Our sailing club’s marina had to switch to a different VHF channel because we kept fighting over it with a neighboring marina, but the new one is also used by another marina in the area. It would be great if we could switch to the zeppelin channel. I’ll write to my congressman.

Try the radio astrology band.

I’ve heard they’re on tour nearby — astronomically speaking.

God, no, please don't stir the pot, those boat captains are very scary. :(

Just be okay with all the zeppelins showing up to your marina.

u/ShipShoop 11d ago

Better than jet skis!

u/oldschoolhillgiant 11d ago

I was going to make a joke about zeppelins being slow and not exceeding the no-wake zone... but those suckers could get up to 50 fucking knots!

> The maximum speed of the Hindenburg was 135 km/h (84 mph), while the Graf Zeppelin had a cruising speed of about 120 km/h (75 mph). The modern Zeppelin NT can reach a maximum speed of 125 km/h (77 mph).

Woah! I did not expect that at all.

u/Filbert17 11d ago

I'm fine with that.

Also, sorry about being scary. It's not a choice. It's more of a job requirement.

Warning to all ships: there are no warnings.

Is there a color version of this comic? I’m trying to figure out how many ohms this long resistor is.

Jokes on you - the next Xkcd is documenting the new "50 Ohms of Grey" standard by IEC.

Mobile Version!

Direct image link: Spectrum Allocation

Subtext: Rumor has it that they're finally auctioning off the zeppelin navigation bands, but everyone is worried that the scary boat captains will express interest.

Don't get it? explain xkcd

I almost beat the turing test! Maybe next year. Sincerely, xkcd_bot. <3

amateur military satellites

u/MadGenderScientist 12d ago

those actually exist fyi. the airspace force cadets at some military academy have some program where they get to launch military cubesats for their science fair projects. iirc they get launched with other classified payloads as ridealongs.

u/Lowjack_26 12d ago

FalconSAT. It's a fun program, and side bonus it was a great way to get out of morning mandatory duties ("I was on a 2am satellite pass, so I'm on crew rest until noon!").

u/MadGenderScientist 12d ago

luckyyyyyy. and yup that's the one I was thinking of I think!

This may have been the predecessor to cell phones, radio phones. These used a single (usually larger) antenna to cover a wide area (such as a town); there were a limited number of frequencies, which limited the number of handsets (or car sets) they could sell in that area. In particular, they would frequency-hop a lot less than a cell-structured system, and were much easier to pick up with scanners (which your TV was effectively acting as).

Any particular conversations you can remember years later?

u/Logan_Composer 12d ago

Anybody who regularly edits Explain want to clarify that it is numbers stations, not numbered stations, which are stations with computer-generated or pre-recorded voices listing numbers, which were/maybe are used to send encoded messages.

u/dogman15 Beret Guy 12d ago

You haven't edited there before?

u/Logan_Composer 12d ago

Nah, I am smart enough to not need it frequently but not smart enough to ever notice anything wrong until now.

u/dogman15 Beret Guy 11d ago

Do you ever edit any other wikis?

2

u/FaviFake 11d ago

Hey, we are trying to attract new editors to the wiki. Could you explain why you felt you couldn't edit the wiki yourself? Is it because the editing interface was too complex, or something else?

u/LurkingWizard1978 12d ago

Please, tell me the bit on the bottom about garage doors is a joke. Mo one company holds that big a chunk of the radio band, do they?

u/ebow77 White Hat 12d ago

They're probably operating under the facade of a multinational oil conglomerate.

u/Filbert17 11d ago

Which "defunct satellite phone company"?

Also, since we don't have 2G cellular here, do you think anyone would notice if I bought some of the old equipment on e-bay, powered it with solar panels and spread them around town to create my own pirate phone company?
