Ted’s essays

Grubsteak

Also known as Downing Mountain, or the 146.720 North Repeater, this site presents extreme challenges to the engineers keeping it alive for amateur radio users. I put together a presentation for the local ham clubs, but the projection format washed out my drawings making them unusable for the back half of the room. I put them here for anyone who wants to see a pictoral representation of the challenges our tech team is dealing with. […]

2-meter directional antenna for ten bucks

Two way radios, and particularly the little 5-watt Handheld Transceivers (also known as HTs or walkie-talkies) put their little bit of power in every direction. Yet we sometimes know exactly what direction we want to transmit and would prefer all the power go that way. A century ago two Japanese scholars created an antenna design to do exactly that. We call the design by one of their names, Yagi, but it seems the other, Uda, was the real inventor. Such is history. Following 100-years’-worth of radio technician footsteps, I have designed a simple hardware-store Yagi antenna to focus 147 MHz signals in a primary direction. I used some heavy copper grounding wire and a 4-foot piece of PVC pipe, […]

upcoming amateur radio class

My favorite radio instructor is presenting a class leading to the second, middle level FCC amateur radio operations license. Eric brings comprehensive knowledge, empathy, and energy to the classroom. A fine set of qualifications for anyone who wants to learn the subject. If you have your Technician license, Eric will lead you to successfully cresting the next hurdle into the world of short, medium and long range radio communications. If you do not yet have any amateur radio license, grab both the technician and general books and learn from him while you study up for the first … and quite possibly pass them both by the end of class. – Ted – In case you wish to print it out, […]

time warp floor covering

Our bedroom has been mired in 70s shag carpet for two years of our residency. Obviously for over 40 years before as well. Who made this stuff thinking it would sell? What miracle of marketing moved it into people’s homes? What kind of people thought this looked good? Ever? Not me then, now or anywhere in between. Even more mind boggling is the nicely finished hardwood floor the red/orange/green shag hid. Yesterday we began the chore of moving OUT of our ‘master bedroom’, uncovering the hardwood, cleaning it up, hauling a couple hundred unwieldy pounds of stinky 50-year-old carpet outside, then moving back in. Today we finished moving back in and cutting the carpet into manageable, moderately-heavy, stinky chunks […]
