Ted’s essays

possible CME hit here December 1st

This could be an important event to prepare for. If a massive Coronal Mass Ejection (solar flare) strikes the Earth as is a predicted possibility, electronics could be devastated, along with our entire electrical distribution system. This might be an auspicious time to put some effort into a Faraday Cage or two … and employ them for electronic stuff you value highly. I don’t want to overstate the warning, but I think it prudent to put some time in Friday protecting our electronics and have at least half a plan for a complete grid-down power failure. Hope and Faith are not plans. – Ted – Thank SpaceWeather.com for this warning GEOMAGNETIC STORM WATCH (G3): Three and perhaps four CMEs are heading […]

Waves – best demonstration I have seen

Waves on bodies of water behave similarly to all other waves in nature. Understanding wave behavior is important to radio antenna designers; which is a role I dabble in, and aspire to improve upon. I am currently teaching a class on amateur radio to a group of future hams. For their edification as well as my own I went looking for the video below. It was hard to find, so I saved and uploaded it to my Brighteon video channel. During my search, I watched a lot of instructional videos on waves, and in particular on the electro-magnetic waves such as those that carry our radio signals. I have a lot to learn, and many of those were hard for […]

9 week Darby ham class begins Saturday 10/14

I gave it a three year rest for demand to build up. Tomorrow I begin another of my class series to help local people gain their FCC amateur radio operator technician licenses. It is quite a commitment on their parts as well as mine. We will spend a couple hours of every Saturday now through December 9th building in them the knowledge necessary to become licensed, and competent radio operators. Darby Adult Ed does the heavy lifting for me by mailing fliers out to every resident in the area. That shaking of the bushes got enough interest to make the class worthwhile for their program and for me as an instructor. Our community and their neighborhoods gain a few […]

Emergency Broadcast System WARNING!

This video is an important warning. Heeding it is nearly efortless, but requires we do pay attention and take very simple actions on the afternoons of October 4th, and October 11th. At 2:22pm on those days, the Emergency Broadcast System (EBC) has a “test” scheduled which, according to the information in this video, will contain a non-audible high frequency signal with deleterious effects on humans, possible animals and certainly those people who have been injected with graphene. Watching this video may be one and a half minutes priceless to you and yours: There have been uncountable warnings about the destructive effects of 5G. This is not the post to revisit that, but you can see several of them here: https://www.bitterrootbugle.com/?s=5g […]

Communications Basics

Two-way radio communications is a tremendous subject that can and does carry people in many directions. Certainly among the most important are field communications to and from tactical and reconnaissance teams, particularly with some semblance of security or privacy to the information thereby exchanged. Particularly well suited to teaching this fine art is NC Scout. He recently published a book on the subject: The Guerrilla’s Guide To The Baofeng Radio, which I recommend and am buying myself. He also has a web page covering a whole lot more range. I share the outline below, but encourage you to go to the source. Simply click the linked heading. – Ted – The Foundation: Squaring Away Communications Basics Improvised Field Antennas The […]

Guerrilla’s Guide To 2-Way Radio

For my heading, I purposefully modified NC Scout’s bestselling book title that I am discussing in this post. The Guerrilla’s Guide To The Baofeng Radio goes far beyond the make/model amateur radio he recommends in it. I and a fellow active licensed radio operator (HAM) took a local class from him a few years ago. It was extremely informative and valuable. I expect this book to have much of what we learned in that class, and quite a bit more packed into it. I have ordered my own copy, so this is a recommendation in advance of being able to review it, based on what I know of the author and of the subject matter. He created and operates Brushbeater […]

amateur radio Winter Field Day

This will be the first time I have participated in the annual Winter Field Day. I suppose it sounded difficult. It is incredibly easy for any amateur radio operator anywhere to participate at some level. Sure you can pitch a tent in the snow on some mountain-top for the weekend, but you can also sign up and run right out of your normal radio shack – or anywhere in between. All operators are welcome to join in at whatever level suits their situation and inclination. This year the Bitterroot Emergency Amateur Radio Services group, now officially the Corvallis American Legion Post 91 radio club KG7SPL will be running two radio stations in a tent at the top of the […]

plumber’s 10-meter ham radio antenna

One avenue for local two-way radio communication is through the use of the 10-meter frequencies. I have not had a decent antenna for joining the conversation that is exercised most Wednesday evenings at 1915 hours on 28.350 MHz. For visualization purposes, CB radios are just slightly longer, around 11 meters – that is, very similar in antenna requirements – a fairly tall antenna like the spring-mounted whips you sometimes see on pickup trucks. I have had an antenna that transmits and receives ten meter okay, but it is in my little canyon (problem one) and is a horizontal while the rest of the local operators are using verticals (problem two). So I launched a project to design, build and […]

solar controller upgrade

The beast of a solar panel was too much for the economy controllers I tried. As I mentioned in my previous article about it, solar power upgrade, I put an antique ammeter on the incoming power that I could know how much was hitting the controller and a blade switch in the line so I could cut off the incoming juice when it became too much. This was not a system I could just leave on its own. If I was ever going to be able to ignore it, and if I wanted to absorb maximum power from the sun on this system I needed to upgrade the controller. When my refund from the smoked controller arrived I did […]

Ted Dunlap, STEE

You have-to have initials after your name to lend credibility to your projects and pronouncements. My latest creation inspired me to append “STEE” to my name. Further explanation will wreck the aura, but I’ll go ahead anyway. It stands for Shade Tree Electrical Engineer… similar to the Shade Tree Mechanic title I earned repeatedly with my auto/truck/motorcycle/tractor repair toolset. Running a ham radio shack requires steady, clean 12-volt electricity. Handheld transceivers, HTs, or walkie-talkies if you prefer, have their own batteries. Cheaper ones use AA or AAA, but most use rechargeables whose chargers plug into standard 120-volt household outlets. Our mobiles and base units all run on 12-volt direct current in our shacks, vehicles or deployed field stations. I […]

RADIOGRAM

The Amateur Radio Relay League (ARRL) began as volunteer radio hobbyists relayed welness checks from war zones back to families stateside, quickly morphing into passing information traffic back and forth using the budding radio technology. Amateur radio has been innovating ever since. Among the tools developed to insure accurate message handling is the RADIOGRAM. A form that insures the intended message reaches the target intact. Here is a .pdf of that form so you can see it full sized and print your own. RADIOGRAM There are a number of very good handling instructions on the world wide web. Shop around for your favorite: https://www.qsl.net/mingoares/forms/instructions.html http://www.ws1sm.com/Message-Handling.html https://emcommeast2011.s3.amazonaws.com/RadioGram.pdf I made a copy that is as brief as I could while maintaining the […]

two-way radios

can be indispensable in emergencies and other times normal communications tools are not working. For my current amateur radio Technician Class students, I just bought 7 of the make/model I feel gives the best cost/benefit for ham radio operators. The TYT MD-UV390 operates on both the ultra-high-frequencies (UHF) of the FCC’s family radio service (FRS) and general mobile radio service (GMRS), it also transmits and receives on the very high frequencies (VHF) commonly used by hams, public and private agencies for regional communications. Their MD-UV380 is the lower cost version of the same radio without the water-proofing. TYT, also known as Tyterra builds well-reviewed radios in relatively affordable price ranges. The transmitters, receivers, speakers, microphones, displays, controls and antennas all […]
