SWR Kaiserslautern 1485 kHz, 300 W

Hi,

using the tuned loop antenna, I was able to receive the DRM test transmission on 1485 kHz from Kaiserslautern last night. Here is a screenshot. TX distance, calculated using the coordinates of the nearby AFN transmitter, was approximately 317 kms.
Unfortunately, field strength and SNR were much too low for audio, but the station label and the labels of various other services were displayed, see screenshot. 1485 kHz is a low power channel that is used by many stations all over Europe, so the channel cannot be expected to be clear.

On 7th Oct early in the evening 18h00 conditions must have been good for a path to north London I managed to achieve service descriptions for Das Ding. Has any body ever decoded audio in UK?

1485kHz SWR Das Ding

hello everyone

A few days ago I got a mixer 455 to 12 kHz. I took the 455kHz from my AOR 7030 and used it.
Yesterday evening I listened to SWR Das Ding.And strangely I could not "hear "it on the ALA 1530 whatever the direction or on an other magnetic loop. But it was fair on a T2FD only 17 meters long.

I think this strange , but maybe there is a logical explanation.

Th e reason I use "hear"is that the SWr came never over 10 dB so the station ID no problem but the audio was never heard.

Greeting Han

My location is eastern part netherlands 51 55 N 0550 E

Edit: Hi Han, moved your post to this thread (Simone)

Unfortunately I hear french and spanish a.m. on that frequency coming from the same direction at my location, so cannot reduce the interference with the loop antenna.

Good visible signal sometimes, but just a little too much interference from the same direction.

From information available elsewhere, it is highly likely that this is not only Kaiserslautern but also Wolfsheim perhaps transmitting with a bit more power.
Signal strength on this frequency has increased quite a bit here in Munich during the last few days but interference levels are still high.

The signal comes not only from Kaiserslautern. It seems that SWR has started also DRM transmissions from Wolfsheim on 1485khz, because the signal strenght improved a lot here in Frankfurt. It is now at daytime at S9+5dB, but the SNR is quite low. I think that they still have some technical problems.
