zenith: Royal 1000-D; Trans-Oceanic vs.Royal 1000

In the book "The Zenith Trans-Oceanic, the Royalty of Radios", by H.Bryant and N.Cones, we find the following:

quote...
A July 3, 1958 press release introduced the Royal 1000-D as a version of the basic Royal 1000, but with a $25 option providing a 9th band (long wave) for "CAA weather / navigation".
The Royal 1000 and the Royal 1000-D were advertised and sold simultaneously.

...As you're probably aware, the long wave band was not used for broadcasting in the USA as it has been in Europe. In North America, the long wave band was primarily used for marine navigation aids (radio beacons and LORAN) and coded weather information (using numerical data in Morse code; if I remember correctly, the included log book tells how to interpret the data).  'CAA' stands for 'Civil Aeronautics Administration', so one can logically conclude that the coded weather transmissions were intended for aircraft.  In the late 1960s, the National Oceanic and Atmospheric Administration (NOAA) began broadcasting weather information in the 162 MHz range (which is why the later 'Royal 7000'-series Trans-Oceanics added a 'VHF Weather' band).  That and the advent of GPS have largely rendered these transmissions obsolete, and there isn't much activity on the long wave band in the US anymore...
