DIRECTIONSFORUSE
INITIAL SETrINGS
Turn on the receiver on the AF GAIN (12) or on the power supply N1400 or N1401
and turn the AF GAIN (12) to approx. middle position.
Turn the CLARIFIER (15) to the center position, the RF GAIN (13) fully clock-
wise and the AGCSWITCH (14) to position ON. Choose the wanted mode of recep-
tion on the MODESWITCH (II). (For further description of mode filter - and AGC
selection, please examine the paragraphs below).
FREQUENCY CONTROL
The frequency is controlled from the KEYBOARD (I) and the CONTINUOUSTUNING (10)
wheel. The wanted frequency must be entered into the KEYBOARD (1) in kHz and l
is then displayed on the liquid crystal DISPLAY (5). The decimal point is only
to be used when a fractional kHz is wanted. After- entering a frequency the re-
ceiver is blocked and the CONTINUOUSTUNING (10) wheel is disabled.
After keying in a frequency you must press the NOISE GENERATOR(4) and adjust
RF TUNE (7) for maximum reading on the METER (6). For frequencies below 150 kHz
chosen there is no tuning to be done on the RF TUNE (7), just press NOISE GENE-
RATOR(4) to unblock the receiver. ,P
Now the wanted frequency is selected and the receiver front end is tuned. The s
CLARIFIER (15) controls the frequency between the 100 Hz steps selectable. >
For searching over a frequency range the CONTINUOUSTUNING (10) wheel is acti-
vated by pressing the decimal point key on the KEYBOARD (1). When the desired s
frequency is found the CONTINUOUSTUNING (10) wheel can be disabled by pres-
sing the zero key on the KEYBOARD(I).
The CONTINUOUSTUNING (IO) wheel is able to tune the receiver over the full
frequency range 10 kHz to 30 MHz. It is necessary to follow the frequency tu-
ning wheel with the front end tuning on the RF TUNE (7). Each time you pass a
band limit by means of the CONTINUOUSTUNING (10) the receiver blocks. (Band-
limits: 150 kHz, 530 kHz, 1.6 MHz, 4 MHz, 7 MHz, 14 MHz and 30 MHz). To unblock
the receiver again you must press the NOISE GENERATOR(4) and adjust the RF- 0
TUNE (7) for maximum METER (6) reading.
DISTRESS
With the controls set as described under INITIAL SETTINGS above just turn the
MODESWITCH (II) to DISTRESS (2182 kHz.1 position. Now the receiver is ready
for reception on the distress frequency, mode selection (AM) and front end tu-
ning is automatically done in the receiver.
SSB TELEPHONY
For normal telephony purpose turn the MODESWITCH (II) to A3J (SSB) position.
Now SSB reception of normal upper sideband is established.
For SSB telephony purpose the preferable AGC (14) position is ON.

DIRECTIONS FOR USE cont.:
It is possible by means of the RF GAIN (13) to control the attack level for the
AGCsystem in such a way that signals below a certain level not attacks the AGC
system.
In noisy environments it can be advantageous to switch OFF the AGC (14) and con-
trol the gain by the RF GAIN (13) to avoid that noise impulses activates the AGC
circuit.
Another possibility for gain regulation under strong repetitive noise impulses
is to switch the AGC (14) to the TELEX position and turn the RF GAIN (13) fully
clockwise.
The AGC system now regulates the amplification down immediately and thus pre-
vents the noise impulse to be heard in the loudspeaker. When the noise impulse
disappears again the amplification increases rapidly. This fast AGCsystem sup-
presses effectively noise impulses, but for SSB purpose it furthermore introdu-
ces some distortion because of the missing hang time in this position. For that
reason it is only advantageous to use the TELEX AGC system when your environ-
ments is so noisy that the ON pos. is unusable.
GENERAL BROADCASTING
With the controls set as described under INITIAL SETTINGS above, turn the MODE
SWITCH (11) to A3H (AM) position. Now you are ready to key in a wanted frequ-
ency or search by means of the CONTINUOUSTUNING (IO) as described under FRE-
QUENCYCONTROL.
TELEX IN SSB MODE
For telex reception the receiver is operating as described under SSB TELEPHONY.
Because of the nature of the telex signal (it contains no envelope modulation)
is the most advantageous AGC (14) choice the TELEX one. The extremely good
noise performance of this AGCis fully utilized because no distortion can be
introduced.
Special attention must be paid to the frequency selected. The telex service fre-
quencies listed by the authorities are assigned frequency. For that reason you
must set the frequency either 1700 Hz or 1500 Hz below the assigned frequency,
depending upon the telex equipment used.
TELEX IN AUX, MODE IF TELEX FILTER IS FISTED
As in the TELEX IN SSB MODEexcept that the MODESWITCH (11) is set to posi-
tion Al (CW) and the FILTER SWITCH (9) to position AUX.
WDLILATED TELEGRAPH
With the controls set as described under INITIAL SETTINGS above, turn the MODE
SWITCH (11) to position A2 (MCW)and the FILTER SWITCH (9) to INTERMEDIATE.
The AGCsystem now chosen is the SSB one, and you must set the AGC (14) to the
most suitable position (ON or TELEX) after the present noise conditions.
TELEGRAPHY
With the controls set as described under INITIAL SETTINGS above, turn the MODE
SWITCH (11) to Al (CW) position and turn the FILTER SWITCH (9) to suitable band-
width. Now the receiver is ready for telegraphy reception and the BFO (8) is ope-
rational and can be tuned to a desirable beat note. For the same reasons as de-
scribed in the telex paragraph the most advantageous AGC (14) choice is the ON one.

PRINCIPLEOF OPERATION
Jj
RECEIVER Rllzo
The SAILOR R1120 is a fully synthesized double superhetereodyne receiver
with 10.6085 or 16.6085 MHz 1st IF and 600 kHz 2nd IF.
The signal from the aerial is led through the BANDFILTER UNIT to the
FIRST MIXER, where the aerial signal is mixed with the fLO1 signal ha-
ving frequency resolution of 1 kHz, and thus giving a 1st IF frequency
range from 10.6081 MHz to 10.6090 MHz or 16.6081 MHz to 16.6090 MHz.
9

PRINCIPLE OF OPERATIONcont.:
The signal is then led through a double monolitic crystal filter to the
SECONDMIXER, where the signal is mixed with the fL02 signal having con-
tinuous tuning in the frequency range from 10.00795 MHz to 10.00915 MHz
or 16.00795 MHz to 16.00915 MHz, and thus giving a 2nd IF frequency of
600 kHz.
The 16.6085 MHz 1st IF is selected in the frequency range 0.0100 MHz to
13.9999 MHz and 10.6085 MHz in the range 14.0000 MHz to 29.9999 MHz.
The protluced 2nd IF signal is led through one of the five filters avail-
able on the IF FILTER UNIT. The switching takes place electronically by
means of the MODEand/or the FILTER SWITCH.
The signal is then passed on to the IF2 AMPLIFIER and DETECTOR.The IF
amplifier consists of 3 AGCcontrolled amplifier stages. The detector for
both AM and SSB reception is an envelope detector, and in the SSB and CW
mode the carrier is reinjected in such a way that the incoming signal is
converted to an A3H signal.
l
The reinjected carrier in SSB mode is 600 kHz derived from the 10 MHz re-
ference oscillator, and in CWmode the carrier signal from the beat fre-
quency oscillator BFO is used. This frequency can be varied between 599.5
kHz and 601.8 kHz.
The AGCDETECTORAND AMPLIFIER consists of the AM AGC system and the hang
AGCsystem.
The audio frequency signal is fed from the detector to the AF FILTER AND
AMPLIFIER, consisting of an audio filter, a preamplifier and an output
power amplifier, which delivers signal to the fixed AF output (0 dBm),
the headphones and the speakers.
FREQUENCYGENERATION
The necessary frequencies are generated by two frequency synthesizers accor-
ding to the phase locked principle.
Local oscillator signal fLO, to FIRST MIXER is generated in the phase locked
loop 1 and has a resolution of 1 kHz.
Local oscillator signal fL02 to SECONDMIXER is generated in the phase locked
loop 2 and has a resolution of 100 Hz, and continuous tuning over the 100 Hz
steps by means of the CLARIFIER.
LOOP 1
The voltage controlled oscillator (VCO) generates the necessary local oscilla-
tor signal to FIRST MIXER in twelve 2 MHz bands selected by the BANDCONTROL
UNIT. Inside each 2 MHz band the VCOfrequency fLOl is controlled by a DC con-
trolled voltage derived from the PHASEDETECTORand filtered out in the LOOP 1
FILTER.
10

PRINCIPLE OF OPERATIONcont.:
The PHASEDETECTORcompares two signals, a variable frequency f
rence f+equency fR,. The reference frequency fR1 is the IO MHz
divided down to 1 kHz.
The variable frequency fV1 is generated from the VCO frequency fL0, in the
following way:
In the LOOP 1 MIXER the counter frequency fTl is produced as the difference be-
tween the VCO frequency fLO, and the frequency fHARM which is a multiple of 2
MHz derived from the 10 MHz TCXO.
fT1 = fLOl - fHARM = fLOl - (m x 2 MHz)
q N1 x 1 kHz
For each 2 MHz band a new fLOl and fHARM is selected by the BANDCONTROLUNIT,
and it always results in a 2 MHz variation of the frequency fTl to PROGRAMMABLE
DIVIDER.
The frequency fT1 is divided down by a dividing figure NJ in the PROGRAMMABLE
DIVIDER to the variable frequency fV,.
fVl z fTl/Nl = 1 kHz
The working principle in a phase locked loop is as follows:
A frequency error between the variable frequency fV1 and the reference fre-
quency fRl will via the PHASEDETECTORand the LOOP 1 FILTER cause a DC
control voltage controlling the VCOfrequency and consequently the variable
frequency fV1 so that fV1 follows the reference frequency fR1 in frequency.
fR1 =
fVl
q 1 kHz
The VCO frequency fL0, is now phase locked on a fixed frequency to the re-
ference frequency fRJ and has therefore the same accuracy as this.
Changing of the VCO frequency fLO1 by 1 kHz is carried out by changing the
dividing figure N1 in the PROGRAMMABLEDIVIDER by one.
fLol q fHARM + (N, X 1 kHz)
Principle of programming:
The PROGRAMMABLEDIVIDER contains a counter circuit counting down from a
start figure 2000 + PI and stops at the stop figure St. Each time the coun-
ter reaches the stop figure S,, a pulse (fV1) is fed to the PHASEDETEC-
TOR, and the counter starts counting down again from the start figure 2000 +
PI. Division of fTl by N1 is now achieved.
l

N, = 2000 + P1 - S1

PRINCIPLE OF OPERATIONcont.:
The BANDCONTROLunit selects the correct VCO- and HARMONICFILTER range.
Inside each 2 MHz band the programmable figure PI, is encoded from the
KEY BOARDCONTROLunit in BCD code representing the frequency within the
2 MHz band.

Output frequency from Loop 1:
fLOl = m x 2 MHz + (PI + 2069) x 1 kHz; 7rmd18
l
LOOP2
The voltage controlled crystal oscillator (VCXO) generates the necessary
local oscillator signal to SECONDMIXER. The VCXOis in the Loop 2 system
phase locked to the internal 10 MHz reference frequency.
The phase locked loop principle is the same as for the Loop 1 system. The
only difference is that there are two mixers in the feed-back path, where
the one injection signal is a fixed 10 MHz 0~ 16 MHz signal and the other
one fCL is the CLARIFIER signal.
The CLARIFIER has a frequency variation of 2150 Hz which results in a
2150 Hz variation of the VCXOfrequency fLO2.
Principle of programming:
The frequency shift in Loop 2 is controlled from the 0.1 kHz code from the
KEY BOARDCONTROLUNIT.
The PROGRAMWBLEDIVIDER counts up from the start figure P2 to the stop
figure S2.
The 0.1 kHz code controls the start figure P2 to the PROGRAMMABLEDIVIDER.
Start figure: OhP2rz9
Stop figure: s2 q 20
Dividing figure: N2 = S2 - P2 q 20 - P2
