I'm getting '73+55' at Eb/N0 = -0.3dB with
phase pattern 30   60   30   60

Carrier S/N: 15.25 dB in 19.5 uHz

Still working on the first message, noise in the E/W loop
was very high that night.

Looks like we have between 40 and 65 degree day/night phase
shift (depends which antenna I measure it on).
