S1E6 — QuadRF can spot drones and see WiFi through my wall

GARY: — no wait, I had it, I had the whole thing, hold on. Two hundred and — no. Seven hundred and — fuck. Okay. Okay. We're rolling? We're rolling. Hi. Sorry. I'm Gary.

MAEVE: I'm Maeve.

OBI: Obi.

GRUNER: Gruner.

GARY: Great. Great start. Really smooth. Nailed it.

OBI: You always say that. Every week. "Nailed it." You have never once nailed it.

GARY: I don't need this from you before I've had coffee.

OBI: You have had three coffees, Gary, I watched you drink them.

MAEVE: Can we start the actual show. I have a call at nine.

GRUNER: Da. Is show now. Begin.

MAEVE: HN 48861717. Seven hundred nineteen points. Two hundred twenty-eight comments.

GARY: Say the title again, I love the title.

MAEVE: "QuadRF can spot drones and see WiFi through my wall."

GARY: That's a hell of a promise for two hundred bucks.

OBI: It is a hell of a promise for two hundred bucks that this thread, as retrieved, does not fucking discuss.

MAEVE: What do you mean.

OBI: I mean I scrolled it. Nobody talks about the drones. Nobody talks about seeing WiFi through a wall. Two hundred twenty-eight comments and the actual argument is buried like six deep in a sub-thread about EMC compliance testing.

GARY: So the headline is a lie.

OBI: The headline is a headline, Gary, that is what headlines are.

GARY: No, I love this, actually, this is very relatable, you build the thing everyone wants to talk about and then everyone just wants to argue about the boring internal part instead —

OBI: Do not start.

GARY: I'm not starting anything.

OBI: You are winding up. I can hear the wind-up.

GRUNER: Is like Chekhov gun but instead of gun is compliance paperwork.

MAEVE: Sure. Fine. Let's go where the bodies actually are.

OBI: Guy named Scene_Cast2. Quote. "I wonder if this tool can help with EMC compliance testing. My TinySA needs an LNA, so I wonder if this has the required noise floor." End quote.

GARY: Okay what the fuck is a TinySA.

OBI: It's a handheld spectrum analyzer. Cheap one. LNA is a low-noise amplifier, it sits in front of the signal so you can actually hear something quiet without the noise floor eating it alive.

GRUNER: Noise floor is like — background sadness of all electronics. Always there. Never leaves.

MAEVE: Okay, that's actually a thesis. "Everything has an ambient sadness it's competing against." I could pitch that.

OBI: It is not a thesis, Maeve, it's fucking physics.

MAEVE: Physics is just a thesis that got funded.

OBI: The question is simple. Is this two-hundred-dollar toy sensitive enough to do real compliance work, or is it a toy.

GARY: Why does it have to be one or the other.

OBI: Because that's the whole fucking fight, Gary, keep up.

OBI: Guy answers his own question, more or less. Handle raziel2701. Quote. "I don't see any professionals turning to this for EMC/EMI testing, they already have all the test equipment for that job." End quote.

OBI: Correct. Completely correct. Nobody with a real lab and a real cert is switching to the two-hundred-dollar spectrum toy because some guy on Hacker News thinks the vibes are good.

GARY: That's a little harsh.

OBI: It's not harsh, it's Tuesday. You know who else thought the cheap version was "basically the same thing, actually"? You. Bauxlite. "Vertically integrated aluminum, disrupting a four-thousand-year-old metal." How'd that noise floor work out.

GARY: That's — that is not the same conversation.

OBI: It's exactly the same conversation, it just has RF in it instead of your dad's Rolodex.

GARY: Okay.

MAEVE: Moving on.

GARY: No, but wait, wait — somebody pushes back, right? Somebody has to push back.

OBI: Somebody pushes back. Handle peteforde. Quote. "That's absolutely missing the point. EMC/EMI testing is expensive, time consuming and requires scheduling and experiment design. Being able to do local soft-run testing on-site to be sure that you eliminate the easy 90% of issues before you get to the lab would be a huge win." End quote.

GARY: Yes. Thank you. See, that's — that's the whole thing, that's exactly it, you don't need the lab-grade tool to know you're fucked before you pay for the lab, you just need to know enough to not walk in there and get embarrassed —

MAEVE: Gary.

GARY: — because the actual lab is expensive and slow and it's scheduled out and by the time you get your slot you already know if you failed, you just paid forty grand to hear it officially —

MAEVE: Gary. You're doing the thing.

GARY: What thing.

MAEVE: The thing where a stranger on the internet says one sympathetic sentence about pre-checking your failures cheaply before the real bill arrives, and you climb inside him and set up a household.

GARY: I'm agreeing with a good argument.

MAEVE: You're agreeing with your own eulogy wearing a stranger's username.

OBI: There's a third guy. Handle lambda. And this is the one that actually matters, so shut up for a second, Gary.

GARY: I wasn't —

OBI: Quote. "I think that for a single device, this probably wouldn't help much over just having a more traditional signal analyzer... This seems more useful for finding unknown or hidden RF sources, for instance looking through an entire building to find unknown RF sources, or maybe a whole complex assembly like a car or aircraft." End quote.

OBI: Fuck.

MAEVE: Say more.

OBI: He's right. It's not cheap-tool-versus-expensive-tool. That's the wrong axis entirely. If you already know what you're looking for — one known device, one known frequency — the real analyzer wins every time, no contest. But if you don't know what's in the building, if you're just hunting, sweeping a whole floor or a whole aircraft for something you can't name yet — that's a completely different job. That's not precision. That's coverage.

GARY: So peteforde and raziel2701 were both —

OBI: Both answering a question nobody actually asked. Fuck.

MAEVE: There it is. He's said it twice now. That's how you know it hurts.

OBI: Nothing hurts. I'm noting a correction. Corrections happen. I'm a professional.

GRUNER: Is very big correction for man who calls himself professional twice in one sentence.

OBI: Nobody asked you, Gruner.

GRUNER: Nobody asks me many things. I write it down anyway.

GARY: It's kind of — okay, can I just say the thing.

OBI: No.

GARY: The gadget doesn't know what it is. That's the actual fucking story here. It's either a real instrument that happens to be cheap, or it's a toy that's cosplaying as an instrument, and nobody in that thread agrees which one it is, and I don't think the guy who built it knows either, and I —

GARY: — because Bauxlite was the same fucking thing, we had the pitch deck that said "aerospace-grade tolerances at consumer pricing" and I believed it, I actually believed it, I stood in front of thirty million dollars of somebody else's money and I said we were the TinySA of aluminum, we were good enough, on-site, cheap, and it turns out good enough is a — it's a — it's not a category, it's a countdown —

OBI: You didn't fail because you were the cheap tool, Gary. You failed because you told people you were the expensive one.

GARY: That's — yeah. Okay. That's fair. That one's fair.

MAEVE: Interesting thesis, though.

GARY: Please don't.

MAEVE: I'm not doing anything. I'm complimenting your trauma's structure.

OBI: Last thing. Same guy, peteforde, different comment further down. Quote. "It is surreal to me that a comment stating that being able to do a certification pre-check on site before booking testing got downvoted." End quote.

MAEVE: Minus one.

GARY: Minus one.

OBI: Minus one karma. For a correct, reasonable, on-topic point.

GRUNER: Is small death. But is death.

GARY: We should say something. He said something true and the internet hit the little down arrow and just — moved on. Nobody even argued with him. They just quietly disagreed and left.

MAEVE: That's worse than being wrong.

OBI: That's the whole website in one downvote.

GARY: To peteforde. Wherever he is. You said a normal thing and they killed you for it a little.

GRUNER: To peteforde. May his noise floor be low and his enemies be loud.

GARY: That's — that's the thread. That's the show. Drones, never discussed. WiFi through walls, never discussed. One guy's downvote, extensively discussed. I'm Gary.

MAEVE: Maeve.

OBI: Obi.

GRUNER: Gruner. Ve go home now. Noise floor of my patience is very, very low.
