[WriteLog] Field Day Classes

[Gary AL9A]

I'm doing some early prep work for this years ARRL Field Day and have 
stumbled across something that I've never seen before.  At the risk of 
displaying my colossal ignorance about this subject, could somebody please 
fill me in on the various Class designation combinations.

I'm looking at some of the downloadable results history files from previous 
Field Day years and notice Classes such as 1B1B, 1B2B, 1B1, 1B2 2B2B, etc. 
I think I understand ones like 3AB, 3AC, etc., but could someone enlighten 
me as to what some of these others mean?
