Bottom post or top post for this group? I will post this reponse to top and change to bottom if that is the groups preference.
Thank you for such a quick response Alberto, I am home now and can check settings and see what they do. One problem I was seeing "LO" as "Low" rather than "Local Oscilator" - now I understand the use. AFter much fooling around, switching between 4 different programs - I FINALY figured to swap the I & Q and now it is correct freq read out. I noted as I turned the VFO upscale, the CW signal on Winrad would go down scale..... Hmmmm, decided to swap I&Q, then it seems to read freq where it should with the LO set to 7.056 as it should Alberto, I thank you again for providing a GREAT program - I have been comparing to PowerSDR and darn it, I do think I hear a LOT more with Winrad than PowerSDR - just seems to pull the signals out better. 73 de Ken H> K9FV > Hello Ken, > > first of all, thanks for your nice words about Winrad, they are > really appreciated. > > About the frequency displayed, Winrad relies entirely (when used with > a Softrock) on the correctness of the crystal used as LO on that > board, and on the correctness of the sampling rate of the sound card. > If they are both exact, so is Winrad.
