Actually that is something I tried to find out today. I callled my utility company and the lady I talked to didn't know if they were called that. She said she had never heard that name. I left a message for someone to call me about it. I did find out that mine was put on my house almost two years ago. I'm going to look up my dental dates and see how they coincide with that. My stomach hurting much more was just about 30 days ago.
The lady I talked to didn't even know if it is radio frequency but just knew that it is digital. She said it comes in on the electrical wiring. I might can find out by looking at the meter and comparing it with those I see online.
I had my husband print off a site titled "smart meter health complaints" and I still have 'grzbear's info.
