Anons. I remember in a very early crumbs Q stated something like the following:
"You wouldn't believe it, but some of these people still use listening posts"
And I looked up what a listening post (think that was the term) was. Basically it's an old communications method from WW1 and WW2 where one radio calls in at a specific time.
This is probably what Ohr and company were doing.
They had specific times they would radio information in, likely in code.
Can anyone find that Q crumb or remember it from early on? I've looked several times.
