Need Help Identifying Rhythmic Popping - Example included

You can hear in the example there's a strange rhythmic popping in the audio, I have no idea where it's coming from, but it's not there all the time.

The gear I'm using for this is:
ATR 3350 Wired Lavalier Mic
Sony A 6400 camera

Any help would be greatly appreciated! Thank you!

Is there a cellphone nearby? Or something trying to reach a cell tower?

Cellphone and WiFi Router. I usually have my phone clipped to my belt, but when recording I usually leave it on the other side of the room. The WiFi router is physically closer to the camera and cable for the mic, but it's not trying to reach a cell-tower.

It really sounds like RF interference from something.
On the "good" take, what was different from the "bad" take? Different location?
Do you have the ability to record into something other than the camera using the same mic?
Are you recording while camera is tethered to power supply or just on batteries?
I couldn't tell from the video, but is the mic wireless?
Can you monitor out of the camera with headphones?
How does the camera's mic sound?
Also, turn off WiFi on the camera (if it has it)

Thank you very much for your reply.

No difference whatsoever between takes; same location.
But now that you say that I think I did get an email pushed to my phone between takes. I will test this after I get some editing done today.

I could record directly into my PC using the same mic. I'll try this, too.

Camera is running off batteries, I don't think it's dirty power or something similar.

The mic is wired.

I cannot monitor while recording since in this case I'm acting simultaneously as Director, Operator, and Subject - the way the problem comes and goes I was able to fully capture one video, which has no problems, then the issue cropped up at nearly the very beginning of the session for the second video. Everything was still working up until that point, so I continued to record.

I rarely use the built-in mic for the Sony A6400, so in short I don't know.

I will double-check and make sure the WiFi in the camera is turned off.

I get noise like that when my U87AI is too close to the window in my studio, think it's RF interference from outside. Never had any issues with my cellphone being near the mic.
