Hello,

i've tested the EMF-390 in my small emf chamber, and while nearly all frequencies are blocked, it seems there is still something showing on the emf browser:


It is not affected beeing inside or outside the chamber.

What is that? Thanks.

I see exactly the same peak with my unit. I suspect this is coming from the unit internally.

Yes it shows on most devices looks like.

Hi EmfDev,

does it show up on your device?
EmfDev Posted - 11/18/2024 : 11:41:13
Hi hberg, it could be machine noise from itself.

Hi,

tested the device at different places, in the car, outside the car, the 424 MHz signal is always there without change of power.
This looks like the device is faulty.
