DHS: Signal Jammers Pose Threat to Police and Aviation

Friday, June 20, 2025

DHS informs: Customs and Border Protection (CBP) has seen a roughly 830% increase in seizures of Chinese-made signal jammers since 2021. Signal jammers can be used to disrupt a range of radio frequency channels, and pose a threat to emergency response, law enforcement, aviation, and critical infrastructure. Criminals allegedly jammed calls to local police during home invasions or bank robberies in Florida, Illinois, Ohio, Pennsylvania, Texas, Vermont, and Virginia. Federal law already prohibits the private import, operation, marketing, or sale of any signal jamming equipment that interferes with law enforcement communications, GPS, or radar. Signal jammers are banned in Beijing for public use. If you Google "signal jammer," you will be lost in a forest of these Chinese-made devices.

Jammers can also scramble surveillance footage in banks, hotels, restaurants, and government facilities. Humans are now exposed to electromagnetic fields (EMF) and radiofrequency (RF) radiation at unprecedented levels. The FCC admits no 5G safety studies have been conducted or funded by the agency or telecom industry, and that none are planned. Excessive exposures to cellphones and Wi-Fi networks have been linked to chronic diseases such as cardiac arrhythmias, anxiety, depression, autism, Alzheimer's and infertility.

Is this a new issue, or just an issue because the Chinese now seem to be providing cheap jammers?

I ask, because back in the 1980's I used to listen to radio communications. My equipment had the ability to receive radio communications from 0.03MHZ up through 2GHz. Yeah, so little time, so much to listen to.

OK, back then, I used to listen to submarine communications. But, just when things would get interesting in those communications, one of the communicators would say something along the line of ~let's go green.~ After that, the comm I was listening to became unintelligible. (imo, I viewed that as A Good Thing).

OK, that background story aside, also back in the day I noticed jammers.

So, jammers are nothing new to me, but maybe cheap Chinese jammers are a new thing.

Hi Lamplighter: The issue is the increase in the influx of these signal jammers which have been used to commit crimes in the US and interfere with GPS and aviation communications. We are already experiencing a decline in air safety under 'President Plane Crash.'

PS: A few years ago I almost bought a Ham radio, but opted against it. I'd rather read, blog, play some music, cook for my wife, or write short stories.

No TV.
