Krausaj, there are very valid reason for having the AFCI breakers installed. Removing these, MAY impact your insurance coverage if you have a fire, or example. These breakers are designed to detect an ACRING fault from, for example, a pinched cord.
Since you have continuing problems, I would check with my neighbors to see if they are having problems also. If not, I would contact SECO, and see if they can do some testing on your house to verify grounding and electrical connections. I would also, contact the local Ham radio operator club, and see if they could local the local radio operator. A monitor would let you know if the breaker tripping is occurring when he is transmitting.
Finally, if you do an Internet search, you will find lots of other info (and probably misinformation).
Send me a PM, I have some equipment that might help.
I really caution you against removing these breakers and replacing with regular breakers.
