Not really, all those numbers relate only to the STRENGTH of the signal at 12 second intervals and they go from 0 to 9 and then from A to Z giving a 36 point scale of strength. Z being highest.
As you can see if you scan across the sheet, mostly you get 1's or 2's, the occasional 3, but there was this signal that went upto a "U", hence the "Wow!" (unless Jerry Ehman thought it was interstellar spam and leet speak for S3xy g1rls").
However, you can see from the numbers that the signal gradually gained in strength and then gradually faded out, which was consistent with an extra-terrestrial signal since the antenna was in a fixed position and was just rotating with the earth, thus the source was fixed against the cosmic background and not in local orbit or a plane or anything like that.
There had been an event like that 10 years before but that time the event reoccured when we looked again. That was the discovery of a brand new phenomenon called Pulsars.
This time though, there was no real explanation (except for the unthinkable).
If you search around enough you will find that most all plausible explanations for the Wow! signal have been exhausted, and you are in the territory of "Space junk at least 250,000 miles out (about the moon's distance) reflecting a signal that originated on earth which just happened to be at the optimum interstellar frequency of 1.42Ghz, which, incedentally is a banned frequency (for anything other than that purpose) for just that reason.". Indeed, it would appear that the most likely explanation is that it really was a message from ET. It just couldn't be proven.
In addition, its determined that the signal lasted no longer than 24 hours since the second antenna, located next to the first did not pick up the signal and the signal was not there the day before. Very weird indeeed but would be explained by the transmitter being turned off or turned away (possibly revolving).
The signal met all the criteria for being confirmation of contact with ET except for one major thing - it was never spotted again.
Although this has relegated it to a footnote of history, it also confirms its "unnatural-ness" as its hard to imagine any natural cosmic occurance that would only send a signal for such a short time and then stop abbruptly.
It is most unfortunate that the tech of the day did not allow for the signal (all 72 seconds of it) to be recorded. Still, that's hardly ET's fault.
Its also worth bearing in mind that when we've sent signals out to the stars (intentional, direction signals) then we do so for only a short time, we send the message then turn off the transmitter (or use it for other things). I've found records of us doing this in 1974, 1999 and 2003 - its not something we do routinely.
All in all, a very suspicious event indeed, and just as much a mystery today as it was at the time.
If anyone has heard of a good (non ET) theory for this event that does not involve "secret USAF spaceships" or moon distance space junk then I'd love to hear it!
It goes without saying that as far as SETI goes, this is by far the best candidate for the real thing there's ever been.
As far as I can tell, in the near 30 years since, no one has actually looked continuously at that spot (in saggittarious) and tuned into the same frequency for more than a period of 14 hours. I believe the major reasons for this is that its located in the Southern Hemishpere and telescope time comes at a premium.
And just for fun, how about a story of an Earth like planet found a couple of months ago in...you guessed it, the constallation of Saggittarious:
