The modular design of the FT-221, where removable circuit boards allowed radio hams to modify their FT-221 either by replacing specific components or even replacing the whole board. One such replacement is the mutek replacement front end board which improved the front-end sensitivity. The open format of the internal construction also allowed the transmit and receive cables to be brought outside the case to use a low-noise coaxial relay.

Famous quotes containing the words technical and/or description:
“The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
—Nancy Hale (b. 1908)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
