While we're on the topic of strange-acting analogue TV carriers, I found another one yesterday during an E-skip opening. So far it's a UTV (unidentified television station) as I could not get any discernible video. It really is odd as the carrier seems to FM-modulate then narrow again. It was on channel 5z. Time of reception : 9:28 p.m. EDT. The signal seemed to peak west. Openings to Nebraska-Kansas, Manitoba and Alabama were active at this time. Target Area: Missouri ?
Spectrum capture and audio version are below :
