I was listening to people making field day contacts yesterday and heard stations saying "Alpha 4" or "Alpha 3" as part of their information.
These were not part of their call signs.
To what do these refer?
Thanks.

It's part of the information exchange that is required to validate a contact
as part of Field Day. Each station must log the contacted station's information.
The first half of the first part is a number, signifying the maximum number
of simultaneously operating transmitters. The second half of the first part
is a letter, signifying the classification:
A = Club or a non-club group of three or more persons set up specifically
for Field Day.
B = A Field Day station set up and operated by no more than two persons.
C = Stations in vehicles capable of operating while in motion and normally operated in this manner.
D = Stations operating from permanent or licensed station locations using commercial power.
E = Stations operating from permanent or licensed station locations using emergency power.
F = An amateur radio station at an established Emergency Operations Center activated by a club or non-club group.
Thus, a station sending "4A" would be a club station (or station with 3 or
more non-club operators), with up to 4 simultaneous transmissions. See
http://www.arrl.org/contests/rules/2008/fd.html for further detail.
The second part is the ARRL/RAC section, as defined at
http://www.arrl.org/contests/sections.abv.html.
