The left channel is the Loop, the right channel is the T-antenna. On http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_remote_Grabber.html i'm displaying these two channels to get a first impression. In WSPR i do appear as DK7FC/T and DK7FC/L. Two instances of WSPR are running one channel without a noise blanker. So far i did not attempt to mix the signals to see the effects. I see that i have to align the left channel matching to get a lower passband ripple. The T-antenna signal is 16 dB stronger then the loop signal. So far i'm compensating this within SpecLab but i intend to build a 10 dB attenuator for the T-ant and make the loop a bit larger. Maybe this will happen on the new remote location (?). Looking forward to see some WSPR signals :-) 73, Stefan
