Mike you are the "MAN" following your instructions
I downloaded the SDRsharp which applies to RTL & got at last the RTL/USB in
the configuration Window. I clicked on Configure & a window showed up called
RTL settings. I adjusted the RF gain as you suggested up to 40. Now is there
anything else I should indicate in that window please. like RTL AGC, TUNER AGC
ECT ECT
Thank you so much for the clarity of your
instructions.
