I bought an industrial radio controller made in China that transmits on unauthorized frequencies in the US. As it turns out, there are many of these knock off units being sold on ebay, Alibaba, etc. In order to safely test the units, I used an RF enclosure to be... show more

It looks like wrong interpretation. Input of your SDR is overloaded by a strong nearby signal and mixer inside produces images. It happens not becuse there is transmission on wrong bands, but due to lack of filtering in SDR. Try to capture the same 30m from TX.

I'm transmitting on the same freq for the replay attack and it works...

If you receive a nearby TX, that works, for example, on 433 MHz, and use an SDR without good filters (like B210), you may receive the same singlan on other frequencies. The same work in opposite direction. Good isolation between TX and RX required for such tests.

You are the best

Anyone can buy aviation radios. Heck two of my handheld Ham radios can transmit in the aviation band.

I like Linux os, Gqrx app. 📡 It is fun to hear stations.🎤 With a fm tuner usb, ant 🐜

I mean.. What's the point? You can only use them in a special lab?

What is the signal range and what are the implications? Is this basically a backdoor? I am unable to watch the video at this moment but hope to do so soon

fark i got alot to learn still

What's your go to for USRP maker and RF enclosure?

if anyone has gotten into AI and got bored. this is your next hobby.
