Re: Offset center spike?

Yes, I can manually offset with the slider each time but was looking to make a program configuration entry so the offset is retained for me even if I use the zoom or center function.

In general you want to avoid straddling signals across the central spike. Offset it slightly so that does not happen. The central spike will leave a remnant present that is the self-conversion of the LO beating with itself. That's noise that reduces your signal's quality.

One can always put the RX'ed signal to either side of it until SDRC 'tames' it down. i.e. On my SDR-iq RXR's, it takes about 10-15 seconds of use before the DC spike disappears.Not sure how long (if at all) it is corrected using the RTL series sticks.
