30 June heard beacon/alarm tone?

Noob here, trying to figure out what I heard this morning. As ISS passed over, on the FM voice downlink, I heard repeating tones that sounded kinda like "dadadee dadadee dadadee dadadee..."

Is that coming from ISS? Is it something from another ham on Earth that ISS was repeating? At the apex of the pass, it was strong enough to break squelch (Baofeng HT with handheld Yagi-Uda)...

Sorry for the noob question. Just trying to figure this stuff out in my very limited free time...

Fun Time

I left the rig and computer on pretty much for the whole SSTV event and got some pretty good images. More importantly I love events like this I find them exciting and really appreciate the crew taking the time doing these events. Also it's a good reminder the ISS is up there and sometimes passes overhead.

SSTV signal

You're likely hearing the SSTV signal currently being sent on the 145.800 downlink. ISS is sending images.
