My main receiver is a modified AirSpy HF+ (LW enhancement) and I've noticed something that puzzles me.
When I launch Console V3 and then I open my HF+ without switching on the Miniwhip amplifier, I get signals (just stronger ones) with a very low bed noise level. Then I switch the amplifier on and the rest of the signals on the MW band appears with a reasonable low noise level as I live in a quiet rural area.
But when I first switch the MiniWhip amplifier on and then I launch the software and then open the HF+ receiver, the signals are there, but the bed noise level is higher by, saying... 15 dB, so the S/N is worst than before.
Why is this happening? Supposedly the noise must be the same in the system, but it is not!
