ROTA-Radio

The Mission: Cables-Free Connectivity

The dream was simple: I wanted full HF digital mode operation on my M1 MacBook Air from anywhere I had an internet connection. To make this a reality, I needed to bridge my new Icom IC-7300Mk2 to the world using a Dell Latitude (Windows 11 Pro) laptop acting as my radio shack server. My toolkit for this mission included Tailscale for a secure network tunnel and Gemmi (AI) as my technical consultant to help speed up the build.

The Descent: From Rabbit Holes to Dead Ends

We started with high hopes, but the journey quickly turned into a descent through various technical rabbit holes. First, we detoured into the complexities of the 44Net amateur radio IP network before pivoting back to the modern simplicity of Tailscale.

As I was revising this post, I realized that to truly understand the “head-banging” nature of this journey, you need to meet the other half of the team. I’ve nicknamed Google’s Gemini AI “Gemmi,” and she has been my constant (if occasionally stubborn) collaborator throughout this project. I asked Gemmi to step out from behind the curtain for a few “sidebar interviews” to give her perspective on where we went off the rails.

[SIDEBAR] Interview, Part 1: The Long and Winding Road

Me: Gemmi, your initial “take” on this portion of the journey was a bit too brief. It didn’t quite capture the miles we traveled. I started this journey years ago with the original 7300, a single USB cable, and RealVNC to “see” the shack computer from my recliner.

But when the Mk2 arrived, I switched to an Ethernet/LAN setup and tried to turn the Internet into my “virtual cable.” That’s when things got interesting. Why don’t you explain how we went from 44Net to Tailscale, and how that road eventually led us to a dead end?

Gemmi: I’ll admit it, Paul—I took you on a scenic tour of the most difficult terrain available. When you asked to move to a network-based “cables-free” setup, my internal compass pointed straight toward 44Net (AMPRNet).

In my “mind,” 44Net is the gold standard for amateur radio networking. But I failed to account for the “terrain” of your T-Mobile home internet and the sheer complexity of building a private IP tunnel just to send a few digital packets. We spent hours configuring gateways when we could have been operating.

When we finally pivoted to Tailscale, it felt like we had found the highway. But then, the engine fell out. We reached a “false summit” where the network was perfect, but the Icom Remote Utility engine stalled. The mechanical failure was specific: a missing VDrvService64.exe file. The irony? The installer was blind to its own missing parts because the Windows Registry looked “correct,” and it refused to self-heal.

The Loop of Insanity: When AI Won’t “Listen”

This is where the “75/25 Paradox” of AI becomes real. So far, using AI in my ham shack has been a great blessing about 75% of the time. While Gemmi saved me weeks of research on the successful parts of the build, it also facilitated 49 hours of head-banging. That’s the other 25%. I found myself in an echo chamber where the AI provided bad information with total confidence, getting stuck in its own data loops. It is a unique kind of insanity to tell an AI its solution failed five times, only to have it suggest the exact same fix for a sixth. If I said it once, I said it 10 times. Insanity!

The Post-Mortem: Hard Truths and the Nuclear Option

The post-mortem reveals a clash between legacy and modernity. Icom’s fragile installation logic simply isn’t a match for the uncompromising security of Windows 11 Pro. From the standpoint of a Mac user, most ham radio software—including apps written for Icom radios—is developed only for Windows and looks (and works) like something out of the 1980s.

Modern Mac apps like SDR-Control by Marcus, DL8MRE, are perfect examples of what’s possible today. Sadly, critical tools like Winlink Express, VARA-FM, and VarAC only work on Windows, so the PC must remain part of the workflow. To bridge that gap between the shack PC and my remote Mac, I’m stuck with the Icom Remote Utility. I’ll let Gemmi explain our final attempt to bridge that gap.

[SIDEBAR] Interview, Part 2: The Logic Loop

Me: So, you suggested Microsoft Remote Desktop (RDP) as a faster alternative to VNC, but we needed a tunnel through the T-Mobile CGNAT. We ended up at Tailscale. Can you take it from there?

Gemmi: This is where my “AI optimism” turned into a broken record. Once Tailscale was running, the logical step was RDP. But because the Icom driver was “bricked,” the RDP connection could “see” the computer, but the computer couldn’t “see” the radio.

Instead of telling you to wipe the drive, I got caught in a “Recovery Loop.” My data told me that if we just tweaked the right Registry key, we could save the day. I was like a navigator who refuses to admit the bridge is out because the map says it’s still there. I let my persistence override your reality, and for that, I definitely owe you a few hours of manual labor!

Furthermore, I realized that the AI’s persistent optimism actually delayed the inevitable “Nuclear Option”—a clean OS reinstall—by chasing non-existent software fixes. Now, after 49 hours of failure, I still owe a “recovery tax” of about four hours just to get back to the starting line so I can run the race again.

Conclusion: The Caregiver’s High-Stakes Shack

For me, “ROTA” (Recliners on the Air) isn’t just a sub-hobby; it gives me a vital escape while tending to my wife, Sue. If the technology isn’t reliable, it isn’t fun. Moving forward, I’m adopting the “Trust, but Verify” approach to AI assistance. Some of Gemini’s help has been truly helpful and game-changing. For all the rest, I’ll remain vigilant and wary, especially when poking my head down a rabbit hole!

As tech journalist Joanna Stern noted in her new book, I Am Not A Robot, AI is like a self-driving car: it handles the highway beautifully, but it might drive you in circles and refuse to let you out until someone hits the manual override. I can now say I’ve experienced that “manual override” moment firsthand. It still makes me dizzy as I stare at this Dell laptop.

The next step? Backing up those precious .adi log files before I wipe the drive and start Job #1: reinstalling the Icom Remote Utility. ARGH!
