Let's see if we can keep the ball rolling.Not sure if everyone knew about these LF stations that transmit almost continuously in the LF band. One is the German weather station DDH-47 on 147.300 kHz. It does not transmit 24/7. And then there are 3 different EFR teleswitch transmitters that are used to turn on/off power to lights and other public utilities in Hungary and Germany. As far as I can tell they transmit 24/7. One station is HGA-32 on 135.6 kHz, another is DCF-39 on 139 kHz, and finally is DCF-49 on 129.1 kHz. All of them are a lot of fun to watch and decode using free and easy to use software.
Here are two videos I made showing some of their digital data being received and decoded. Hope you like. 73 Gedas W8BYA
