Weird interference . . . from Sony cameras?

[KB2GOM]

Early this am I sat down to poke through the menus on my two Sony superzoom cameras to make sure I understood the video settings.

Before I fired up the cameras, I switched on my 396T to scan common military aviation freqs and my 125AT to monitor civilian and military guard frequencies.

I start messing with a camera and both scanners light up, locking onto emergency frequencies, emitting a loud hiss but no voice. I switch on my SDS200, point it at military and aviation frequencies, and it locks onto "Haircut" (331.000?) again with a hiss but no audio.

Finishing with one camera, I switch it off. The hiss goes away on all three scanners, but I don't notice the correlation until I switch on the other camera, and the hiss comes back. I check both cameras: wi-fi, gps, and bluetooth are all switched off. Nevertheless, switch on either camera, the hiss comes back; switch the cameras off, the hiss goes away.

What, specifically, could be generating the radio interference?

Are they wifi enabled cameras?

Electronics can definitely interfere with them. I've had a chromebook do the same thing to my BCD325P2 in the past but only when it's within a certain distance and only when the chromebook is streaming a video (YouTube, Vimeo, etc). So the wifi signal, or some internal component working in conjunction with it, causes the issue.

WiFi, bluetooth, and gps were all switched off.

Sounds like they are not RF Shielded around the CPU board.

Had wireless cameras do it to me too.

What, specifically, could be generating the radio interference?

Most likely a clock signal, of which there will be multiple. (CCD, data bus, CPU, display, etc...)

Yep. I had one that did this too. About 225 if I remember. No CTCSS of 67.0 Nothing but a hiss. But one wonders, can someone with a video scanner lock onto that frequency and "SEE" what the camera sees... Seriously. I found a dead carrier from a DVD drive of 406 from an XBOX. Something in there is acting like an antenna and spitting that out.
