Right now at 22:13 UTC on Nov. 17 I'm hearing a broadcast station on 13670 kHz with a strong continuous tone in the background. The audio of the voice is very garbled, but it sounds like the language may be Spanish. I've found no listing for this time and frequency. There's some fading, but it's coming in with the same signal strength on both my R75 with 23 ft. of wire and my portable with just the whip. The tone is not from a heterodyne, and my radios are in AM mode. Does anyone else hear this?
