The precise location in the sky where the signal apparently originated is uncertain due to the design of the Big Ear telescope, which featured two feed horns, each receiving a beam from slightly different directions, while following Earth's rotation. The Wow! signal was detected in one beam but not in the other, and the data was processed in such a way that it is impossible to determine which of the two horns received the signal.[15] There are, therefore, two possible right ascension (RA) values for the location of the signal (expressed below in terms of the two main reference systems):[16]

From Midway portraying the attack on Pearl Harbor:

Halsey glances at CAPTAIN MILES BROWNING, his operations and war plans officer.

HALSEY

Pearl found something?

CAPTAIN BROWNING

Yes, sir. Intelligence managed to get a radio fix on the attacking fleet. Unfortunately, it's a bilateral reading. Meaning the Japs are either at 363 degrees...

Browning points down at the map table, his finger tracing a line due north of Pearl Harbor on the chart.

CAPTAIN BROWNING (CONT'D)

...or 163 degrees.

Browning traces a second line heading due south. Halsey's face wrinkles in disgust.

HALSEY

For Christ sake... Pearl is under attack, and we don't even know if the bastards are north or south?

You never think that having a radio system with directional ambiguity built in will matter much until all of a sudden, you receive a single instance of a signal when you really really want to know where it's coming from, and desperately wish that you'd spent the extra to not have that limitation.

Ehman said in 1994: "We should have seen it again when we looked for it 50 times. Something suggests it was an Earth-sourced signal that simply got reflected off a piece of space debris. He later somewhat recanted his skepticism, after further research showed the unrealistic requirements that a space-borne reflector would need to have to produce the observed signal. The signal's frequency of 1420 MHz is also part of a protected spectrum, a frequency range reserved for astronomical research in which terrestrial transmissions are forbidden, although a 2010 study documented several instances of terrestrial sources either interfering from adjacent frequency bands or illegally transmitting within the spectrum

I'd be curious to hear latest theory upon such!

In my head canon for the Men in Black film, this was a signal sent to Elvis (who died the next day).

"Elvis is not dead. He just went home."

Is this where the Zoomers are getting their "6 7" meme? I still do not understand that meme.
