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.

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.

Hi hberg, it could be machine noise from itself.

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