We've all heard about parametric equalizers and have even had a recent program by Bob Heil concerning this subject. But, what exactly is a parametric equalizer, what can it do for me, and why should I care?
Well, Mitch Hopper, K9ZXO, produced a very short four-minute video that will explain it all in simple language and terms.

MODES, MODES, AND MORE MODES

Modes. There's a word you run across all the time in amateur radio.  What exactly do we mean by mode?  Well, the answer is: it depends on the context in which it's used.  There's modulation modes, operating modes, digital communication modes, and all kinds of other flavors of mode.  K9ZXO takes a stab at explaining some of the possible uses of the word in this five minute "mini-lesson".

On March 3, 2018, the Sangamon Valley Radio Club celebrated its 70th anniversary with dinner and a featured speaker. The even was held at Poe's on the Hill in Sherman, Illinois. Our guest speaker was noted radio and news broadcaster and amateur radio operator, Ben Kiningham. Ben spoke about the long history of the SVRC and entertained us with many pictures and anecdotes from the 1950s and 60s. A good time was had by all.
