Look on the bright side! Blucifer killed its creator, so no other airport can ever be cursed with this "art".

Denver on a slow day, which is rare, and only for the weird airport lore, gargoyles and also Blucifer, the demon mustang with big ole blue balls and a huge asshole. The trams are really good, but everything else kinda sucks.

I am all for the news about Mars, as long as it has nothing to do with Husk. If that fucker wants to go, he can take his groupies and go. Well, I would also tune into the news if it turned into a pseudo-Last Recall story and some alien artifact collapsed the exploitive oxygen trade.

Doesn't need to be in the same band due to harmonics and power. If you keep splitting the 11m band (CB) into "fractional-frequencies", you are going to get a cross-over somehow, especially if the fundamental is at super-high power.

Using a piano as an example, if you play a C2 at 62.41Hz it still expresses harmonics at C3 (130.81Hz), G3 (196.22Hz) and C4 (261.63Hz) and at least in theory, to infinity and beyond! Each harmonic away from the fundamental will be expressed in decreasing levels of power. (It's like 1/3 power per, I think. The proper math is out there though.)

(sorry to add even more; I just made another comment about this and I am familiar with most of these concepts.)

Actually, that would be much easier. TV stations back then mostly received shows via satellite dish. Pointing a low power directional antenna directly at the dish's LNB would work great. Satellite transmissions weren't strong and were rarely encrypted back then so that would theoretically be super easy if you knew your RF and deep RF knowledge was much more common place +30 years ago.

I am not sure if they used point-to-point microwave antennas back then for TV, but it would be the same concept. (Microwave antennas are typically the round, cylindrical looking, covered antennas we see all over the place today.)

It would require as much, or more, power to drown out a TV broadcast signal at the source. I believe many of the old towers were 200kW-1000kW so it would have taken one hell of a pirate signal if interfering close to the main source. However, RF follows the same principle as light using the inverse square law so the further you get from the primary transmitter, the signal quickly becomes exponentially weaker for any receiver.

If you had a TV transmitter on a small hill that is a fair distance away from the target audience, like many were, splitting the distance with a directional antenna wouldn't require nearly as much power from the pirate signal to overtake the original transmission.

If I wanted, I could interfere with ham radio signals with as little as a watt of power (in my immediate local area) even though people might be communicating through a ham radio repeater that transmits at a couple of thousand watts that is many miles away. (It's actually a permitted emergency technique to "break into" active conversations. Actually, other ham radio operators are familiar with what interference sounds like, even for signals that can't fully overtake a transmission. It's customary to stop the conversation if detected and wait for the "break".)

Right-wing politics basically requires one or more sub-cultutes to demonize. It's hate and blame politics, pure and simple.

As long as the politicians have someone to wag a finger at and blame for all problems, it rallies their supporters. Nazis had the Jews, Republicans have everyone else that they declare different.

Here is the follow-up post on the joke, btw.

Wustite, ferrous oxide, is black. FeO.

Typical rust, usually found as hematite, is Fe2O3 and is red/brown. Also an iron oxide.

Magnetite is also another black iron oxide, Fe3O4.

There are quite a few other flavors of iron and oxygen too.

Dunno about "lost all meaning". The shrapnel from all the butthurt is spraying quite a few instances right now. Lulz.

Just glad to see ml/memes is getting a taste of its own shit for once.
