1509s Interferer appears to be about 5 KHZ predominantly E Channel ... something nearby. should be easily defined. Meanwhile suggest he turn down E field Gains.

I am still searching to find the reason.
My transmitting antenna is 50m away from my blitzortung station.
With 100Watt PEP power I have no problems.

Maybe the shown signal is a VLF transmitted morse or digital signal.

Additional investigations show that my Power over Ethernet injection device (nearby under my transmitting antenna) is getting unstable in the 48V regulation while I am transmitting. It seems that the PoE extracting device at the controller side can't stabilize the 5 Volt while 48Volt is unstable causing fluctuations at the Analog Digital Converter unit. I will try to verify this with dedicated measurements. I write this as if this is true other similar signals of stations can be investigated to unstable power supply reason.
