[Dxspider-support] spot aging

I will try to arrange a test with KC1XX and see if we can reproduce the
problem while watching chanerr.

I do not see how it can be an issue of very late dupes.  The first
occurance of this problem showed at about 0026Z, and Matt's clock is
only about 5 minutes different.  In fact, I just checked and there's
still about 5 minutes difference.

Again, a (really) small file extract...

There had been no other spot of VE9US since 2327Z.  I am stumped as to
where/how it might be a late dupe.  W1HR is fed via a serial link from
K1XX.  When I look at the K1XX dx.dat file, I find:

14250.0    IH9P        27-Oct-2001 
0018Z                                  <K2QMF>
7046.7     VE9US       27-Oct-2001  0021Z  QSX
7211                        <KC1XX>
28592.2    ZK1NCP      27-Oct-2001  0026Z  N.
Cook                          <W9XT>

Note the time of the spot for IH9P from K2QMF.  You can see that this
spot is even older than one from KC1XX and probably closer to 7-8
minutes away from the exact time.  Though not included here in the
extract, the spot from K2QMF is issued on the W1HR node.  

Any other thoughts?

Charlie, k1xx
