See How a Schematic Diagram is ACTUALLY Visualized

“How to read an Electronic Schematic” by Paul Wesley Lewis

Wonderful example of how to visualize and equate the schematic diagram with the actual circuit build out.

How Do I Read a Schematic Diagram?

How to Read a Schematic by RimstarOrg 

If you are going to build a simple crystal radio, a QRP rig or even a 100 Watt HF transceiver, you are going to want to understand how an electronic schematic diagram is read.  It’s not that difficult.  RimstarOrg has a great video on understanding the basic concept of reading a schematic.

 

Multimeter Tutorial by AfroTechMods

THE BEST Multimeter Tutorial

The voltmeter… the Volt-Ohm Meter… the Multimeter… digital or analog… continuity… amperage, voltage and ohms… COME ON, MAN!  What is it and how hard is it to use in the every day life of a ham radio enthusiast or just someone working in their workshop?  Once again, Afrotechmods has an excellent tutorial on his YouTube channel for us to learn from!

 

 

What the heck is an Amp-Hour?

Regardless if it’s your flashlight, your 2 Meter hand-held radio, your QRP rig, your Field Day station(s), your APRS setup, your balloon launch radio transmitter, your trolling motor, your emergency preparations or your personal GoBox… understanding how long those batteries that supply operating power will last becomes quite important.  It will also assist you in deciding what battery to select for a particular project or product.  Afrotechmods has several excellent YouTube videos on his channel that we all can enjoy!

ExplainingComputers YouTube Channel, Christopher Barnatt, explains USB 3.0 and how it compares to USB 1.1 and USB 2.0 and data transfer rates.

Do Volts or Amps Kill You?

Does Volts or Amps Kill You? Voltage, Current and Resistance

This should be a good lesson for everyone, especially Hams that tinker and homebrew serious radio equipment.  You’d be surprised how much is too much!  Safety around radio equipment, coaxial cables, power chords, power lines, lightening storms, grounding straps and towers needs to be at the forefront of our mind.

Excellent YouTube video by RimstarOrg.

 

Portable Battery Box for Kayak… or Ham Radio

There are a ton of variations of portable battery boxes and unbelievably expensive if you buy they retail.  I like building projects at home, so here is another battery box with a very different form profile from some of the other videos on my blog.  DIY!  Here is a video from Derek Dickey on YouTube of his own kayak fishing GoBox.

 

Portable Power Box

Battery Box, Simple Portable Power by KC6TYD

I built a portable battery box years ago out of a used small white lard tub from a Mr. Donut shop here in town to carry 2 small batteries to power “things” on camping and canoe trips.  It charged from a flexible solar panel that I laid atop my packed canoe when fishing on the rivers of West Virginia.  Then at night I had a string of 12 volt car lamp bulbs that I would string up around the campsite for some excellent lighting.  It also had a small LED inside the box that would glow amber all night so that if you needed to get up in the middle of the night you can set the small tub beside the tent flap and push a little button to kick on the rest of the lights.  I like this set up from KC6TYD, too!

GoBox Ideas

GoBox Update from KC6TYD

I am getting ready to put my ham radio station back together after being QRT for a number of years.  When I think about the VHF/UHF section of my station, I may decide to configure those particular technologies in a GoBox, of some sort.  I really like the idea of being able to “pack-n-go” in the event of emergency comms or Field Day type of activities.

 

Back Up Solar Power for Ham Radio

Harbor Freight Solar Panel for Ham Radio

I spent a lot of time on a medical mission trip to Mali, West Africa years ago optimizing their solar power system.  (Constant dust on the solar panels from the Harmattan winds was a battle for efficiency.)  This is an interesting video done by KC6TYD about his first experience with solar power in the ham shack.  (This only about the concept, not an endorsement per se of Harbor Freight or the manufacturer.)  But I am definitely interested in some solar projects here at home in the future.

Get the right O-Scope!

More O-Scope training!  This guy is so good at teaching it!

Bought my first O-Scope at Dayton Hamvention in 2015… here is a good way to learn!

Arrow Antenna Bracket by Randy K7AGE

If you are interested in a relatively easy way to chase “The Easy Birds” (amateur satellites), K7AGE can help you get set up and successful QUICK!

Ham Radio Satellite Arrow Antenna

How to track satellites with K7AGE… Randy is great at explaining the how and why!

Ham Radio AO-51 Satellite with Randy, K7AGE

Randy K7AGE does a great job explaining how the satellite pass will work with minimal ground station equipment.  It is a really cool way to communicate and anyone with a Ham Radio License can do it!!!  Think about it… you are shooting signals to and from something the size of a Cantaloupe that is more than 22,000 miles away from the earth… and MOVING at 17,000 miles per hour in a circular orbit… with a $30 handi-talkie!
