OTA TV has a rocky road ahead: ATSC3 has a massive chicken-and-egg problem. Will the FCC mandate it in new TVs? Will DRM kill it? That, and everything else we saw and discussed at NAB 2026, in today's video: youtube.com/watch?v=uEP3E-…

@Davesjoshin Right now probably not, but it's something we've enjoyed researching in the past! Tons of microwave towers still in use today (many of the AM/FM towers have microwave dishes off the sides for different relays)

@GeerlingEng Would you guys be interested in a video on the AT&T Long Lines? I feel like those have captured the imagination of a lot of us, would be cool to get you and your dad's perspective.

As always, huge thanks to first responders—and in this case, to the tower climbers who were busy doing their job, maintaining the KSDK tower. I don't think "saving a guy's life by restraining him for an hour 800' in the air" is in the job description, but he did it anyway

I would not want to be a tower climber (or paramedic, not sure if they'd go up) and have to deal with a potentially-intoxicated person climbing up a 1000+ ft tower. They've been repainting the KSDK-TV tower for a couple weeks, which is why guy probably could make it to base.

It's always a good morning when you're picking up some early b-roll of towers for a new @GeerlingEng video...

Just before heading off to #VCFMW, my Dad and I got the Apple II working! I just wanted to show his neat little workshop in a video, and we wound up plugging in the old recapped PSU, and... well, here's what happened: youtube.com/watch?v=4EXsHe…

How's that 1979 Apple II restoration going? Well... for every problem we fix, another one rears its ugly head. And we now have a Mysterious Ticking Noise! youtube.com/watch?v=PZwDEq…

I did not die installing a GPS antenna at the studio with my Dad... and I got to learn some of the tricks of the trade with coax and antennas for permanent outdoor installs from him! youtube.com/watch?v=Sg4U73…

What would *you* build in a mini rack? My Dad and I are heading to NAB and will talk about our most recent mini rack builds at an Ennes workshop on Saturday! We've learned a lot, and are excited for the future of the mini lab—for radio, homelab, etc. youtube.com/watch?v=g_wTyK…

Delete! Delete! Delete! The FCC asked what regulations should be deleted from its books. Is it good for broadcast radio? Bad for hams? What would we delete? Today's video: youtube.com/watch?v=LCd-vp…

Automakers spent nearly $30 million dollars fighting against an AM radio mandate, but the US government seems ready to pass it. Here's a quick overview of the situation: youtube.com/watch?v=587Q2K…
