Re: Gain settings with Firmware 1.6.2 #airspyhfplus #bestpractice #firmware

Here are three spectra around 738 kHz taken with a) FW 1.6.2;  b) FW 1.6.2 plus an external 20 dB attenuator;  c) FW 1.6.1.
As you see in case a) the reception is totally washed out. The only way to get a reasonable spectrum with 1.6.2 without the external attenuator is to turn off the AGC in SDR# and insert a lot of HF attenuation from the panel.
