Hi Stefan,
The reference is tuned into ICV on 20.270 KHz. It looks like that 3rd PC that I test now is the best of 3 sofar. But it runs to 
short to see details.
The TX PC is connected to a passive loop. Not to the Mini Whip. ICV is stable here at that loop and not much effect at the signal 
during sunrise and sunset.
GQD and GBZ fade out totaly at sunset/sunrise. ICV does'nt.

I must say all 4 grabber windows at my Grabber website are locked at 22k1.

The localy generated signal in that 47uHz window at my grabber looks good. I'm tuning the power a bit to get just over the noise.
That's why it fades in and out :-)

(if you just tuned in, I'm only local testing with few 100mW into 12 cm pice of wire :-)

I leave the building  now,  I leave it as it is for now.

Btw, I think to see traces of civilization on 8970.00 Hertz.

73's, Peter PA1SDB

  Hi Peter,

  Which reference signal are you currently using? I think GBZ and GQD should be optimal for you. I'm using GQD for my 2nd VLF 
grabber in the moment.

    Tnx Stefan,
    My 3rd experiment, a 10 year old notebook, ASUS PC has just (10h UTC) begun generating a trace at 8970.1 Herz. Lets see what 
happens in the next hours.
    I will buy such soundcard as you sugest for USB port if this 3rd PC fail's to...

    CU.
