The result was the . The "W" likely stood for "Wireless" or "Workhorse," but by the time the W9 rolled off the production line in the mid-1960s, it had evolved into a three-motor, direct-drive system that rivaled the professional studio decks of the day—only it fit under an airplane seat.

In an age dominated by digital audio workstations, wireless Bluetooth earbuds, and cloud-based storage, it is easy to forget the engineering marvels that paved the way for modern field recording. For audio engineers, journalists, and intelligence operatives from the 1960s through the 1980s, one name stood above the rest when portability was a requirement and failure was not an option: The McGraw Hill W9 Portable. The result was the

However, the DNA of the W9 lives on. The engineering principles—direct drive, mechanical counter memory, and ruggedized aluminum chassis—eventually trickled down into the (the 221, 430, etc.), which dominated field recording until the digital revolution of the 1990s.
