Maxi-Core® 20 Baluns and Feedline Chokes reduce or eliminate currents on the outside of your feedline allowing you to hear and to be heard much better. They keep more RFI/BCI […]
There is a lot of confusion about baluns—where you need to use one, what the balun is supposed to accomplish, and even what a balun really is! The term “balun” […]
Station repairs and upgrades can take place all year round, inside and out. That said, Hams who live where the chilly winds blow and the snow flies during the winter […]
Hams are typically less precise in their use of technical terms than are professional engineers and technicians. Nowhere is this more true than in descriptions of signals contaminated with unwanted […]

Amateurs have long used the Amidon (www.amidoncorp.com) part numbering system for ferrite and powdered iron toroid cores. For powdered iron cores, the Amidon part number begins with a T and […]
When you start designing your own circuits, one of the biggest challenges is not obtaining component values, but choosing from many different types of components all having the same value! […]

Transformers for Impedance Matching One of a transformer’s important functions is impedance transformation. Impedance transformation is just changing the ratio of voltage-to-current in one winding to a different ratio of […]
