Brightness and contrast allow you to tailor the display to your own eyes. In my own

experience I have never used the non-default (center) positions for either, but it's there if you

need it. Double clicking the text Brightness or Contrast will reset the sliders to their defaults.

Speed controls the update interval of the spectrum with 0 being slowest and 5 being fastest.

Slower update speed can provide a more sensitive display (due to averaging of spectrum

intervals into single lines) and uses less CPU. Faster update speed allows you to see shorter

duration signals more clearly to perhaps identify QRN/QRM or see non-JT65 signals of a brief

duration.

Gain simply increases the 'visual strength' of the spectral lines. In some case where one has

a weak, washed out looking display adding a little gain can improve it... but... generally you

would leave gain at zero (0).

Smooth can drastically improve the spectrum display by some aggressive averaging of the

spectra. This averaging tends to bring out the signals while dropping the noise. The only

drawback to smoothing is that very strong signals will overload the calculations leading to

gaps in the display.
