Wes Hayward

Wes Hayward is an engineer, author and a renowned Radio Amateur residing in the United States. He holds the amateur radio callsign W7ZOI and has written numerous articles about amateur radio electronics construction, in various magazines. Together with another fellow amateur, Doug DeMaw, W1FB, Wes was responsible for popularizing home made construction of simple radio equipment, which fostered experimentation among radio amateurs.

Wes not only built wonderful equipment, he has always shared his ideas with others through correspondence, mentoring, and publication (both in-print and on the web). Most notably, he has been a regular contributor to the ARRL publication QST, since the mid 1960's. His article Direct Conversion--A Neglected Technique presented the home experimenter with a simple topology that was easy to reproduce. With the evolution to solid state semiconductors in the early 1970's, Wes presented solid state techniques for radio construction through the publication of Solid State Design for the Radio Amateur (co-authored by ARRL technical editor M.F. Doug DeMaw, W1FB).
Wes has authored a total of three books. His latest, Experimental methods in RF Design, (EMRFD) is very popular among the radio homebrewers.

Wes' contributions re-defined the way amateurs build & experiment with radio equipment. The term Ugly construction was first coined by Wes in a 1981 QST article. This term is now widely used within the amateur radio community. He presented a simple-to-build RF spectrum analyzer, which enables home experimenters with test capability previously far out of the reaches of a hobbyist's budget. Wes also published techniques (and software) to assist with crystal filter design. This enabled numerous amateurs (and upstart manufacturers) with the tools and knowledge necessary to design their own high-performance receivers.

The commercial communication world is well aware of Wes' contributions as well. Today, many top-end professional radio transceivers have block diagrams which can be traced back to one of Wes' publications. Many of his receiver / mixer topologies played a key role in the early days of the cellular telephone handset.

Wes received a BS in Physics from Washington State University in 1961 and an MSEE from Stanford University in 1966. He has held his amateur radio license since 1955. He is an avid backpacker & mountaineer. He is well-known for taking his portable radio equipment with him into the hills for QRP operation.
