3-Band Bell EQ Visualiser

This tool visualizes a 3-band bell equalizer with frequency ranges suitable for the Yaesu FT-710. Adjust the center frequency, gain, and bandwidth for each of the three bands (Low, Mid, High) to see how the equalization affects the audio response curve. The graph shows the frequency response in real-time as you adjust the parameters. You can save your settings and load them later for easy recall of your preferred EQ configuration.

Note: Yaesu has not disclosed the minimum and maximum Q factor values associated with the upper and lower settings of the bandwidth parameter. Sensible assumptions have been made for the Qmin and Qmax values, but controls are provided to modify these parameters, allowing you to define the range of the bandwidth parameter according to your preferences or measurements.
