What can be done about a base holding 19 keyed down for months?

It hasn't been 24 hours yet. Give him a few more hours and maybe we'll see some activity. Maybe?

Unless it is some 1950's diathermy machine, the ISM equipment are locked onto specific assignments like 27.120 MHz. They won't blanket the entire band,

Hate to break it to you, but 27.12 is the “center of the band” The band total band size is 163KHz to either side of that.

The ISM imissons are considered “in band” as long as they are within 163KHz of 27.12MHz. The device does not have to operate at exactly 27.12Mhz. It just has to operate within 163KHz of 27.12MHz.

Maximum Radiated power per FCC quote.
“ ISM equipment operating on a frequency specified in §18.301 is permitted unlimited radiated energy in the band specified for that frequency.”

Emissions outside that band is limited to specific levels.
Chanel 19 falls within that band.

There has been a large increase in industries using 13, 27, and 40Mhz induction and dielectric heaters. Everyone use to use microwave based heaters for a wide range of dielectric heating applications, but people in the manufacturing industry have started to figure out that lower frequencies will produce more effective and efficient heating of the objects in question. It will generate heat deeper in the object than microwaves will. At the same time there has also been a steady move of induction heaters up to the HF range as solid state equipment has made it more economical to produce significant power at those frequencies. So there has been a big boom in industrial heaters operating on the HF frequencies.


We are not talking small stuff. I am talking equipment with effective delivered power somewhere in the 10 to 100KW range.

Even if the production line shielding is 99% effective, you are still talking about 100 to 1000 watts of radiated power.

Only requirement of ISM radiated energy is it can not carry any modulation that may contain intelligence.


That is why I think he may be dealing with an ISM unit.
A normal CB, or any normal transceiver for that mater, will not handle days of dead key, let alone, months.
Even the most stubborn cuss will give up after a while.

What ever is operating is designed for continuous output. And it conducts no intelligible information.
The fact that it falls within the ISM band is what makes everything click in my mind that it is probably an ISM user that is causing him a problem.

If the OP can confirm exactly what is being operated and where it is, the only folks with the power to take action are the FCC, who could start out with a Notice of Violation for intentional interference and a $10,000 fine.

But the FCC lacks the motivation or resources to deal with anything except billion dollar airtime auctions, apparently.

There's only one way to force a government agency to take action, and that's the courts. In a case like this, any federal judge can issue a "writ of mandamus", which is the latin way of saying "Do your job, or you'll answer to me on contempt of court charges" and yes, that means a federal marshal is sent out and told "Arrest that commissioner and bring him to my jail."

You've got to find a really cranky federal judge who doesn't give a damn about making friends or enemies in high places, they really are reluctant to issue these writs. But, first you contact the FCC, with proof of contact. And when that fails, you explore the court system.

And if the court system failed, as one Supreme Court justice once remarked, "If the courts do not give men a remedy, they should not be surprised when men find other remedies on their own."

No easy answers, no easy choices except "Turn it off" and use another radio.

Could be. Years ago in Chicago, channel 23 was 100% useless from a continuous carrier from a heating unit at a plastic factory. But it was very stable, never wandered. I reread the OP and thought that sounds of someone fighting were heard over a mike. But that wasn't exactly the case. So yes it could be an ISM transmitter.

He stated that he heard two people go at it on an unspecified channel. (Most likely a channel other than the continuous carrier. Seeing that it would be hard for someone to receive someone else on a channel for which they are continuously transmitting on.) Then heard through the “grape vine” that they had a physical confrontation after the fact.

But as for as I can read from his statement, he had no direct indication either of them was the direct cause of the carrier. Or that the carrier had anything to do with the disagreement at all. He was the one drawing that conclusion on his own.

Im sure the FCC will just get right on it .. Expect black suburbans to be cruising the area any minute ... Actually NO... Like everyone else said... eventually his PA will burn up and that will be the end...Its CB big deal..

The government now has the ability to pinpoint the exact location of any transmission within seconds via satellite! Government vehicles could be at the scene and set up a perimeter around the source of this illegal transmission within minutes. The offender could then be immediately arrested, and his equipment seized.

Thread closed.

The only real answer is to contact the FCC if it bothers you that much.
