Hi All,
I found several message on DT and ALL.TXT
I try to analyze ALL.TXT of a couple of months:
awk '{ if ($3=="Rx") printf "% .1f\n", $6+0.0}' ALL.TXT | sort -n | uniq
-c > dt.dat
DT can be '0.0' or '-0.0' by fortran round so the trick '$6+0.0'
the graph dt.png is by gnuplot.
This give me a peek around 0.1 not at 0.2 or more as expected.
See only this data:
57826 -0.1
97438 0.0
572250 0.1
212942 0.2
94977 0.3
My clock is in 5 mS range and is in this range all days by ntp as in
example.png
I have no subtract some mS for the travel at light speed from transmitter.
Cannot understand as the DT is not centered on 0.2 as configured by
default. See also sbTxDelay or txDelay_ variables.
