Hi Terry; do you own this home? If you do, I would try snap on ferrite on the hot and neutral to the breakers, trying one of the most sensitive ones first. I have had experience only with GE and Square D AFCI, and short of close lighning strikes, they seem to be pretty solid.
As one who has done inspected service entrance installs, seeing ferrite inside a load center is certainly unusual, but I don't recall any particular rule against it.
You might also do a quick check using a dummy load first, to insure you have a radiated issue, which seems more likely than RF conducted out the AC of your rig. Is this a 12V powered radio with a separate power supply?
