I’d like to reinforce Bill’s comment about decoding depth. You really don’t lose much by selecting “Normal” instead of “Deep” decoding. In fact, you lose no sensitivity at all for short pings. The “Deep” setting only improves sensitivity for weak pings that last longer than about 350ms, and it has no affect at all on decoding of “Sh” messages. You can determine, for yourself, how much you’d lose by going to “Normal” instead of “Deep” if you pay attention to the number at the end of the decode line while running “Deep". This number tells you how many 72 ms message frames were coherently averaged to produce the decode. Moving to “Normal” instead of “Deep” will remove all decodes that have either “5” or “7” as the last number on the line. You’ll notice that these are relatively rare compared to 1,2,3, and 4.
