Hi Stefan,

   Thank you!
My loop used to be two parallel turns of coax, one of the coax cables opened up recently so now it is a single turn loop approx 24m vertical by 44 meters horizontal.

Hi Warren,

Even 4X, that's very remarkable! You are the one with the 2 turn TX loop, right?

Good luck and i hope i will see something too.

Roman RW3ADB reported XGJ last night  on the TF3HZ, 4X1RF, and F1AFJ grabbers at the same time,

LF,

I can see very clear traces of XGJ tonite at TF3HZ, http://simnet.is/halldorgudmunds/TF3HZ_LFgrabber/
Is it the first time? At least i found no capture on the capture archive...
