In 1954, H.H. Scott perfected and introduced the first commercially successful Wide-band FM-only tuner, the original 310(A) Broadcast Monitor, a major factor in the popular acceptance of FM radio for Hi-Fi listening pleasure.

Then, in mid-1961, H.H. Scott was ready when the FCC adopted the current standard (Zenith/GE) for FM-Stereo multiplex transmissions. Anticipating the FCC's final decision they were first-to-market with the Type 335 Multiplex Adaptor.  (Also, see the Type 830 FM Multiplex Stereo Generator and Type 4310 Broadcast Monitor).

By introducing Wide-band technology to its products, Scott's talented engineering team, led by Chief Research Engineer, Daniel R. von Recklinghausen, "future-proofed" their RF products with the first "useable" multiplex output.

Even before commercial stereo multiplex broadcasting was approved by the FCC (in 1961), wide-band tuner design gave superior quality reception. The earlier research on VHF FM receivers by Major Edwin H. Armstrong (see bio by broadcast historian, Donna Hapler), inventor of FM, clearly demonstrated the inherent advantage of wide-band circuitry. Scott tuners were so reliable they were often used in commercial broadcast applications (See FM Relay Networks).

Because of the subtleties of wide-band circuitry, most manufacturers continued to produce relatively "narrow-band" tuners which give adequate but not the best results with monophonic FM. It remained for the FCC to eventually point out the superiority of wide-band design in receiving multiplex: The FCC-approved (Zenith/GE) multiplex system."

  .   .  like any multiplex transmission, will increase energy transmission at the edges of the channel involved. Accordingly, for optimum stereophonic reception the bandwidth . . . must be considerably greater than that of monophonic . . ."

If you could only choose a single vintage H.H. Scott product to own, most agree it would probably be one of the company's sensitive, and ground-breaking tuners.
