70MHz 50MHz 50MHz RFI picture of SolarEdge SE8K PVC at 50m distance Finally i found the noise source that was frustrating weak signal reception here at the high frequencies. I took again my IC706 with a small motor bike battery to investigate better this time. I had to improvise with the rig I have the old but fb IC706 a bit heavy but good. I really need a selective broad spectrum receiver that covers the whole HAM radio spectrum. The SDR RTL USB 40-1800MHz receiver is a thing that could do that job. But this RTL stick is only working stable / reliable with W10 I could not use it with W7 and it is missing the short wave bands below 40MHz The red Pitaya SDR could be the best device a reason more the purchase this miracle device.. The above 50MHz spectral QRM source is my neighbors SOLAREDGE SE8K at 50 distance. My normal noise floor is below -60dB but since about a year my low noise environment is
