Well that was useful dah.
The Chinese Military immediately purchased the patent rights.
re: “a communication employee”
Never seen that on a job advert ...
Whole bunch of this story missing.
I’ve had those TV set-top active (built-in amplifier) “rabbit ears” create sweeping signals in the 440 MHz amateur band before; maybe they just didn’t know what they were looking at ...
I’ve had six or seven of those in the last 25 years or so, still have one active in the neighborhood five or six houses down, but it ‘sweeps’ through so quickly I haven’t had a need to contact the home owners.
Well, the military started using those frequencies, and it caused similar problems for the owners of that said door openers.
Your title perked up my ears ... I graduated from NOHS 50+ years ago, lived just several blocks from this incident. Nobody ever hears of North Olmsted.
I own your radio spectrum. You rent it from me.
If you want your garage door to work again, PAY ME!
I hate to be the one to point this out, but when WORDS AND SENTENCES are your life’s work, some care should be taken.
To say “to NOT identify,” as written in the article is not right. That is splitting an infinitive. “ To identify,” is an infinitive, so properly it should read “NOT to identify.”
It happens very often, as we all can see the decline of supposed wordsmiths. For this to happen to those in other professions, it is understandable, but it is inexcusable for reporters.
I apologize for taking time for something trivial, but it is just an example that particularly annoys me.
Stuff all has to share the ISM bands, interference is as unavoidable as finding all the stalls are full at a public restroom. No one has any right to expect priority, as long as they’re in compliance with FCC regulations everyone has to share equally.
During the CB craze, some enthusiasts boosted their signals to vastly increase their range. With "skip" (bouncing off the ionosphere to bend around the earth's curvature) CB'ers could talk over vast distances, all the way around the world on a good day.
On not-so-good days their signal bled all over other bands. Dad claimed he could open his neighbor's garage door just by keying his mike. He claimed he could cause radio-controlled model planes to crash as well, if he wanted to.
This sounds similar - cheap or badly modified equipment spewing trash all over the airwaves...
That’s why so many of the electronic devices you own say “FCC Approved” on them.
Well, the fine print on the garage door openers should say that under Part 13, they must accept interference from any licensed user, since they aren’t actually licensed to use the frequencies upon which they operate.
Perhaps the day has passed when the local Ham Radio club would track down the interference just for the practice and then hold a barbecue.
Did they also disable the guy using the device?
Years ago, when a neighbor would get on his ham radio, our tv changed channels.
Had a customer years ago who’s ceiling fan and light would turn on in the middle of the night and wake him up. I asked him what time the neighbor came home from work and sure enough it was the same time this was happening. Garage door opener was on the same frequency so a quick change on the fan controls and bingo - problem solved.
