The pressure was adjusted to 1800 psi, however, this is the outlet of the regulator. When Cabe breaks off the regulator to release the pressure, there is nothing to restrict it to 1800 psi, it is simply the pressure within the tank making the adjustment was meaningless.

The old TV shows channel 71 on a NTSC TV (analog broadcast), while NTSC went off the air in January 1, 2010. With few exceptions, most over the air broadcasting was now ATSC (digital broadcast). NTSC receivers are incompatible with ATSC signals and would show nothing without a converter. Also Channel 71 was in the Cable Ultra band Frequency range and not OTA as shown.
