Unboxing: 25 Watt Radio Power Test & Review! #shorts
Surprising 25-watt peak output on high power AM and sideband modes. This compact radio delivers impressive wattage for its size. Also features CTCS tones and transmit offset for repeaters.
Review of the Kaiweets Muti-Field EMF Detector (#1409)
Kaiweets sent Dave a new meter to review! This meter can supposedly detect RF, EF, MF, Wifi, and even ghosts! Does this meter perform up to Dave’s standards?

The FCC issued a serious enforcement action against Pittsburgh ham KD3ASC for using a modified BTech UV-Pro radio as a simplex repeater that retransmitted Allegheny County’s 911 public safety channel.
In this video, we break down the full FCC document, what rules were violated, and the important lessons every amateur radio operator needs to know.

Thanks for watching!
Some of you may remember in October I went camping in LA with some friends of mine. They let me use this camper in hopes I’d fall in love with it and want to buy it. Well, I finally did. I need to figure out exactly how I want to kit it out but I thought I’d at least show you around, talk about some ideas, and more importantly, hook up some batteries and see how long I can run the AC. I’ll be taking this up for Dayton Hamfest next month as well as Huntsville Hamfest for sure. Other camping adventures are yet to be planned by boy do I want to get out on the road and see the country, activate some parks and just have fun. Here’s some affiliate links to the batteries I’m using if you want to take a look.

Why My 3D Printer Stays REDACTED (Hardware Sovereignty)
👉 This video is a discussion on hardware privacy, data security, and the technical aspects of air-gapped CNC/3D printing manufacturing. It does not demonstrate or encourage the manufacture of regulated items or the bypassing of safety protocols.
States are beginning to explore regulations that could change how 3D printing, CNC machining, and digital manufacturing work in the United States — not by banning machines outright, but by shifting control into software, cloud systems, and approval pipelines. In this video, I break down the proposed legislation, what it actually means for consumer 3D printers, and how features like cloud slicing, remote firmware updates, and restricted file handling could impact what you’re able to make. If you’ve been following developments around ghost gun regulation, printable firearm components, or digital file restrictions, this is where those conversations intersect with everyday tools like your printer.
I also show a practical path forward: how to keep your setup offline-capable, self-controlled, and independent of cloud approvals, including hardware choices and workflow changes that still work today. If you want to build, print, and experiment without relying on external systems, this is what you need to know.
