Re: PC (laptop) power induces significant noise

The same for me with a brand new Lenovo Yoga. I have a big FT-240 31 ferrite choke with 12 turns on the usb cable added to their two ferrites built in. I made the same on the power supply cable. The floor noise improves but it is not good as the batteries one.

Re: IF GAIN

I tried to use the Notch too, but the QRM station was too far in frequency.
A remark: I downloaded the SDRconsole V2. Its default, for the IF gain, is -20 dB manual even though the automatic option is available. :?:

IF GAIN

On 10m in USB, the AGC started to work on the modulation of a strong station near my frequency. The RX AGC was set on SLOW as has to be for SSB, I guess. After some attempts I solved the issue disabling the IF AGC on the main settings panel. The question is: what disadvantages have I disabling it? :?.
