Strange Behavior Near 20KHz

While trying to receive WWV at 20KHz I noticed this strange "zig-zag". Look at the left and right of the waterfall.

WWV is on 60khz. That is what my so called "atomic clocks" synchronize to. Long ago WWV was also on 20khz but gave it up some time ago.

I have been using online receivers because of strong data hash interference in my neighborhood that I believe is caused by Uverse squeezing up to 100mb/sec through ordinary pairs of wires. I don't have Uverse but neighbors do. williamhassig@yahoo.com
