I'm not familiar with where things are installed on Windows, but you should have an already complete example flow graph named
uhd_atsc_tx.grc somewhere.
It's probably in a directory with a name like gnuradio/share/gnuradio/examples/dtv
Also, the test file is https://www.w6rz.net/advastc.ts (which is noted in the example flow graph).
adv16apsk910.ts is the DVB-S2 test file and will still mostly work, but there will be either video of audio hiccups because it's the
incorrect Transport Stream bitrate.
