This book is a needed break from the certification exam books I've been writing. These amateur radio exam-related books have a necessarily confining syllabus with a defined purpose: prepare the student to successful pass certification exams so they may enter this fascinatingly vast world of amateur radio. This book you are reading is different since I am guided by what interests me personally. Most of these topics are related to some arcane aspect of amateur radio while other topics come from seemingly unrelated material gleaned during my university studies and 26-year university professor day job.
The topics presented in this book include:
A Strategy for LC Filter Design
FT8 Under the Hood
The McIntyre-Schumacher-Woodhouse Music Synthesis Model
Morse Code Generation
Estimating Propagation Distances
Cats Cradle Antenna
Intermediate Frequency Filters
Motional Parameters
RF Mixers
Matching Networks
NanoVNA and Smith Charts
Data Flip Flops

Pretty good product
Style: Single Arm, Size: 13"-34"
Assembly of the actual stand is easy, mounting to a monitor is not because of industrial design fluff. Gotta make the side you DON'T see look "sleek" and "smooth" and "organic" and "integrated" because...reasons. While this is on the manufacturer(s) of the monitor itself, what semi-modern monitor uses 100x100 VESA anyway?
The included long screws are too long. Even using the plastic spacers they'll bottom out with a 2mm gap; add washers and it's a lever arm and not solid or confidence-inspiring. I used a die grinder to remove the excess material closer to 75x75 and used the included short screws, perfect. So either include 25mm screws instead of the 30mm (but then the spacers would be too long), or just update the mount plate to 75x75 only, and throw 100x100 "compatibility" into the dustbin of history where absolutely no one will miss it.
Arm does move/adjust smoothly and is holding a 34" widescreen where I left it 2 days ago, so it IS a great product once it's properly fitted.

Great monitor arm stand.
Style: Single Arm, Size: 13"-34"
Very happy with this product. It's sturdy and easy to install. Love the tilt and swivel feature. The fittings for the stand are very well made. I suggest this for the quality and the price.

Easy to set up & works great
Style: Single Arm, Size: 13"-34"
It was super easy to get set up, came with all the hardware ypu need to install multiple ways. Holds my monitor securely and is still easy to move around. The adjustments are easy to access and have plenty of variation. Great purchase, such a reasonable price.

I love it!!
Style: Dual Arms, Size: 17"-33"
I love this product. I do a lot of gaming and you tube watching. At the same time a lot. With this I keep my desktop clear so I can have my notebooks there and can still have both my monitors up and running. Another plus is if I decide to sit on the couch and play the console I can turn the screen a full 180 degrees so I can setup you tube and play games on the T.V. using the console.
The product itself feels to be of decent quality. It is not all plastic. The clamp is nice and strong.

Gets the job done. Just barely.
Style: Dual Arms, Size: 17"-33"
It holds up my monitor, but just barely, and without any confidence or finesse.
I had to move on from my previous arm mounts, the HUANUO. Those claimed to hold up to a 30 inch monitor and support 20 pounds. When I upgraded to a Samsung Odyssey Neo G8, it could no longer perform its duties. The gas shock was up to task, but the final adjustment piece that tilts it up or down was a hard down.
Queue this piece of hardware! 22 pounds is more than 20, and 32 is more than 30. This time I'm not even technically out of spec. The clamping force seems more than adequate to hold this to my desk. I will, at this point, basically walk you through how I feel about this mount, based on the order of installation instructions.
The way it goes together means that you will have to pull your desk out to maneuver the clamp in place before snugging it back up to the wall, a point in the HUANO's favor since it had a clever leveraging mechanism that lets you hang it with your desk still against the wall.
The way cords route through the arms close to the base means that you have to route them before you put the swivel arm on the base. This is because it has a screw at the front and back to secure the cover, and the angle/height are such that you cannot fit a screwdriver into the bottom one after you mount it. While not impossible to do with it installed, it would involve a right-angle screwdriver. They provide one of those, but the screwdriver bit of it is on the long shaft, and you would need it on the short shaft to get to that screw.
The way the swivel arms mount on the base is less than ideal as well. The arm slips onto a robust metal hub, and you tighten a screw that pushes against a plastic tab that makes it harder or easier to move. The location for this screw faces the wall. So you must turn the arm at an extreme angle to make it tighter or looser. Not a big deal, but noticeable.
Top arms go on smoothly, cable routing is simple and easy. No complaints about this section.
Mounting the monitor. The instructions are to mount the plate to the monitor, and then slide the plate onto the holder and secure it with the screw. I did this for neither of my monitors, although I tried it for my second. My big monitor went smoothly by mounting the bracket ahead of time and just forcing the arm down into position while my monitor rested on my desk. I tried this for my second bracket, but it was much harder to do with the monitor in a vertical orientation. So then I tried to do it the way the instructions wanted. I would have been able to do so, but my monitor has the mounting location set into the back of the monitor. This means that you can't mount it flush and then slide it on because you don't have clearance. So I tried to use the spacers. The spacers aren't spacious enough and the screws bottomed before snugging. While I'm not saying that solution wouldn't have technically worked, I instead reverted back to mounting the bracket first. This time I laid my monitor flat on the desk, reduced the tension in the shock greatly, and placed it into position that way.
At the end when it's complete and setup? It works. It will hold the G8. But just barely. The G8 uses an adapter to go from the monitor mounting points to VESA 100. This adapter sticks out quite a bit from the monitor, which means the weight is further away from the mounting point. Getting the tilt adjustment to hold involved a bigger allen wrench and cranking it further than it seems like it was meant to go. It groaned, but it held. It wants to dip if you mess with it, so I crank it again. Will it one day totally fail on me and point my monitor at my desk? Maybe. But it works on day 1, so that's a start.
