SINPO 45444 (which is typical) on an SDR in Texas.
0115 - Liquid Radio ID heard.
0127 - Liquid Radio ID
0128 - Multi-tone (i.e., multiple carriers, like fingers on a hair comb) interference starts up. It is taking up 6810-6850 KHz, inclusive. I switched to SAU (sync detector with upper sideband only) and it is mostly OK.
0148 - I had to step away for 20 minutes. QRM is still there but I'm not sure if Liquid Radio is.

I will have to hunt around.
