As Chief Engineer of a AM Radio Station for 10 years, this issue caught my attention, so I dug more deeply into the facts.
The National Association for Amateur Radio (ARRL) initiated research on this issue in 2013 and did exhaustive lab testing.
Here is a link to the ARRL web page that explains everything in detail....
ARRL Helps Manufacturer to Resolve Arc Fault Circuit Interrupter RFI Problems
They built a test fixture in which could test any type of circuit breaker. In a nutshell this is what they discovered.
Mike Gruber, the ARRL Lab’s EMC specialist, used a 1,000 watt HAM transmitter (more powerful than WVLG The Villages radio) as an RF source. Gruber says he bought one of “every AFCI breaker that I could get my hands on,” but when the Lab began testing them, none of the devices tripped.
A ham in New Mexico who had reported AFCI problems sent some of his breakers to the ARRL Lab, “and those tripped when we tested them,” Gruber said. The problematic breakers were certain models made by Eaton Corporation. “We already had an Eaton breaker, an older model, but it did not trip,” he noted, adding that the breaker had a yellow button. The newer model, which had a white button, did trip in the presence of RF, however, even at power levels down to about 50 watts (a
fraction of the legal HAM power level of 1,000 watts) on 17 meters.
Gruber contacted Eaton, and two of the manufacturer’s engineers visited ARRL Headquarters in August. “Eaton was extremely cooperative and eager to resolve this,” Gruber recounted. “They spent the day with us, going over our test methods and took some of the problematic breakers back with them, eventually developing a modified version.
“We have just finished testing the new version of the breaker, and it did not trip during any transmissions with our 1,000 watt transmitter and in other tests,” Gruber reported.

The suggestions in the forum posts above to have your Eaton breakers replaced is the right process to undertake to get this issue resolved.
