=10BABYA=:
? I have been puzzling over this for a while. It might be an end point to stop reading.
tl;dr: I think the real key is to correctly interpret 0=0A=10BABYA=36WOWÐS and z69JZqlJn862D1ndx7oLVEMmVOlP1zewEeUCrsI7Roahzpeny7P .
I'm still not quite sure what to use it on, but I'm pretty sure the 0=0A=10BABYA=36 is a character mapping.
0=0
A=10
BabyA=36. Morse code has no lowercase, so she called the lowercase 'a' BabyA.
This also jives with the background story for Wow!.jpg. The numbers/letters are intensities:
The circled alphanumeric code 6EQUJ5 describes the intensity variation of the signal. A space denotes an intensity between 0 and 1, the numbers 1 to 9 denote the correspondingly numbered intensities (from 1.0 to 10.0), and intensities of 10.0 and above are denoted by a letter ('A' corresponds to intensities between 10.0 and 11.0, 'B' to 11.0 to 12.0, etc.). The value 'U' (an intensity between 30.0 and 31.0) was the highest detected by the radio telescope; on a linear scale it was over 30 times louder than normal deep space.
Edit:The code from Wow.jpg (z69JZqlJn862D1ndx7oLVEMmVolP1zewEeUCrsI7Roahzpeny7P) maps to the following numbers using the above character mapping:
61 6 9 19 35 52 47 19 49 8 6 2 13 1 49 39 59 7 50 21 31 14 22 48 31 50 47 25 1 61 40 58 14 40 30 12 53 54 18 7 27 50 36 43 61 51 40 49 60 7 25
