Frequency display and LO

Postby G0IUW » Fri Sep 30, 2016 2:57 pm

Hi Everyone...

As a Forum and SDRuno newbie (I have used a Flex 5000A for a couple of years)..one thing I cant seem to get my head around (there will doubtless be many others! ) is that after a while of tuning around and band swapping, the LO frequency as displayed in SP1 is often way different from the tuned frequency set in RX1.
Should they be the same? have I set something wrong? should I try to equalise them?

The LO frequency shows what the RSP is tuned to. The other frequency is the VFO (represented by the red line in the SP1 window) and that can be anything within the specified bandwidth of the LO frequency.

Best regards,

Ah... OK thank you, that is clearer now.
