there is something strange here...
My channel 1B suddenly sparked with a noise floor of 400+ mVpp
When i set threshold to 555 it stopped and calmed down again.. so now its @ 61-23mVpp
I unplugged my Alarm, still i got the high Noise. so i took donw H-Field for "service"....
*edit* Now im running only E-Field.
(here is the trouble about reading around, because E-Field shall be AMP2, but I have also read that if you use one antenna, it should ALWAYS be amp1) -still for test/faultdebug it should not be a problem..
I have tried E-Field @ both amps, to see if i get the noise on Amp1, but none of the amps gives the noise when using E-Field. (still i might have been "lucky" to try while the noise was not present.
and about 10 hours later, there has been no spikes on my E-Field.

I started with low threshold and my E-Field was ticking away in sync (with a few sec delay) with signals on the eastern side of USA..
If im making a crude test Antenna, Coax loop is the easiest one, but if im not using transformer, should i not add a resistor? what value? (or am i remembering wrong now? )
