For example, we learn that the Model S-1 was a TRF regenerative set that tuned from 1.5 MHz to 22 MHz. Coverage of the broadcast band began with the Model S-5, a superhet. The descriptions are augmented by sidebars that alert the readers to schematic errors and differences in production runs. So read the book and drool over the offerings from Hallicrafters, especially those early beauties. The coverage of these products spans the period from 1937 to 1977, and includes an impressive array of exciters, transmitters and transceivers.
Some features found in the early models are unique.
The book contains a great deal of interesting information on these old rigs. These units are also well documented with a separate chapter devoted to speakers. The coverage of Hallicrafters speakers should be especially useful to collectors, since this is a relatively undocumented area of radio collecting. However, the book does not overlook Hallicrafters production of this equipment during the period from 1959 to 1967. Another unknown, or possibly just forgotten fact is that Hallicrafters sold test equipment in wired or kit form during the mid-1960s.
