I should have been more specific,
No, I think most of us understood (I know that I did) but the extra detail is fine and since you are doing it, I shall too, at the risk of being ridiculously pedantic.
I was actually not joking around with that answer.
There are no rules. (It is supposed to be lawless, not bound by rules, regulations and conventions, after all.) Stations come and go, change their name(s) on a whim (e.g. Zeeky and Outhouse). Many never give an ID and just want to play some music. I personally don't expect a schedule or a fixed format (e.g., Ball Smacker), but if that's what someone wants to do, that's OK too.
Why was the transmitter on? I don't know. Maybe the guy flipped the transmitter on to show his girlfriend and forgot about it. Maybe he flipped it on to drive around to check the signal in the next state/province over and it took him 12 hours to come home and turn it off. Maybe he was testing his new station operation software and needed 24 hours to do it well. Maybe he left it on because it was a Wednesday night, he felt like getting drunk and fell asleep.
So the fact a signal was heard that bears some resemblance to an entity once known as "Radio Pushka" (and might be called "Radio Mildred's Tattoo and Dog Wash Emporium International" when it resurfaces next week/month/year/decade) is, as you say, notable, but we can also speculate for months about what it was and never find out too. Maybe I'm completely wrong and it was not Radio Pushka. I'm not going to get too hung up on what it was that you heard other than to note what it seemed like to me and that is where I will leave it.
Cheers
