Can you receive FM radio on a 3D printer's heatbed?
@repkord asked, and we tested, with some assistance from my Dad, a radio engineer!
The answer is yes, and a video is here: youtube.com/watch?v=BA3_jCst…

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-8k…

We saved our old iMac with @Juicy_Crumb's Docklite — a replacement for the iMac motherboard to give (at least some) old iMacs new life!

The movie 'Fall' has a radio tower in it. Don't let a radio engineer see it 🫣 youtube.com/watch?v=WGzruDpV…

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.

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=4EXsHeSl…

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=PZwDEqto…

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_wTyKsW…

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?
