Thanks to Elektor Electronics and Burkhard kainka, my SDR functions well
I would also like to inform that I made a single sided PCB as the components are less. If I am allowed I would love to share it on the forum.
I have a request to MR Kainka.
whether a software with SDR2 (1KHz steps ) is possible for preselektor ver2 please?
However a picture is here, please don't be taken back by seeing a gang capacitor as my 1SV149 have not yet arrived.
