Heard Ham-radio sounds

Not sure if this is the right site to report this but today Is when I found your web page after another incident regarding bright lights happened and made me consider reporting them.
This was back in the Summer of July 2021
Aprox 1:05pm
I live at the top of a mountain in rural Green Mountain NC.
While sitting on a bench in-front of my house (facing W) enjoying a nice afternoon, all kind of birds chirping and suddenly out of nowhere I hear
Ham-radio “sounds” right next to me.
(My father is a former Ham-radio amateur, so I recognize the sound.)
I freeze, and slowly move around observing my surroundings yet not seeing any “obvious” object, person, antenna, gadget, nothing!
Sound stops, while I’m “visibly” moving so I return to the bench sat down nonchalantly to see if it happens again….It does, I don’t see anything yet I feel somebody is meticulously watching me.
I don’t believe any of my closest neighbors operate ham-radio’s.
The closest one I’m aware of lives on hwy 80 which is miles away.
Also ruled out the possibility of a bird species that sings like a ham-radio.
That same afternoon, My husband and I went to visit our neighbors and while sitting at front porch she hears the sound and asks out loud;
- “Do you hear that?”
- I reply; - “Oh! Yes, thank God you hear it too because I thought I was going crazy!
- Neither of the husbands hear it.
