FYI In response to Director Ritz, these are the Amazon RANKINGS, of ALL books on Amazon, BASED ON SALES: ARRL Ham Radio Licensing Manual #2,539 (total business = 40,000 books/year) Gordon West Technician #28,627 (total business = 10,000 books/year) Ria Jairam Technician #154,400 KB6NU Technician #842,997 Both our books and Gordon West books are in all the national retailers (DXE, GigaParts, HRO) - the others are not. The bottom 2 books exist, but their sales are de minimis as are most of the other licensing manuals.
