AEG E800/2
Thanks to a fellow
ham radio operator here's the first
report on the AEG
E800/2 on the internet.
He gave me his
E800/2 for testing for
2 weeks. At
this point, many thanks to
Paul, HB9MFD.
Virtually nothing is
known about this
professional receiver. According to
my
knowledge it was
offered on Ebay only once.
And that's it!
The E800/2 is based on
the well
known and sought after E1800
receiver series. So why an E800/2?
For some simple monitoring tasks,
such as e.g.
the interception
of voice
communications, the
E1800 was
simply too expensive. Not every
agency was
ready to spend around
50'000DM for such a device in those
days. Considering that
a monitoring site was using
several, perhaps
dozens of
these receivers, one can imagine the tremendous cost it must have caused.
That was the reason why the E800/2
was developed.
A slimmed-down version of the E1800, so to speak.
The E800/2
cost around 32'000DM. It
is not constructed
in a modular
fashion, so it weighs
only about half of the
E1800/3. It
consists of only
two large circuit
boards, a
linear power supply, and a
control unit which is bolted to the front panel.
This corresponds to
the conventional construction
of a amateur
radio receiver. Also
some electronic
downgrades were
performed
which were not important
for use. For
example a slower
synthesizer because
the E800/2
was not used
for direction finding.
Also the number of control elements
was reduced.
The RF gain
control and the BFO control
have been
omitted. The control
of these functions is taken
over by a "magnetic snap"
VFO tuning knob. All this
could make you believe
that the savings lead to a reduced reception performance.
But far from it! The reception
performance is nearly identical to the E1800/3!
The large
signal
handling capability still had
to be very good because
the E800/2
was used in large
transmitting /
receiving stations.
Here the
key facts and figures: Tuning range:
10kHz
- 30MHz Tuning steps:
Tuning rate
depends on the
selected bandwidth
Position
slow:
1/2 turn
corresponds to a
change of frequency
approximately equal to the
set IF
bandwidth
Position fast:
1/2 turn
corresponds to a
change of frequency
approximately equal to 10x
of the set IF
bandwidth
Smallest tuning step:
10Hz Modes: AM,
USB,
LSB, CW, RTTY

The
E800/2 is very
easy to use. Actually, almost
the same as
the E1800/3. Like its big
brother, the
E800/2 has no
tools on board to fight noise. The
reception quality is nearly the
same as for the
E1800/3 System. On usual
SWL antennas the
E800/2 works
without any problems.
Using manual
gain control will be
of advantage. It will
reduce noise
and make listening
more enjoyable. Used like that
the E800/2 delivers
great audio!
One point should be
mentioned here.
The AGC
of the E800/2 is more suitable for voice reception
than the
E1800/3! It is
not as fast as
the E1800/3.
All in all a great receiver!
The E800/2
is
more suitable for the
SWL compared to the
E1800/3. But
only in one regard!
The repairability! It
is built like an amateur
radio receiver
and much easier to repair.
Unfortunately,
the problem is
the availability of
parts. Should
the receiver fail, you will have similar problems
as with
theE1800/3.
My tip:
professional receivers are
for professionals
:-)
