wave behavior

Whether it is a stone tossed into a glassy-smooth pond, sound waves coming out of a trombone or electro-magnetic waves enabling radios to communicate, the wave behaviors are direct relatives to the physicist. One such person built a model to demonstrate wave behavior then his employer, Bell Labs, produced a movie of it. I almost called it a video, but […]

I know I am unusual in planning and preparing for such a scenario. I not only think of ME and mine, but want others to have value in their […]

Bitterroot Emergency Radio Plan

BEARS, that is the Bitterroot Emergency Amateur Radio Services, works towards having viable communication resources in place when our neighborhood most needs it.

Frequency […]

Technologically I hang on by my fingernails in this company, but am an organizer, a real one. So I run […]
