Frequency Shift #14

Closed Kris1958 closed 3 months ago

Kris1958 commented 3 months ago

Much appreciation for the work.

I noticed a 1.5 kHz downshift for correctly when listening to a station in SSB. Can you fix this? BFO = 0.

Checked with professional shortwave equipment.

Best regards Kris1958

This is a bug of Si4732 chip. To fix this I have to align frequency by correction table. To do that I need more space for storing table and new logic, this is not possible to do that without cutting other features.
