Re: Offset center spike?

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.

Here;s some info on the DC Spike;

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.
