Hi David, Take a look at this Hackaday article. It suggests that Smart Meters operate in the 900 MHz ISM band, typically around 915 MHz. Here are some links: http://hackaday.com/2014/02/25/using-sdr-to-read-your-smart-meter/ http://bemasher.github.io/rtlamr/ http://www.rtl-sdr.com/rtlamr-rtl-sdr-receiver-900mhz-ism-smart-meters/ http://www.sigidwiki.com/wiki/Signal_Identification_Guide Hopefully this helps you in small manner.

I live where there are "Smart Meters" ... electric utility meters that transmit electrical usage data to the power company. First, I don't know exactly how they work so I am guessing a bit. THE ANTENNA PART - questions 1. Do the powerlines outside and inside the home or business become antennas for a LF or HF or VHF or UHF or Microwave signal to-from these meters? 2. Typically is this data RF signal "ON" all the time? 3. Is the RF signal isolated or blocked or "bypassed" with an RF capacitor to ground so it does not enter the building on which the meter is installed? -- David B.
