Thanks useful information: 5
Hi all.
It has been a long time since I have been active on here...
What I am looking for is some advice on a camera (point and shoot or DSLR) which is low RFI and which I can use close to a sensitive radio receiver for taking photos and videos of what it is receiving.
Paul
Hi Paul, I rather fear that most readers here have NFI about RFI. I at least know what it is, as will a few others with a technical or engineering background, but have no clue as to which camera would be best (other than a mechanical film camera, of course). Your best bet is to ask on DPR. They are total gear-heads over there, and some members have a remarkable fund of knowledge in specialised areas.
Just to add to what Tony has written above, here is a screen capture from my Canon 5D Mk IV User Manual that provides details on how it satisfies certain FCC Requirements.
I assume that this would be with Bluetooth, Wi-Fi and GPS turned off?
I expect other camera manufacturers would provide similar details.
Cheers
Dennis

OK, so who want to be first to expand "RFI" - or "NFI"?
Some might be VG, and even say TAL (FT) - that is.
Else we may hang our heads morosely and think TFN

CC, Image editing OK.
Radio Frequency Interference
No Flamin' Idea?
TFT, Nardes.
So that's what Paul was talking about! Of course
Well, I must say, some of us had NFI.
NFI which camera has lowest RFI but more than that, I had NFI that it was even possible to see what a radio receiver is receiving
You can connect a radio receiver to a monitor via a modem, think old school dial up days, and the radio signal can then turned into visual data.
The need for the low RFI camera is to prevent anomalies in the output data that are caused by interference from the camera and other external sources of RFI
So I guess he would be photographing that output data rather than the raw radio input data

In the old days, you'd use an oscilloscope. Possibly you still do.

Here is a photo of the radio I am using:

What I am trying to do is take photos and videos of what I am receiving (both the display and also the audio). As I am hunting down very weak signals, what I have been trying to use causes interference and blocks the weak signals.
Can you put the camera in a Faraday Cage?
Cheers
