Very strong at Bielefeld (Wolf Buescher, vlf6, 303.8km) Eb/N0 11.6dB, 27.17 dB in 11.8 uHz, -56.1dB in 2.5kHz, constant reference phase. Here, improved my decode to 3.9dB when I remembered to use the -a option which normalises the amplitude by the average noise. I am not seeing much day/night phase shift at any site. Some measurements on the carrier will be the next job. -- Paul Nicholson --
