Getting reliable decodes at Bielefeld.=C2=A0 =C2=A0Cumiana not timing the signal very well, many thousand timing breaks each day

For unknown reason a poor S/N at Warsaw 20/21st.

Stacking 18/19th + 19/20th produces a false decode at +1.6 dB,
beating the correct decode at +0.5 dB.=C2=A0 Pure bad luck there.

Phase shifts from 18/19th to 19/20th:

=C2=A0Todmorden:=C2=A0 -44.4
=C2=A0Bielefeld:=C2=A0 -54.7
=C2=A0Warsaw:=C2=A0 =C2=A0 =C2=A0 +8.4

Phase shifts from 19/20th to 20/21st:

=C2=A0Todmorden: -129.0
=C2=A0Bielefeld: -137.3

Still something is changing the phase from one night to the next.
