Bill, sounds like this is a spike that comes from I-Q imbalance. With most
SDR programs, if you tune in a strong carrier to the left of the center
line, built-in automatic I-Q balancing will attenuate and soon eliminate
this spike, and it won't come back. I don't have a P3 right now, but as I
recall the P3 did work that way as well.
