I have used the Climate Notebook software to analyze and archive
data obtained using the Hanwell system and it was an extraordinarily
tedious task that I hope to not have to repeat.  I am a huge fan of
the Climate Notebook software and have used it with no trouble in
conjunction with several other loggers.

I received frequent error messages every time I tried to import the
Hanwell data.  We eventually realized that this happened every time
the Hanwell receiver did not successfully register a signal, which
occurs infrequently with some sensors and, at our institution more
frequently with other locations.  It registered a N/A which could
not be read by the CNB.  It may be that this problem can be
corrected by the excellent CNB programmer but I had to scroll
through each Hanwell file to delete all N/A entries, which was very
time consuming.
