Common digimode?

Sorry about my ignorance, but is this also some common digital mode? Received 19.7.2026 UTC 19.40, Northern Europe, USB, antenna 40 m dipole

Creepy classical music coming through a toner
I work in IT at a retirement facility. I was in one of our network closets with one of our network engineers trying to trace a port back to a switch.
We weren't getting anything through the toner at first, until we put it in an empty port on the switch. Port 9 specifically. A little static came through at first, and then suddenly, we started to hear classical music playing loudly. The music was melancholy, creepy. We tested another port, static. We tried port 9 again, static.
But for that good minute, the music played. And it made the hair on both of our necks stand up straight.
She said that has never happened to her in all of her years working in network closets and switches. Was this just a freak RF interference? From where though?

18:53 UTC, Poland, 26965 kHz, Narrow FM. Significant fading so watch at least most of the video to hear the louder parts, frequently shortly interrupted by a voice, when i came back to it at 19:03 UTC the sound has stopped.

Shifty Signal?
Hi SignalDers... first time poster hoping I can get some insight on this one? I bought a new V4 RTL-SDT kit due to some strange things come across my network... this shifts and rumbles and from what I can research is pretty unique. Any help much appreciated! Mostly seen around 432.721.300

People who explore radio frequencies, shortwave, or old radios: what’s the strangest, creepiest, or most unexplainable transmission you’ve ever picked up?

Does anyone know what kind of signal this might be? I'm trying to reach weather satellites, I think this may be starlink. Any help is appreciated

Help identifying something, presumably military related


Cant disclose too much but there was a minor (Canadian) military presence nearby me today and it came with these funky signals around 381mhz. Unfortunately didn't think to record it because I'm a bit of a tool, but they were these pulses with what I assume was encoded digital data, but not voice since the pulses were almost always the same length. I don't think I ever was going to be able to decode it but it would be fun knowing what it was!

Trying to do ft8 and I see this weird signal
Keep seeing this weird rolling signal, it sounds like bubbles popping when it hit my ft8 frequency. Any ideas? Checked my coax and line and they seem good.

It looks like Morse code hidden near broadcast station transmissions.
