Question 1: Is there any advantage (or disadvantage) to changing the FFT value in FMP*.CFG? I don't really notice a difference at 16, 32, or 64 and the documentation doesn't really cover what is actually happening other than 64 is supposed to look better. I probably just answered my own question there but I'm interested to hear if anyone has noticed any difference by altering this value.

Question 2: What signal level improvement does each of the blue horizontal lines in FMP* represent?

Hoping for an RSSI indicator in upcoming releases...

Same as SDR# - less CPU load and less spectrum detail with smaller FFT sizes.

10 dB. Easy to see by dropping the gain by 10, 20, 30 dB in FMP24.
