2. FM area
The FM input signal travels from the antenna via the AM-FM switch to the input of the
transformer Tr. 101. The input circuit formed with the secondary side of this
transformer is strongly attenuated and by the low input impedance of the pre-stage
transistor T 101 tuned to mid-band. In the collector branch of the transistor Lie

voltage drop across R 102 (150 Ω) preloaded Damping diode Di 101, which prevents an voltage drop across R 102 (150 Ω) preloaded Damping diode Di 101, which prevents an voltage drop across R 102 (150 Ω) preloaded Damping diode Di 101, which prevents an
overdriving the mixing stage for large input signals comparable.
via the capacitor C 109 (4 pF), the amplified input signal reaches the emitter of the
self-oscillating mixer stage 102. The T
inductively tunable oscillator circuit loading
protrudes from the variometer L 102 and the circuit capacitance, Ge forms the trimmer
C 114 (3/10 pF) and the series connection of C 115 (18 pF) and C 116 (39 pF). The
feed- back a part of the oscillating voltage is done via C 113 (4 pF) to the emitter.
While the oscillator circuit to a capacitive Abgri the collector of the mixing stage ff is

for the oscillator frequency affects the IF
Coil as a high impedance choke through which the collector receives the operating
voltage. For the IF frequency, however, the relatively low-variometer coil L 102 is
parallel to the capacitors C 115 (18 pF) and C 116 (39 pF) to ground. The input and
output capacities,
in particular the
Oscillator and mixer transistor, are very dependent on the collector emitter voltage tor.
Therefore, the operating voltage by means of zener diode Di 208 was stabilized, the Di

3. NF gain
From the volume control the NF-voltage across C 301 (0.1 uF) reaches the input of the
transistor T 301. The high input resistance itself of this stage will now be greatly
reduced by the necessary basic divider. For this reason, it must How-through feedback

demodulation stages is very low. In addition, the high input resistance for the
connectivity of a plate-tenspielers or tape recorder is desired.
The emitter resistor R 304 serving as an external resistance of the precursor and acts
at the same temperature-stabilizing effect. The second NF-T transistor 302 amplifies
the low-frequency signal in the emitter circuit. In this stage, the resistance R 309

Mechanical design and function
The device EUROPA TR is 2-part, it consists of a receiver section (RF-IF part) and the
NF-part. The latter is screwed on in the normal fal l pivotally mounted on the receiver
part (fi gure 1 + 2). The LF section to be disposed of by the receiver part.
The tuning is done via the function keys of the printing unit and is possible in two
ways:
1. manual tuning,
2. The push-button voting.
Operation of the hand vote:
(For this purpose, see FIG. 7, 8 a, 8 b, 9, 10)
The hand drive shaft is provided with a screw WEL surface engages the hub located
on the drive wheel. A leaf spring presses the hand drive shaft against the thrust
bearing and in the drive gear, thus causing a play-free engagement of the tooth flanks.
The hub is ferrous ben the already mentioned driving wheel also riveted a frustoconical
clutch housing. The counterpart of the coupling is a triangular shaped clutch plate
screwed on the drive stud of the rocker
is.
The compound of the clutch is accomplished by a spring pressure. Upon rotation of the
hand drive shaft, the drive wheel wi rd moved, which pivots the rocker about its axis.

variometer coils with clockwise rotation they move in the opposite direction. In this
way, wi variable adjustment to the individual transmitters around causes.
Operation of the pushbuttons vote:
(For this, see Figures 7, 8 a, 8 b, 9, 10). The push buttons
have two functions:
1. Switching to different wavelength ranges (LW, MW, SW, FM) and
2. Determination of preferred stations for any repetition.
The station selection using the pushbutton following happens so:
First, wi the desired band around by actuating the corresponding push-button set. To

Notes for mechanical adjustment and repair work
1. Remove lid
The lids are not screwed and can be opened with a screwdriver. The aim is

the rear side between the locking spring and the upper edge of the screw. By a
simultaneous rotation of the screwdriver, the DEK takes off angle. The lid
is then easily by further waste

2. Setting the hand drive shaft (Abstimmachse)

b) with a further screw, lever-like intermediate the anvil and the base rule used,

Then loosen slightly while tightening the mounting screw first default. Check
the setting.

pull the lamp shade easily on the top edge forward.
c) The tension spring Unhook the right on the window screen. Glare screen lifting the
right and to the spacer bolt as the fulcrum pivot upward. Here, the light shade
hanging down out of the glare screen support and is now with the simultaneous
lifting of the spacer bolts to the right removable.
d) The scales lamp is then free for replacement and is increasing by pushing against
the springy contact challenges.
8. Replace the print button
a) t Mi matching screwdriver on the underside of the push-button through the cutout,
the narrow spring tongue with a rotary motion to the shift rod and press at the
same time pull the push button to the front.
b) The mounting of the push button is done by simply plugging up to the stop, while the
