User-selected frequency is shown at spectrogram by short red line. maximal deviation from last user-selected frequency. Second number is global deviation in hertzs, i.e. maximal deviation from current frequency. The first number is local deviation in hertzs, i.e. The numbers to the left of the AFC button determines the limits of AFC. The " AFC" button (auto frequency control) adjusts the long red line (working frequency) to the closest peak frequency. To move a visible part of spectrogram to left or right drag it by mouse with Alt key pressed. " Alt-7" hotkeys change frequency scale of spectrogram. To change the TX marker position, click on the desired frequency by right mouse button (or by left mouse button with "Ctrl" key pressed). It is used to help with zero-beat tuning. The short thick black line is the marker of TX frequency. To change the working frequency, click on the desired frequency (probably a peak). Ruler under this window shows frequencies of sound spectrum.The vertical red line in the top window shows the working frequency of the filter. In the top window the current spectrum of a signal (blue line) and a peak detector of spectral components (green line) is shown.
The working area of the program is divided into three windows, the sizes of which can be changed by the user by dragging the borders.
