Sudden loss of sensitivity of reception in 90%

hello, I recently bought an SDR RTL V.3.

I was listening to the Dongle when I realized that he lost 90% at the reception. Now he only hears an FM station 6 km from my home. You don't hear anything else.


When I change an SDR RTL antenna and plug it into an HT, it normally listens to other frequencies.

Check the gain settings.

Could it also be an lightning/ESD event?

already checked everything.

I was listening normally and the SDR RTL suddenly stopped listening.

I also checked for some suturing with the antenna or coaxial cable, but I found no errors.

I changed the antenna, reinstalled it, changed the program, it just lost reception.

the only frequency he hears with difficulty is a community radio 6 kilometers from my house.


Today I tried to call and he is no longer being recognized on the computer.

I changed the USB port, I changed the computer 3 times and I was not successful.

The RTL SDR, which had lost 90% of reception, is now no longer recognized by any computer.
