Youtube video description:
The Yosemite Sam signal is an AM broadcast which has been happening like clockwork since February 2005. It was first reported on December 19, 2004, but went off the air 5 days later and did not start back up until the following February). It is a recording of Yosemite Sam saying: "Varmint, I'm a-gonna b-b-b-bloooow yah t'smithereens!"
The transmission is sent from somewhere in the southwestern desert of the United States, and begins at exactly seven seconds after the top of the hour. It is repeated on 4 different frequencies in ascending order, and exactly 10 seconds pass before the transmission is repeated on the next frequency. The processes is then repeated twice, and therefore takes 2 minutes to complete.
Here are the frequencies:
3700 kHz
4300 kHz
6500 kHz
10500 kHz
The sound clip was apparently taken from the 1949 cartoon Bunker Hill Bunny, and is preceded in the transmission by an 800 millisecond "data burst."
It is believed that the broadcasting station is somewhere near Albuquerque, New Mexico, which is interesting because in many episodes of Merry Melodies Bugs Bunny would become lost and repeat the phrase: "I knew I should have taken that left turn at Albuquerque."

That is freakin great!

i cant help but be a killjoy with that video...makes me kinda sad.

Yes, I received this 75 meter DSB signal back then when I was living in Southern California.
I used the hear the HAMS talk about it and want to get it.... funny
Them CBer types that get their HAM licenses are like that.
the "radio police"
and I thought that they found this beacon to be some US Gov contract employees
inside some secret compound, just playing around.

This was certainly one of the most interesting things that I've ever heard on HF. It really had the DXers and hams in a tizzy, right up there with “She had your dark suit in greasy wash water all year”.
The story that it was a government contractor has been circulating for quite a while; supposedly a couple of hams located the site on some military reservation in New Mexico, and the broadcasts stopped shortly thereafter. However, I've also heard that no one ever really figured it out, and that the "hams found it" story was some sort of myth. Who knows...

Wasn't yer ex working at that place then, Yosemite Al?

Very interesting, thanks Chris!

Actually, I was up that way around 1999. I was using the name "Stayner" back then...

Have heard of Yosemite, but never heard it.
That video is interesting- it said there was embedded data in there. That would lend some credence to the gov't (contractors or otherwise) as this is perhaps a test of embedding data into seemingly innocuous messages. Different freqs for testing propagation of this mode.
Is it still on the air today?

It lasted a few months, Skeez, disappeared for about a year and turned up again for a short time.
It seems to me the last report I saw of it was in either the summer of '08 or '09? It was a one off thing that time around. It makes me wonder if it wasn't someone with a recording of the earlier broadcasts playing around?
I thought you were using the name "Bob Lazar" back then, Al?

I've heard about the Yosemite Sam station before, but that video was a darned entertaining summary of the phenomenon.
