In this case . JA is real , but only
1 station detect the signal , but
as only 1 report , tagged ''??''
This
is the disputed time . the 4 mins
is not a timed event , its determined
by varying factors ,
in this case two
spots at 0034 would indicate a
genuine spot , last night some showed 5
mins lag

In this case
, LA3EQ is spotted by 2 op decodes ,
with 5 min lag for DY, could be +/-
59 seconds inside the 1 min step as
well .. spot passed by quality check
