You need a wide power loss like EI8JK in my 7th(?) kite experiment.

You need a wide power loss like EI8JK in my 7th(?) kite experiment. Then the QRM is low and you can see the difference :-) Or is it the isolation transformer maybe that causes IM? Maybe it helps to build a portable RX system (Raspi+octo) to test the antenna as it is now in this location. And then, in a second test, build a similar antenna and test it in q quieter location, using the same preamp and transformers... 73, Stefan PS: Here, just completed the 13th of 14 layers of the first of 3 coils for a 970 Hz transformer...
