Gains and Dynamics

RX and TX Gains Adjustment

Depending on the SDR model, the gains are different and some of the sliders are not used. Experiment to find the optimum corresponding to your configuration.

The dynamics of HackRF or RTL-SDR being only 8bits, a bad adjustment of the gains can result in the appearance of additional lines in the spectrum due to lines which saturate.

Dynamic spectra tuning

For the ‘Waterfall’ and the trace in amplitude of the spectrum, click on the arrow on the right to adjust the sliders. The setting is different for each SDR.

Receiver Squelch

By clicking on the reception mode (NBFM, WBFM or AM), you can set a squelch.
