SOLAR EDGE 8k on air...

Image
50MHz  antenna direction SOLAR EDGE 8k the fun is gone  with 20dB  extra noise 12 hours a day The SOLAR EDGE  SE8k at 50m distance  contaminates the whole  HF and VHF spectrum  1 to 146 MHz  !! with noise and 200kHz separated digi trash this noise is maximum at the display opening in the case   it is generated by the EMC disaster CPU  The unit is still under guaranty so i can not open it to see what is wrong The provided HF filtering in the PV power lines did not help  since the  RFI is not on these lines  Wire mesh over the display area weakened the noise just a tiny bit The single phase Solar Edge PV converter with optimizer seems to be clean So what is wrong with the SE8k ??


Antenna at minimum noise

474.2 kHz  no sign anymore of WD2XSH/17   last time seen TA decodes was 25 March  Might be that transmissions are stopped fttb  the Aurora did kill all DX on the low bands
