Short Description Constantly transmitting Signal. Switches frequency. 465.97 MHzMegaHertz (MHz) 10^6 Hz, 466.23 MHzMegaHertz (MHz) 10^6 Hz and 466.075 MHzMegaHertz (MHz) 10^6 Hz

Audio Sample

Received near city centre Hannover, Germany with a NooElec NeSDR SMArt with a diy antenna. I used SDR#. This signal is constantly transmitting (at least today) but switches frequency. From 465.97 MHzMegaHertz (MHz) 10^6 Hz for about 28 seconds (you can hear that in the soundfile), to 466.23 MHzMegaHertz (MHz) 10^6 Hz for 28 seconds and at last to 466.075 MHzMegaHertz (MHz) 10^6 Hz for 28 seconds as well. After that it repeats in the same order. I searched for this kind of signal on sigidwiki for half an hour without any luck.

Any ideas?



22.01.2019 It´s POCSAG https://www.sigidwiki.com/wiki/POCSAG

A few years ago i found the same transmissions and posted them here. (Merged with the POCSAG Page)

I tried to decode them and found out that it´s "E*Cityruf" https://www.emessage.de

A Pagersystem for Germany that you can receive basically everywhere in Germany.
