“Peter Jackson would edit it down to a tight 16 hours.” (15:34)
Questions
Where do "10-4" and "Roger" (for "understood") come from? (01:05)
Our guess
Military or police radio codes from World War II, with "Roger" from Morse code's "R" for received.
Military or police radio codes from World War II, with "Roger" from Morse code's "R" for received.
Reveal the answer
The answer
"10-4" is one of the 10-codes created by the Illinois State Police's communications director Charles Hopper between 1937 and 1940 for police radio. "Roger" is from the WWII phonetic alphabet for R ("received"), which came from the Morse habit of replying with the letter R.

[00:00] Speaking of getting news from fake sources, do you guys want to do an undegoogleable? [00:05] Sure. [00:06] Can we do an undegoogleables? [00:19] That was the play of it. [00:21] Super excited. [00:22] You told us we had to, sir. [00:24] You said we signed up for it. [00:27] In the end, it's going to be better and more true than Google can give you. [00:33] Jason, I think it's time for an undegoogleable. [00:37] What do you got for us this week? How can I help you? [00:42] I mean, you have helped me so many ways throughout my life, [00:46] and the fact that you're willing to help me more is so appreciated. [00:50] Okay, here's one for you. [00:52] So, you hear in the movies a lot, or on, I guess basically the movies. [00:57] It's the only place I hear it. [00:59] People are talking on the walkie-talkies, or the CBs, [01:02] and they're saying like, 10-4. [01:05] Gotcha. [01:06] Or Roger means the same thing, basically. [01:09] Like, heard. [01:13] In other parlance, people say over or over and out, [01:17] and that seems much more direct to me than Roger or 10-4, which are... [01:23] Roger, Roger. [01:25] What's with Victor, Victor? [01:27] What's with Victor, Victor? [01:32] You guys have any ideas on what? [01:37] Well, I mean, so 10-4 just seemed like just off a list of codes, [01:42] like for truckers or, you know... [01:44] Ah, it feels military to me. [01:46] Or maybe, yeah, or military. [01:48] But it just seemed like it was a list of codes that you would just say [01:52] for different, you know, just whatever. [01:56] Confirmation, or, you know... [01:59] But why would you want a code for heard? [02:03] Right. [02:05] Because you're like military, and you need code for everything. [02:07] I guess, yeah. [02:08] And yeah, so you don't want people tapping your conversation or whatever? [02:11] I mean, it's not that... [02:13] It's not like it's a brilliant cipher. [02:21] What are the 10th and the 4th letters of the alphabet? [02:26] Well, D is the 4th. [02:28] Yeah. [02:29] So it's not like, okay, or something like that. [02:32] Right. [02:33] It's a simple substitution, but maybe it's a... [02:38] Yeah, 10 is J, so yeah, not very helpful at all. [02:41] JD. [02:42] Lawyer's in the house. [02:44] JD. [02:47] And then Roger. [02:48] Roger has to be like an alternate of right or... [02:54] I don't know. [02:55] Like... [02:56] What's in the... [02:59] What's in the... [03:01] Not the phonetic. [03:02] Yeah, like the NATO phonetic. [03:03] It's Romeo. [03:04] NATO phonetic, yeah. [03:05] What's R is for repossess or something? [03:10] It's Romeo. [03:13] Romeo. [03:14] But maybe pre-NATO, it was Roger, because that's way more American than Romeo. [03:20] Rem. [03:24] That's true. [03:25] So maybe, but still, then why R? [03:28] Why is R like... [03:30] Got it. [03:31] Got it. [03:32] Maybe there was a guy who just always understood what was going on in the video. [03:41] And his name was Roger. [03:42] And his name was Roger. [03:43] But we're thinking these are all... [03:47] I mean, yeah, it seems very obvious that most of these are military-derived, right? [03:52] I always think that. [03:55] Because they're going to be at the forefront of communication like this, where it's out [04:00] in the field and crackly, staticky radios, and you need to be as clear as possible in [04:07] your communication. [04:09] And I'm like, police as well. [04:11] Sure. [04:12] But I don't know if that's... [04:13] I guess I would think that those technologies are going to come to the military first. [04:19] Yeah, I just assumed that police are all former military. [04:22] Right. [04:23] I mean, that's how the stuff seems to work. [04:26] Your riot gear starts in the military, and then it trickles down to your local police [04:31] forces, the tanks and stuff. [04:34] I mean, that's just logical. [04:36] That's just the way you would want to secure a neighborhood. [04:41] Right. [04:42] Well, so we're assuming that these things are all radio and not byproducts of like [04:49] Morse code or something. [04:51] Oh, that's a good point. [04:52] Yeah. [04:55] 10 seems like a lot of times to hate. [04:57] 10 seems like a lot of hashes. [04:59] Yeah. [05:00] I feel like with the Morse code, though, I feel like there's... [05:05] It's what's going to be much more clear. [05:14] He said what? [05:20] Every response is longer than the original message. [05:23] Right. [05:24] Excellent. [05:27] I feel like with Morse code, though, it's the written word. [05:33] It's not going to be as confusing. [05:36] I feel like assuming that their error rates are low, I guess... [05:43] Probably. [05:44] But I'm sure they still punctuated the end of a message somehow. [05:48] Sure. [05:49] Yeah. [05:50] Just like with the telegram, you would say stop or whatever. [05:54] Yeah. [05:55] And then you would want some sort of way to relay back to the person on the [06:04] other end like received your whole thing. [06:08] Maybe that's what Roger is, is received. [06:10] Yeah. [06:12] I'm guessing so. [06:13] Good call. [06:16] And... [06:19] All right. [06:20] Good. [06:21] I'm glad we worked that out. [06:22] Yeah. [06:23] I like that one. [06:24] Yeah. [06:25] I guess at least the 10-4, I feel like that that was probably part of a larger list of [06:30] common responses for a little disambiguation. [06:35] And so time-wise, we're thinking this is post-radio, post-transistor, so the 50s were [06:45] starting to do this stuff? [06:48] 40s? [06:49] Yeah. [06:50] Probably World War II, I would have thought. [06:54] Yeah. [06:55] That's what I'm thinking. [06:56] But I mean, I feel like they had good reviews and... [07:00] Well, they had Morse code and telegraph before that, right? [07:04] Yeah. [07:05] Yeah. [07:08] But I feel like they're definitely rocking all of those technologies during World War II. [07:14] Okay. [07:15] But definitely like 20th century, early to mid-20th century. [07:19] Yes. [07:20] Okay. [07:21] Yeah. [07:22] Okay. [07:23] Okay. [07:25] And strictly American? [07:27] Good question. [07:31] Doesn't Roger mean something filthy in British? [07:35] Yes. [07:36] So probably not British. [07:38] It's what Coalson hopes he's doing. [07:44] But probably not. [07:45] But probably not. [07:46] Okay. [07:50] Let's see. [07:51] 10-4 is one of the so-called 10-codes or radio signals invented by the Association of Public [07:59] Safety Communications Officials International. [08:04] It is an affirmative signal, it means okay. [08:08] The 10-codes are credited to the Illinois State Police Communication Director, Charles [08:13] Hopper, who created them between 1937 and 1940 for using radio communication among cops. [08:22] Nailed it, Joey. [08:24] And we got the timeframe. [08:25] Well, that seems pretty straightforward. [08:28] The early thing that I'm getting on Roger is that Roger was phonetic for R, received [08:33] and understood. [08:34] Okay. [08:35] Cool. [08:36] Okay. [08:37] So here's Popular Mechanics, which is probably a little bit more trustworthy. [08:41] The use of Roger as a confirmation has roots that go back even further than 1957. [08:49] Let's see. [08:51] Roger comes from a phonetic alphabet used by military and aviation personnel during World [08:54] War II. [08:55] So same deal. [08:57] In the Morse code days when sending long messages should be arduous, a useful shorthand was [09:02] to respond with single meaningful letters. [09:07] So responding to a message with letter R, for example, simply let the sender know the message [09:11] had been received. [09:14] When two-way radio came along, the shorthand continued, but with the word Roger instead [09:18] of R itself. [09:21] So back on the 10-4, when the technology was first being rolled out, there were limited [09:30] channels. [09:32] So they had to make their communications quick where other people wouldn't be able to use [09:39] it. [09:40] So they were using these codes just to communicate quicker. [09:46] Yeah. [09:49] So interestingly, 10-1 meant you are being received poorly. [09:58] And 10-2 is the equivalent of Roger, I guess, which is you are being received clearly. [10:07] And then 10-4 is understood, or I actually got it. [10:11] 10-3 shut up. [10:13] Yeah, exactly. [10:15] Stop transmitting. [10:16] So I like this one. [10:18] So on Wikipedia, the 10 codes, the first one on the list is 10-max. [10:24] And it means somebody is AWOL or a corrupt officer. [10:28] Officers are not following orders. [10:31] In subordination slash rogue officer. [10:35] Seems like a wide range of responses would be elicited. [10:41] For instance, 10-35 is alcohol violation. [10:45] 10-34, riot. [10:51] So the thing is, OK, so there is a 10-35 before 10-34, but I don't know. [10:59] There's different. [11:02] So the 10 codes, there's different standards, it looks like. [11:07] So there's like the first ones in 1937, 39. [11:11] Yeah, and there's just like, there's different, over time, there's different standards. [11:19] But yeah, I've seen a lot of these. [11:25] Like 10-91, prepare for inspection at this date and time. [11:31] 10-83, half officer, somebody called the station by telephone. [11:37] And then for some things, they like have subcategories like, so 10-91 can mean prepare for inspection. [11:48] Or it can also mean, if you add a letter after it, animal in some state. [11:55] For instance, a 10-91E is an animal bit somebody. [12:01] So because they're apparently quickly became regional and jurisdictional differences, it [12:08] really wasn't until Hurricane Katrina that 9-11 has gone away from these 10 codes and [12:15] moved to just plain talk. [12:17] So instead of yelling out, for instance, 10-36, 10-36, you just ask what time it was. [12:24] OK, gotcha. [12:28] Because 10-36, if you're like communicating with somebody from some other jurisdiction, [12:33] meant like... [12:34] I'm being murdered. [12:36] Yeah, exactly. [12:37] Animal with a gun. [12:41] That's 10-01 in Boise, by the way. [12:47] That's just like status quo in Boise. [12:52] So these are the same idea as what we've also, you know, you've seen some of these before, [13:01] but the penal codes used by different jurisdictions, like California, you know, well, 187 is for [13:08] homicide. [13:12] I think 420 might be something. [13:14] 420 might be something, 311 is one of them. [13:18] It was like for, I think the band was from, no, it was like public indecency or something [13:30] because I think one of them was streaking or something. [13:32] I think it was, they were from like Kansas or something like that, or Missouri or somewhere. [13:41] All right. [13:42] Cool. [13:43] Thanks, dudes. [13:44] Nailed it. [13:45] Nailed it. [13:46] Obviously. [13:47] What was that guy's name? [13:52] Dennis Hopper. [13:53] No, that wasn't right. [13:54] Isaiah Stewart. [13:55] Where'd it go? [14:01] Charles Hopper. [14:03] Charles Hopper. [14:04] What did the Hopper? [14:08] Apparently 10-04 is like, or October 4th is the day to salute radio operators. [14:13] Aha. [14:14] Very nice. [14:16] Of course, did also, those caught on in the CB community too. [14:23] Certainly hearing a trucker say 10-4 was always, it was always at least in the movies. [14:28] 10-4, good buddy. [14:29] 10-4, good buddy. [14:33] It feels natural when you say it, Hopper. [14:35] Yeah. [14:36] If they don't say that, I'll be sorely disappointed. [14:41] They still use those in the long haul. [14:46] Are they all on, do you think everybody's on TikTok now? [14:51] They're just on a Waze. [14:55] Do you think they communicate by dance now? [14:57] I hope so. [15:00] It's all interpretive dance. [15:02] That's right. [15:03] Yes. [15:04] That's the way everything's going. [15:06] We'll send Coalson to a truck stop for some. [15:09] We'll send Coalson to a dance class, I think. [15:11] Yeah. [15:12] We'll send him to a truck stop to investigate in the middle of the night. [15:14] See how that goes. [15:17] Do some interpretive dance. [15:18] See how it catches on. [15:19] See how it goes for him. [15:23] Put that on Facebook live. [15:30] We should slap a GoPro to him and just, I just want to do like a day in the life. [15:34] Wind him up and let him go. [15:36] Yeah, exactly. [15:37] I'd pay good money for that. [15:41] Can we get Peter Jackson on this project? [15:45] I think so. [15:47] He's all over this project. [15:51] Yeah. [15:52] Peter Jackson would edit down to a mere 16 hours. [15:57] To a tight 16. [15:58] Tight 16.
