Radio and chatter sounds

I read the old discussions about people experiencing different voices like distant telephone chatter, or hearing songs etc. I understand that there are sounds implanted intentionally in the tapes, but my experiences with sounds usually happen after the tapes stop playing.

I’ve head a couple of occasions when once the tape stops playing, I can hear two people talking: can’t hear them very clearly but sounds like (someone here made a good analogy) on an old analog telephone.

Then a few times I could hear what sounded like a radio station with music and DJ. And right now, I just finished one of the Wave 3 tapes and immediately after the tape stopped playing, I can hear a radio station. Since I am still wearing headphones, trying to hear as clearly as I can😁, it’s some kind of rock and roll music station. Listened to a couple of songs that I didn’t recognize (I am also not an expert in rock and roll music), commercials, then DJ started talking. Tried to identify the station but the sound isn’t as loud for me to hear words very clearly. I could hear a few words like Pennsylvania (?… I am in Canada btw), and then he spoke of something happening on Saturday June 27th which is this month in a couple of weeks. Now I am just sitting with my headphones still on because I am still tuned to that radio station.

Anyone had similar experiences?
P.S. I listen to the tapes on an ipad, and when I disconnected the headphones cord from the ipad, the radio stopped playing. I guess that the device is peaking on some radio frequencies?
