Hi Phil, >If the IF output of the R9000 is 10.7 MHz and you have SDRMAX's "Displayed >Frequency Control" offset set to 62.5 MHz then 10.7 + 62.5 = 73.2 MHz. Set the >"Displayed Frequency Control" offset back to 0 MHz and your display will be >10.7 >MHz which is the IF you are feeding into the QS1R.
I'm sorry I'm so frustrating but this paragraph alone does not work on my unit. I assume I am getting 10.7 MHz out of the IF and I am tuned to 1420. I open the DFE and put in 62.5 and hit enter but 73.5 does not show. I get 374,999,540,0. Then I set the offset back to 0 and I get 312,500,000,0 and the panorama shows 314 to 330 approximately. My Rx=0 and res 1 Hz. This not working. Do you suspect a defective unit? I don't blame you if you are p**sed off. Maybe I should go back to SDR-IQ and sell this QS1R? --- In [email protected], "Phil N8VB" <p.coving...@...> wrote: > > > > > This question from this poster has been answered multiple times now on the > QS1R group.
