Lexington, Kentucky #1 global tuner feed.  6930U, constant tone since about 0700UTC.  No idea what it is.  Sorry, no recording at present.

I'm thinking that's local RFI.  I've heard that same noise on 6930 but only on that particular Global Tuners receiver.  It doesn't appear on any other receivers in the same region.  If you get a chance, compare both #1 and #2 Kentucky receivers.

Finally managed to hit globaltuners when both of the Lexington receivers were up, and I think you're probably right.  Only #1 had the tone, not #2.

Interesting bit of QRM to be sitting there with that constant of a tone.  Almost makes me wonder what might be causing it.

My aging Envision PC monitor throws out a carrier at 6930 kHz, among a few other places.  Have to turn it off when trying to pull in NRS.

Heh, in my house, it's 6931 and steady.... drove me nuts trying to ID it until I heard it "blurp" as my wife typed. AH-HA! :D

Peace!
