The rules don't specify the amount of band changes so you can change bands
as much and as often you like.
>From the rules (General Rules for Contests Below 30 MHz):
2.3.1. Multioperator, Single Transmitter: Stations are allowed only one
transmitted signal at any given time.
22.214.171.124. Limited to 6 band changes (maximum) in any clock hour.
126.96.36.199.1. The clock hour is from zero through 59 minutes.
188.8.131.52.2. Band changes are defined so that, for example, a change from
20 meters to 40 meters and then back to 20 meters constitutes two band
Originally the rule required a M/S to remain on a band for 10 minutes, as
in CQWW. This did not make for much fun if you went to 10 meters to work
your LU multiplier, and then could not work stations elsewhere for 9 minutes.
Some years back it was changed to eliminate the ten minute requirement and
allow you to QSY to a different band after working that 10 meter LU. You
just can only do three round trips in each clock hour.
Since you can't transmit on a second radio, a "multiplier station" is
pretty much a useless concept in ARRL DX. A second station is still useful for
filling band maps, making quick band changes, and working those three extra
multipliers per hour.
