Hi Larry, The tone I'm hearing may be on my cell phone? I'm an old man and I don't rely on cell phones all that much. (Emergencies only, especially when my phone and Internet goes out and I have to call repair service which wastes most of my monthly 100 minute allowance.)

When I am listening to my analog radio I am near my computer. I heard the noise one time on that thing and that is all.

When I was watching that speech I was watching in my living room, but I did not have any of my other electronics turned on.

As for hearing the subaudible tones on Laura Ingram's show it is rare I get up early enough to listen in during the radio broadcast. I subscribe to the podcast, but the tones would not be heard therein.

Thanks for writing.
