Police Radio Jamming Device Found - Groves, TX

Interesting. I wonder if the jammer targets specific frequencies or is broadband?
More reason to go back to low band. 
But seriously, I bet this happens more than anyone realizes and is more of a threat than streaming.
A large drug dealer infested apartment complex in the big city close to me was suspected of having jamming devices scattered about it. The radio shop was afraid to go there to attempt to locate it and LE for some reason didn't want to escort them. Not sure what ever became of it, but I've not heard anything about it in several years.
No criminal intent intended, but a very common location for jammers is schools. The teachers buy them to keep students off their phone, not realizing they are jamming first responder systems also. One teacher showed me a flyer he had received from the teachers union showing where to purchase jammers. I referred him to the principal and the ISD PD that were with me when I tracked it down.

It was probably just a Baofeng.

I'm surprised that would even work, unless it was stashed close to a tower.
Not get all technical, but that would seem to run afoul of the FCC.
My wife used to teach in an urban high school. Many of the kids used to have two cell phones. One for family and one for "business." I'll leave it to your imaginations to figure out what businesses high school kids could be engaged in.

This is nothing new. At one point people could buy these off Amazon and E-Bay.
Chinese manufacturers + stupid consumers = a wonderful combination.

Correct, but I didn't work for the FCC and it's job security finding all these.
I left it up to the ISD administration to address it.

Since it was in a perps backpack it was likely one of those portable battery powered deals, likely in the upper digit power levels, usual bands and would hit their 800 system portables and mobiles within a bit and knocking out the control channel. An officer in foot pursuit wouldn't be able to radio the pursuit is what I think they thought would happen.

I think there may have some bans to certain products on Scamazon, but then I've seen them relabel these same devices incorrectly to sidestep those bans.

Funny, a Baofeng is so weak, it can't even jam another Baofeng!
Lots of broadband jammers were sold before they became"harder"to find....cell phone (GSM/CDMA/TDMA), GPS and other frequency band devices sold to keep vehicle trackers and cell phone related devices confused (cell phone based ankle devices). Many just look like old school car stereo amplifiers, but with several antennas hanging off of them. Others are like old transistor radio sized devices.....I have seen these marketed to schools and teachers as mentioned above as well. Knocks down cell phone signal for a few feet and certain bands. Just like CCR's, certain vendors and government agencies tend to do too little too late.

Cell phone jammers are very much illegal.

Right.... The actual legal way to do it is the way some amusement parks do it... It's a technical thing that I'm not very familiar with, but there is a way to limit cell phone usage.Cell phone jammers are very much illegal.

The only legal way that amusement parks limit cell phone usage it to demand people keep them in their pockets when on the rides or otherwise keep them away from rides. Many people have been injured by cell phones flying off of roller coasters. If they catch you using one in an inappropriate situation they can toss you from the park. Businesses are not allowed to use jammers, interceptors, or any other device that may hamper cells phones.
I'm basing it on personnel experience (mine was in the past with the 3G system), especially in the German fest house at Busch Gardens.
Sounds like these people that have had similar issues.

I've heard of real deal call jamming, some prisons do it, but it isn't RF jamming its thru the phone companies and its a type of restricted selective service, 911 calls can always go thru along with phones that are authorized to be in the area, think of a prisoner that sneaks in a phone to call out a hit, it won't work.
It could be something like that. It seemed very effective just in that one area, where the performances were (or it was the building).
Thanks
