Just to qualify what I mean by high run rates:

The best 60 minute rate was 217/hour from 1349 to 1448
The best 30 minute rate was 228/hour from 1358 to 1427
The best 10 minute rate was 246/hour from 1418 to 1427

The best 1 minute rates were:
 6 QSOs/minute    7 times.
 5 QSOs/minute   32 times.
 4 QSOs/minute  122 times.
 3 QSOs/minute  238 times.
 2 QSOs/minute  328 times.
 1 QSOs/minute  425 times.

The 1.8k is a nice tool when working a weak DX station who is running the
pileup.  It is very poor if you're the one who is running and attempting to
work callers at high rates (i.e. getting the call correctly the first time
without repeats).  I'll be selling my 1.8k in favor of a 2.1k after my
recent experience.

73,  Bill
