The S meter on my Flex 6500 is supposedly very well calibrated, and it reads out directly in dBm. An empty antenna port on the Flex reads -113 dBm. That would at least verify your signal source. <span><span style="color: rgb(0, 0, 0); font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 16px;">Problem is, I live in Grand Rapids...</span></span></div><div><br></div><div>If you're not super concerned about accuracy, I'd just use any known good receiver to check your signal source.
