Yes, very audible here too earlier in IO51do

Quite deep QSB but a good 549 on peaks.

                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). <br>
                <br>
                Yesterday they got on air for the first time, running a
                preliminary test transmission consisting of a 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".<br>
                <br>
                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 coud make it much further.
                The carrier frequency is derived from an OCXO and is
                currently at 1476000.411 Hz.<br>
