Do you remember when the UHV band was added to the television broadcast spectrum? As the old manual TV tuner in our photo illustrates, the new band brought roughly a seven-fold increase in the number of potential broadcast stations (up from the original 12).

Unfamiliar shouldn’t mean impossible. Here’s how to check a Mazda rotary engine for basic mechanical integrity. An engine most of us have always found interesting, but (if you’re like me) haven’t worked on enough to know as well as our interest would incline is the Wankel rotary used on Mazdas, mostly in recent years their […]

“Simon Says …” Part Two

“Simon Says …” Part Two

As we learned in Part One of this article (Import Service, June 2000), we owe Georg Simon Ohm a debt of gratitude for the electrical principles he published in 1827, which later came to be known as Ohm’s Law. These principles explained in mathematical form the relationship of voltage (E), current (I) and resistance (R) […]
