Another thing to get used to is the S meter reads the integrated signal power from the entire passband filter, not just the display power in the single FFT bin (the few bins) that goes into a pixel in he panadapter.
This is most easily seen by setting a filter and slowly decreasing the filter bandwidth by dragging filter edges and watching the meter value decrease (unless it was already dominated by a very strong signal).
