  • Ted Turner's Satellite Loophole That Built Cable News

    Send Fan Mail

    Ted Turner died on May 6, 2026, at 87. Most tributes will focus on CNN and the billion dollars to the UN. But the moment that mattered most for broadcast history happened on December 17, 1976, when Turner beamed a struggling UHF station up to RCA's Satcom 1 and invented the superstation.

    WTCG was a money-losing Atlanta station running old movies and Braves games. Turner's lawyer found a gap in FCC policy nobody had bothered to close, and within two years, over two million cable subscribers were watching a local station from cities that had never heard of the Braves. That gap is where cable giants like ESPN, MTV, and The Weather Channel came from.

  • Why Broadcast Engineers Are Vanishing From Radio

    Send Fan Mail

    Most of America's radio stations no longer have a chief engineer, and nobody notices until a tower goes dark or the FCC fines start piling up. One station sat silent for six months because no one knew the transmitter had failed. That's not an accident. That's what happens when the people who keep the signal on the air get replaced by remote monitoring and a maintenance budget line.


    I break down how deregulation, consolidation, and years of low wages hollowed out the engineering ranks. SBE membership is shrinking, the median age keeps climbing, and the people coming in aren't keeping pace with retirements. Meanwhile tower theft and aging infrastructure keep raising the stakes.


    This isn't just a staffing problem. Chief engineers are the reason the signal stays clean, the emergency systems work, and the station stays compliant. Lose them and you lose the reliability the whole public safety layer depends on.

  • Why the FCC Public File Can Cost Your Station

    Send Fan Mail

    The FCC's public file used to be a dusty binder in your lobby. Since 2018 it's a searchable, timestamped online record anyone can dig through, and the political file alone has produced some of radio's biggest enforcement fines, running into six figures.

    I go through where most violations actually come from: forgotten issues lists, missed quarterly reports, late political file uploads. The rules haven't changed much since the 80s, but the transparency has, and sloppy compliance is now a time bomb that goes off at license renewal.

    If you're an engineer, GM, or station owner, it's worth knowing exactly what's in that file and making sure it's right. Nobody's flying under the radar anymore.

  • LocalSend: Free Cross-Platform File Transfer Tool

    Send Fan Mail

    Moving a file three feet shouldn't require a round trip to a distant server. LocalSend is a free, open source app that moves files, folders, and text directly over your own network with end-to-end TLS and no accounts, ads, or tracking. If you live with a mix of Windows, macOS, Linux, Android, and iOS, it's the rare tool that treats every platform like a first-class citizen.

    I start with the familiar pain: emailing yourself photos, juggling cloud links, hitting the wall when AirDrop meets Windows. Then the design that fixes it: local discovery, a small HTTPS server on each device, and direct encrypted transfers at LAN speed. No relays, no Bluetooth handshakes, and the no-internet requirement is sometimes a feature, like on a travel router when hotel Wi-Fi is garbage.

    I also cover the failure modes honestly, because "devices don't see each other" has real causes: mismatched SSIDs, AP isolation, strict firewalls, and VPNs hijacking local subnets. There's a short checklist that fixes most of it. If you know someone who still emails themselves attachments, send them this one.

  • Why Crowded Buildings Kill Your Cell Signal

    Send Fan Mail

    You walk into a big box store with full bars and walk out to a flood of missed notifications. It's not your phone and it's not your carrier. It's physics and congestion colliding. Buildings act like leaky shields, and crowds create digital traffic jams.

    I break down both forces. The structure: metal roofs reflect and absorb radio waves, concrete and rebar soak up what's left, steel racks and coolers scatter the rest, and even that sleek glass storefront can have a metallic coating bouncing your signal back out. The people: hundreds of shoppers and staff devices sharing finite tower capacity, so a busy Saturday turns decent bars into unusable bandwidth.

    The fix takes seconds: turn on Wi-Fi calling, force your phone onto Wi-Fi with airplane mode when needed, and drift toward the leaky spots near doors and big windows. If your signal only dies on weekends, that's your congestion clue right there.

  • Your Satellite Calls Aren't Encrypted. Here's Why.

    Send Fan Mail

    Your phone call might have traveled 22,000 miles through space with zero protection, and someone with an $800 satellite dish could have heard every word. A new study from UC San Diego and the University of Maryland intercepted real, unencrypted satellite backhaul: voice calls, text messages, login credentials, and DNS queries, all pulled out of the air with consumer hardware.

    I explain how everyday data ends up on satellites in the first place, remote towers, ships, aircraft, rural networks, and why so much of it stays unencrypted while TV signals have been scrambled for years. Vendors sell encryption as an extra license, carriers downplay the risk, and recent telecom cybersecurity rules got rolled back.

    Then the part you can control: end-to-end encrypted messaging instead of SMS, a trusted VPN in remote areas or in flight, and HTTPS and official apps for anything sensitive.

  • Why Local Radio Stations Are Really Going Dark

    Send Fan Mail

    Local stations are going dark across the country, and blaming streaming only tells half the story. Media consolidation, voice tracking, and corporate cost cutting hollowed out AM and FM from the inside. Strip out the local DJs, local news, and community connection, and you're left with a zombie facility running a cookie-cutter feed from another state. Then everyone acts surprised when listeners leave.

    I get into what local radio does that algorithms and push alerts can't: city council meetings, high school sports, bridging the digital divide in rural areas, and being the trusted voice when the power's out and the cell network is down.

    The stations that survive in 2026 are the ones doubling down on being stubbornly local, with streaming, social, and podcasts as extensions of that, not replacements for it. If your town still has a station that sounds like your town, this episode is about why that matters.

  • MaxxCasting: Fixing FM Radio's Coverage Problem

    Send Fan Mail

    FM coverage maps look bold and confident, but the actual audience listens six feet off the ground, weaving between buildings and hills where signals get chewed up. That's where audio turns fluttery and listeners quietly tune away. And the old "just add a booster" fix can make things worse in the overlap zone.

    MaxxCasting, built by GeoBroadcast Solutions with GatesAir hardware, is cellular network thinking applied to FM: multiple low-power directional booster nodes on the same frequency, engineered with terrain data and time-aligned so the handoff in your car is seamless. The stakes go beyond sound quality. If the Nielsen PPM can't decode your signal, your listening doesn't count, your ratings slip, and advertisers never pay for the audience you actually have.

    I also cover the question engineers always ask: how EAS fits into a synchronized booster network, what changes with zonecasting, and why the NAB still has concerns about scaling it in the real world.

  • Broadcast Network Security After the FCC Router Ban

    Send Fan Mail

    The FCC put foreign-manufactured consumer routers on the covered list, and if your facility is running one of those boxes in a mission-critical spot, it's time for a hard look at the rack. I break down what the new rules actually say, what's still unclear for brands that design in the US but build overseas, and why the real risk isn't the policy. It's what happens when that budget router dies during morning drive with no backup plan.

    Then real alternatives that don't need enterprise budgets: pfSense and OPNsense handle VPN tunnels, VLANs, intrusion detection, and full firewall management on hardware you might already own. I share firsthand experience running pfSense on a repurposed Dell desktop across multiple sites, why a known-good backup router matters, and how WireGuard has become serious remote access. If open source support isn't in-house, a local MSP can wrap a contract around it for less than most big vendor solutions.

    Also in this episode: a local ownership win in Brookings, South Dakota, where the people running the stations are buying them. A rough FCC inspection story out of New Jersey with tower lights, blocked access, wrong power, and EAS gear that wouldn't turn on. The FCC's HD Radio digital power changes allowing asymmetric sidebands up to minus 10 dBc on eligible FMs at 106.9 and below. And the C band squeeze, with legislation pushing an auction by mid-2027 while rural stations still relying on C band often don't have the fiber options to transition smoothly.

  • I Built My Own Networking Cheat Sheet. Here's Why.

    Send Fan Mail

    I stopped waiting for the "Ugly's Electrical Reference" of networking and built my own. When you're standing in front of a switch at 11 p.m. and need the exact Cisco IOS command, a clean Wireshark filter, or a subnet answer right now, generic documentation and endless search results are a trap.

    I came up through audio, video, transmitters, and signal chains, then had to learn IP networking later while working alongside engineers who recall configs from memory. So I built a locally hosted single-page web app with AI assistance: no logins, no cloud, just a dark-mode reference with categories, quick tools, and a search bar. Subnet math, common ports, the OSI model in plain English, VLAN configs, Cisco command reminders, and broadcast-specific stuff like PTP and AES67 troubleshooting notes.

    The twist: the hard part wasn't the code, it was naming what I actually needed to know. Writing better prompts forced me to identify my knowledge gaps, and editing the output turned the guide into a record of my learning. I also take on the "AI is killing fundamentals" argument, because for this use case, I don't buy it. Repetition plus a personal cheat sheet moves knowledge off the screen and into your head.
