Does anyone know the frequencies of the signals that are causing AFCI breakers to falsely trip?

So far, it looks like 10 - 18 MHz. For ham radio, that would include the 15, 17, 20 and 30 meter bands. There may be more, but these have been discussed as problems on the Internet for years.
Mostly Eaton AFCI breakers have problems with radio. I do know one instance where the Eatons were replaced with SqD and that was the end of the trouble.

There are threads that reported GFCI trips caused by VHF and UHF two way radios. 150MHz to 900MHz.
