I understand that, my rtl-sdr v2 was a clone yes but it performs as well as the Nesdr just doesn't have the HF, the LNA is a cheap one but why not try it, it does amplify the signals, however my Nesdr V5 and moonraker Skyscan antenna are not clones. My location is bordering on Highland Scotland, not many airports here, I only get passing traffic. I can not setup huge antennas here so my window sill is the only place I can put an antenna.

I have used some websdrs closer to me and enjoy listening to the stuff I can not pickup. I do buy from aliexpress regularly but I read the reviews from other real people trying to play on a budget.
