter the desired channel number
(e.g. 01 for the first entry), and press the <ENTRY> key. The
contents of storage will be automatically transferred to the
receiver.
The storage (channel) numbers and the parameters can
also be printed if desired.
Enter SETUP / Menu 2, place cursor on <7 INFO>
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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. When the memory storage is full
while storing, the oldest record will be deleted to make space
for the new one. This means that the latest or most up to date
message will be stored independent of the type of code
(MORSE, RTTY, SITOR). It can happen that a message containing
only a few characters deletes a complete record of 3600
characters thus reducing the capacity to 10400 characters.
Each data record is filed under date and time when the
message ended plus one minute, in the formation:
DDMMhhmm. Further, the data record contains the channel
source and arranges itself under this channel for recalling.
Should the FMD55 be switched off, deliberately or not (e.g.
interruption of supply), then the data record being currently
stored will be deleted because of the incomplete closure.
It can happen that because of heavy disturbance in the power
supply (e.g. engine start with low batteries), the recognition of
the data records has been destroyed or partly destroyed so
that the stored message can only be partly read out or
eventually not at all. When switched on again the unit may not
recognise the record and delete it. Newly decoded messages
will in any case be correctly stored.
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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. Each message is filed under date and time as:
DD MM HH MM (day, month, hour and minute)
x Press the <READ> key call up READ MEMORY menu
x Select type of message to be read with keys <1> to
<4> or <UP> and<DOWN>
The display will now show an overall view of the stored
messages.
By using the cursor keys:
Select the message required.
x Press the <DISPLAY> key and the selected message will
appear on the LCD
x With the use of the keys <UP> and <DOWN> you can turn
the pages. Either by pressing <EXIT> or on reaching the
end of the message you can leave the <READ> mode.
x To return to the basic standby mode, press <EXIT> once
more.
4.4. Printing Out Stored Messages
Stored messages can be printed out as often as required.
The selection of the message is carried out as by reading out
above.
x Press the <READ> key call up READ MEMORY menu
x Select type of message to be read with keys <1> to <4> or

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. Should the print out of the internal printer not function
simultaneously then connect pins 5 and 8 together
The following programmes are suited for data processing:
x Windows Terminal programme
x Norton Commander
x X-Talk for Microstuff
The Baud rate at the interface is 9600 Bd. This means that any
printer with a serial interface with 9600 Bd and FX80 emulation can
be connected. Character length 8 bit, zero parity bit, one stop bit.
Plug assignment - see the next diagram.
9.14 Connection for NMEA Interface
When the FMD55 is to be used as a navigation log or an NMEA
printer, an NMEA unit e.g. GPS, must be connected. The
connections TX+/- of the NMEA ex ternal unit must be connected
with the RX+/- of the FMD55. The TX+/- of the F MD55 are not active
and are only for factory tests.
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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).
Two versions can be supplied:
a) M5X-DC DC/DC converter for FMD55 and FMD55P,
which is fitted directly on the reverse side of the unit
b) DC936-12 DC/DC converter in a separate casing. This
unit can be installed near the unit
Both converters have integrated IN/OUT filters to suppress
noise and ray interference.
www.Busse-Yachtshop.de email: info@busse-yachtshop.de
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. The efficiency is between 75 and 82%, depending on
the fluctuation of load. Special filters have been integrated at
input and output, to suppress noise voltage and radiation
interference and which guarantee interference free operation of
connected devices and from the onboard network. We
recommend that you use shielded cables for input and output.
For this reason, an earth connection has been provided for at
both terminals.

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.
x The output impedance of the antenna must match the input
impedance of the receiver. In other words, the antenna and the
receiver must conform.
x The antenna and the cables leading to the receiver should
transmit the least possible interference to the receiver. This entails
proper grounding of the receiver and the antenna.
Receivers used in the maritime sector are usually 100 kHz to 30 MHz,
i.e. are designed for use in the lowest LW ranges to the highest SW
range. This corresponds to a wave range of approx. 3000 to 10
metres, an extremely vast range. Since the ratio of the length of an
adapted antenna is always in fixed proportion to the wave-length, it
is understandable that a long-wire antenna of a certain length can
only be correctly adapted to one single frequency. Therefore, when
using a long-wire antenna such as an insulated back-stay, it is
necessary to fit between the antenna and the receiver cable, a
suitable adapter. Such adapters exist (e.g. MLB marine long-wire
balun), which solve the problem as adapter with a large frequency
range between the long-wire and the shielded lead cable quite
satisfactorily.
The antenna itself should be as high as possible and installed as far
away as possible from local disturbances.
Practically every electric and electronic piece of equipment
transmit interference signals which should not reach the unit via the
antenna. New equipment with corresponding approvals or CE seals
have been designed and constructed, free of disturbance as far as
is possible. Measurements must betaken to make older units free of
interference.

FMD55 1999 Page 4
The lead from the antenna to the receiver must be a non-
dissapative 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. The input resistor in the
amplifier of an active antenna is very high, therefore it requires a
very short whip. The output resistor of the amplifier is 50: throughout
the whole of the specified frequency range, so that a corresponding
coaxial cable also with 50: which transmits the signal from the
antenna without further loss of adaptation. The difficulty in the
realisation of a good active antenna is that the integrated amplifier
and the impedance transformer are as linear as possible and not
over-modulated by strong signals from nearby transmitting stations
creating self generated interference to the receiver. This is normally
only possible with powerful amplifiers with equally high voltage use
demands finding a good solution between highest possible linearity
and the least amount of draw of current.
Because of the small dimensions, it is easier to find a place for
mounting an active antenna away from disturbing influences. The
lead to the receiver through the shielded coaxial cable is
uncritical. The use of a high quality active antenna will give an
optimum reception.
