biteXpress 15896 kHz

Hi,

The 15-16 MHz is ideal for DRM transmissions from central and southern Europe to be received at my location right now.
I managed to receive the 100 W Tx in Erlangen Germany tonight. There was two sets of different labels: 'audio service' , 'bit eXpress' , and also bit eXpress News.
No audio, just 6 dB SNR.

Hi!

Just noticed yesterday that bit eXpress 15896 kHz was strong enough to decode here in Helsinki. Maximum SNR was 24 dB for a short time. The audio quality was high and all channels available.

1. bit eXpress AAC(24 kHz)+SBR P-Stereo (27.28 kbps)
2. bit eXpress News AAC(24kHz)+SBR P-Stereo (27.28 kbps)
3. bit visuAlity Data Services: MOT Slideshow (4.08 kbps)
4. Journaline Data Service: News Service Journaline (4.08 kbps)

Channels 1 and 2 was sending the same program.

DRM has really many extra values referring AM-broadcasts. Reading news and looking pictures while listening music is fine.

Hi,

Amazingly good result today from bitExpress, with a SNR peaking at 22 dB!
A lot of text messages besides good stereo signal:

According to their web page (http://www.bitexpress.de/technik/frequenz) the power is 55 W into a 5/8 lambda antenna.

Hi,
I did not expect to receive this small powered Tx and out of the target area. But I did, of course with a lot of dropouts, but when the audio was on, the stereo sound was very pleasant. I think that the 19 meter band is favour to DRM TXs. Look at the log.

Hi,

Not as good as in November, but the signal from biteXpress was received in stereo. I never managed to get any result from the second service; Multimedia.
