RE: [Discuss-gnuradio] IF Frequency of WBX board

Hello Josh,

Thank you very much for the reply. It seems to me that these functions are generic and not WBX specific. If I understood you correctly, WBX board does not have a fixed IF frequency. I had some experience with other SDR platforms where their RF boards have fixed IF frequencies at 30 MHz (Super-heterodyne receiver). This is not the case for WBX board?

Kind regards,
Yahia Tachwali

The IF frequency is generally the error in tuning between the target
center frequency and the actual center frequency. You can also manually
control the tuning, so the IF frequency could be anywhere between +/- 40
MHz (for example).
