Wow, I’ve been out a bit, lost a lot ?? !!

Something I noticed today is that in both the 408 and 340, Zodiac used exactly 25 standard alphabet characters out of 26. Which didn’t he use?
In the 408 he doesn’t use ‘C’. In the 340 he chooses not to use ‘Q’.
CQ – Code used by wireless / radio operators. Morse code etc.
I thought maybe the dots and dashes may say something in the 340. Problem is there aren’t that many of them to work with so at best it could maybe read some initials. Or maybe it could just be a hint into his background.I thought it was interesting anyway

I always thought they just mapped to some of the least common clear text letters in english, such as Z, Q, X or J and that would be the reason they are not used in the cipher text.
My Z340 widget for the two-ciphers hypothesis:
But the cipher text characters can be and are anything. I don’t think their plain text conversion matters. Besides he did use both the C and Q, just not at the same time.
What are the chances that by accident he doesn’t use only one of the alphabet characters?
Then the chances that by accident he does the same thing in the next cipher?
And the chance that these 2 characters just happen to spell a form of code sending?
That is a very narrow way to look at it, because you didn’t account for the fact that a lot of other 2 character combinations can indicate many coincidental things.
What other combinations, there’s only C and Q not used?
Zodiac used the regular alphabet and then added extra symbols to go with them. My observation is that he used all regular alphabet characters except one. Then did the exact same thing on the next cipher.
He could have used all the alphabet + symbols. Or n characters of the alphabet + symbols. Or no alphabet and all symbols. But for some reason he chooses to use 25/26 standard alphabet characters then move on to symbols. And does the same thing with both ciphers, which to me makes it interesting.
It could of course be entirely coincidence that he did this, but what are the odds of that. It seems like it must have been a conscious decision to me?
My point is that if he picked a different combination, someone could easily make another connection that *seems* intended.
For example, what if only Z and K were not used? Then you could say he intentionally picked it for "Zodiac Killer."
Or if they happened to match the initials of the victim’s names.
Or abbreviations of the murder locations.
Or connections to hundreds of other facts that could link to the case somehow.
If you are going to try to calculate the odds, you have to consider all the possible connections you’re missing. They can turn up completely at random.
Well yes of course. If he did that then I’m sure it’s quite likely that other connections could be made. Or people would try to.
I think it’s interesting that he did this on both ciphers anyway, without even considering the possible connection to morse code. That just makes it extra interesting that it a actually spells out something related.

Sometimes we want to see something that is not there and start making the facts suitable (alternative facts )
Sometimes there is also a very simple explanation:
Yes that is certainly one possible explanation!
The "solution" was not 100% convincing but I’ve yet to see a more compelling decoding.
Your dad is not the Zodiac.

To me it looks like total garbage, but I did still think the show was fun to watch

Haha, yeah I can see that. WAY better than Graysmith’s nearly unintelligible Herb Caen "solution" though.

I’ve searched to no avail. Is there a link to in-depth analysis and opinions of the show’s cipher methods and conclusions, by doranchak? Appreciate any help.

I don’t support Craig’s solution. My objections were not included in the final product.
In my post about the solution, I linked to several analyses that were already done and are quite thorough:
