Have had my Afedri sdr for about five days. Some minor issues, early on, but all is running well using HDsdr. Is there somewhere I can find a users guide to Hdsdr? I mean simple things like how to tune lsb/usb so I can understand it? Should you use AGC or AFC or both, for weak stations? Or do I simply need to find a basic guide to tuning regular shortwave receivers? I am mostly a scanner guy and shortwave confuses me.
