Hi group, I'm using an Elektor SDR. I wonder if somebody observes a really good mirror frequency rejection?
I observe almost always nearly the same display at +f an -f from center? I've checked all the obvious things. Soundcard works in stereo. Channel separation is ok. LPF of the soundcard is working. The Elektor board was purchased ready built so should be ok as well. ?? Best regards, Walter p.s. I'm down to the VLF. But SW isn't any better ...
