@@cam862official I know they’re all analog for sure cause they all have the original controls. And I’m almost positive they’re all dual tone considering the ones we do know are dual. There’s also a dual tone 2nd Gen 4004 up by the university
@@AWT5020 welp, turns out they weren’t all analog after all. another siren youtuber who lives in this area recently recorded the gen 1 unit at 111th and Yale and it was a digital 465hz 864
@@AWT5020 I asked emergency manager Joe Kralicek about it and he said that his guess was that the drivers on the sirens are no longer in production and so we are using different parts to repair them as they wear down and the parts may have slightly different variations that you are picking up
@@jonathanboyd9644 The drivers have nothing to do with the pitch of the siren. That had to have gone in the controls at some point and programmed it to dual tone
@@jonathanboyd9644 Hmm. You sure it was this one? At 91st and Harvard? I believe you, just making sure it’s the same unit. If so they might’ve changed it to be dual tone for whatever reason
It almost sounds like a Thunderbolt and a dual tone modulator! It sounds really cool!
Hey another high pitched dual tone! Nice! I’ve heard the Ohio dual tone whelen
Nice I used to live in Tulsa but moved
When did you move?
@ I moved last year
@ where did you move to?
@@jonathanboyd9644 Bartlesville Oklahoma
Nice! I just recorded a single-tone and dual-tone in tulsa!
It sound like a federal signal eows control box that's why he needs the same brand like whelen
Epic!!! Is this the one located near tulsa northeast community campus?
@@cam862official It is not, this one is at 91st and Harvard just east of Jenks
@ so this one is located at jenks northeast elementary then. right?
@@cam862official Yep
That high pitched undertone vaguely sounds like a 2001.
How many analog units do we have in the tulsa metro area?
There’s a handful. All of the 1st Gen 4004s there are analog as far as I know. Plus a few 2nd Gen 4004s are also analog

@@cam862official I see that now. Interesting. I guess me and that other guy will have to record all of them over time

It sounds like it’s from Columbus, Ohio. Right?
@@Jake-w3l Yeah. Columbus has some analog Whelens
it sounds exactly like Westerville Ohio’s dual tone unit.
Did anyone record the siren at the TCC Northeast Campus?
@@jonathanboyd9644 I didn’t, not sure about the other people that live in that area
@ Why didn’t you record the siren at TCC Northeast Campus?
@@jonathanboyd9644 I have other plans this month. Might get back to Tulsa in January or so
@ Someone else said they would but I don’t remember who it was. Do you know who it was?
@@jonathanboyd9644I am this Wednesday since the sky’s are clear, Elijah Hamilton might meet up with me too.
I thought it was a single tone analog. And now it’s dual tone? Right?
@@Jake-w3l Apparently it was. I had no idea though
It used to be single tone, I don’t know why it got changed to dual tone.
@@jonathanboyd9644 They likely changed it so it could be heard from farther away. It’ll be more distinguishable than single tome

This used to be a single tone analog. What happened?
@@jonathanboyd9644 Since when? I only know of 1 other video of this siren heard and it was from a tornado warning. It was dual tone in that too
First time I heard it being a single tone analog was in 2005. And the last time I heard it was in 2010.

Very unusual wind up. Almost sounds like Wail.
@@sirenfan97 Yeah. I think all of the analogs in Tulsa are like that
ThunderWhelen 😂
@ what do you mean?
@ it literally sounds like a modulator ThunderMod… hence, the name
