At first I though this must have been AM broadcast band breakthrough, so I built a little crystal radio, only to discover that the powerful AM stations here were not playing the ZZ-Top style classic rock that I was hearing in background noise. Bert, WF7I, suggested that I listen carefully to the QRM for a call sign. I tried that this morning. I couldn&#8217;t get a clear call sign, but I picked up the unmistakable rhythm of Peter Frampton&#8217;s &#8220;Do You Feel Like We Do?&#8221; Fortunately that song is 1) infrequently played and 2) quite long; I had enough time to take a spin around the FM radio dial. Sure enough, I caught the tail end of the Frampton song on WBIG-FM 100.3 A quick check of the web shows that this is a 50,000 watt station that has its transmitter within about 1 kilometer of my house. Bingo.<br \/>The mic cord is just about 1\/2 wavelength. That would put the high voltage nodes at the ends, right? I notice that the interference drops noticeably if I wind up the cord, and increases a lot if I stretch out the cord.<br \/>I can hear some other stations in there also (one country station). It may be that there are multiple FM stations broadcasting from that antenna site. I can see the tower&#8217;s red lights blinking from my front lawn.<br \/>Thank you Peter Frampton! <\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Listeners noticed that recent SolderSmoke podcasts had some other audio playing faintly in the background.
