Try it out if you have a Bolt and let's see what happens. It's supposedly a QAM broadcast. From the DSLR boards: "The NASCAR 5/11 event at 7:30p in Kansas will be available in 4K on channel 1499– however, note that 1499 may not be active until the event starts. Broadcast by FS1 4k." Set a manual recording for 7:30 to 11 PM ET. There is no useful guide data for this blank channel.
