(ARRL 10-Meter Contest, Single-op, CW only, high power from Tennessee)

Presented for what little it's worth...  A couple of times there were little
"bubbles" of rate.  I got really curious as to whether they were the result
of being spotted on packet.  So, after the contest I looked myself up in the
archive on DX Summit.  Found myself 20 times, and put together the following
table:

Time:   time I was spotted
Spotter:who spotted me 
Hr:     QSOs in the hour centered on the spot (0040-0140z for first spot)
10Q:    QSOs/hr for five QSOs preceding and following spot
Post:   QSOs/hr for ten QSOs following spot
Next:   Next five stations worked after spot

Time    Spotter Hr      10Q     Post    Next stations worked

I find it interesting that in six of the 20 cases, my rate actually *dropped*
after being spotted.

Another strange thing...  was that of the 11 spots posted the 13th UTC, in
nine cases I worked the spotter within five QSOs either side of the spot. 
(the exception were both spots by N4GN, who I'd worked S&P 40 minutes before
he spotted me)  Of the nine spots posted the 14th, in only *one* case (AA1K)
did I work the spotter within five QSOs of the spot.  K1TTT, N6EE, and YL2KA
I didn't work at all.  (was YL2KA the op at YL0A?)  

Note the absence of TCG members on the list of spotters - no worries about
packet ethics around here<grin>!
