ATSC video in 1GHz+

[lnx64]

I was originally thinking harmonics, but I have ruled it out by carrying the radio outside and using a simple dipole. It's weaker, but there. Also, the signal comes and goes. Shows up on other frequencies at times, and it will do this even if nothing in the antenna alignment, or anything else change.

You bring up hams. I was thinking maybe? But, why 12MHz bandwidth? As of right now it's completely gone, and no longer on this frequency.

Is the digital reference carrier approx 0.310 mHz above the bottom edge of the transmission spectra, as per normal broadcast atsc tv?
