Hallo friends!
I am just listening nice signal (dots) on 1475kHz (CW mode).

Hi Alex,
Benoît, and Horst,
thanks for the interest! The transmission is on air
continuously 24/7. At my location 16.8 km away I can of course
hear it well day and night.
Note that there is also an active Iranian station in the same
channel (IRIB Radio Kordestan) but their carrier is ~ 250 Hz
further up.

Markus

Yes, I remember the Donebach activation so I will
take the challenge oh 1476khz. Just blown the dust off
my Präcitronic MV62 :D and waiting for the night.

After the sad demise
of all LW and MW broadcasts in
Germany, a handful of pioneers came up
who are operating legal low-powered
medium wave stations in the context
of a radio museum or for educational
purposes. One of them is Ralph
(DL2NDO, one of the participants in
the legendary Donebach 137 kHz
activation in 2002). He has obtained a
transmitting license for 1476 kHz
(former frequency of Vienna
Bisamberg), built a 3 Watt AM
transmitter, and with the help of a
small team raised a
quarterwave antenna on the Fraunhofer
premises south of Erlangen
(JN59MN21HF).
Yesterday they got on air for the
first time, running a preliminary test
transmission consisting of switched
1000 Hz beeps (one second on, one
second off, audio frequency locked to
the RF carrier). This pattern will
be continued for a few days, before
they will eventually.take over the
audio from the local DAB student radio
"funklust".
The current test pattern is relatively
easy to make out in the noise so it
may be a good chance for some DX
detections. At night we've actually
heard the beeps on Twente SDR and a
couple of German Kiwi-SDRs. But I
guess using narrowband signal
processing techniques, the carrier and
coherent tones could make it much
further. The carrier frequency is
derived from an OCXO and is currently
at 1476000.411 Hz.
Will anyone in the group take the
challenge?
