Ferrite—An inexpensive Way for Hams to Improve Their Time on Air (Part 2): DX Engineering High Impedance Common Mode RF Choke Kits

It’s no secret that common mode RF riding on the outside shield of a feedline is a super-villain to Hams, causing interference, tuning problems, erroneous meter readings, and distortion or […]

What is Ferrite Used For, Anyway (Part 2)

In the OnAllBands entry, “What is Ferrite, Anyway?” we discussed what ferrite is and what makes up a “mix.”  We also explored how ferrite behaves at different frequencies. Ferrite has […]
