Ham radio for people with disabilities. A weekly podcast from the Courage Handiham System, http://handiham.org.
Ham radio topics, including accessible equipment, blind ham radio, events, policy in the Amateur Radio Service, more.

There's some stuff on our radar screen this week,
including a privacy issue the FCC is asking about.
But first, we are really starting to notice the longer hours of daylight here in
North America. How does that affect our on the air activity?
It seems like just yesterday it was dark when I woke up in the morning and dark
right after our evening meal. Believe me, I pay attention to this because
I have two dogs to walk. Anyone who has a dog knows that they need to go
out when they wake up in the morning, throughout the day at strategically
planned times, and finally for an evening stroll. You tend to notice when
it is dark outside because you may need to take a light to see and be seen while
walking along the park paths or in the street. During the winter, when the
nights are really long and there are few hours of daylight, you have no choice
but to hitch up the dogs and head out into the dark. Doggies cannot wait
extra hours for daylight.
Anyway, that pretty much assures that I know that there is
more than enough night to go around all winter long. Nights in the winter
are primo for great, reliable skywave communication on bands like 160, 80, and

But first, are you ready - mentally - to accept change?
I was browsing through my digital copy of the recently-released May QST, and one of my first stops was the Eclectic Technology column by Steve Ford, WB8IMY. Steve's topic is "State-of-the-Art Homebrewing", and he covers a circuit simulation program, which allows designers to test a circuit in a software simulation rather than by building a physical circuit. Simulators have been around a long time for pilot and driver training, but for electronic circuits? This sure wasn't on my radar screen, but when I think about it, circuit simulation is as revolutionary a development as there is for homebrewers - or "makers", as they are called today. I think I'd like to retire the term "homebrewer" for ham radio parlance and leave it for use by hobbyists who brew their own craft beers.
Another one of Steve's topics is home circuit board production, but not with chemical etching. Oh, no - this is way different. It's about a $1,500 circuit board printer that "prints" two-layered printed circuit boards to the specs you set forth in your circuit design software.
You can already get circuit board design software for free, and one point five kilobucks isn't that much, either. You can bet that in a year or two the technology will be even more capable and cheaper. 3D printing is now a thing, and the ham radio maker community is on board. Look for replacement parts and original designs to start gracing the ham shack in short order. As if all this isn't enough change to pack into a single column, Steve polishes off the page with news about new very rapid charging lithium-ion batteries using titanium dioxide nanotube technology that can survive 10,000 charging cycles!
