Hello Markus,

Thanks for the transmission. A long time ago that i received a ham made 
VLF signal from the east :-)

E field: carrier S/N: 12.63 dB in 195.3 uHz (no decode).
H field (E-W): *carrier S/N: 20.03 dB in 195.3 uHz* | carrier Eb/N0: 5.5 
dB. An easy decode.
H field (N-S): carrier S/N: 0.97 dB in 195.3 uHz

These results are not trimmed to the peak SNR, i just took the basic 
filter/blanker settings.
Mixed antenna results take a bit longer...

Interesting, i did not expect that the E field result is so much worse 
than the H field. But at such high frequencies, the sitation is much 
different than at < 1 kHz ;-) Certainly the reason is QRN from the south 
which is nicely canceled out by the loop.

73, Stefan
