PS: It could be interesting to see the QSB between LOOP and T-ANT in
QRSS-3, rather then just the SNR in WSPR. I need your signals :-)

Hi all,
Now my stereo RX is running the first time. 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
