  Using the Very Large Array (VLA), we observed all three of the 6-cm lines of
the doublet Pi 1/2, J=1/2 state of OH with sub-arcsecond resolution (about 0.4
arcsec) in W49A. While the spatial distribution and the range in velocities of
the 6-cm lines are similar to those of the ground state (18-cm) OH lines, a
large fraction of the total emission in all three 6-cm lines has large
linewidths (about 5 -- 10 km/s) and is spatially-extended, very unlike typical
ground state OH masers which typically are point-like at VLA resolutions and
have linewidths less than 1 km/s. We find brightness temperatures of 5900 K,
4700 K, and greater than 730 K for the 4660-MHz, 4750-MHz, and 4765-MHz lines,
respectively. We conclude that these are indeed maser lines. However, the gains
are about 0.3, again very unlike the 18-cm lines which have gains greater than
10000. We compare the excited state OH emission with that from other molecules
observed with comparable angular resolution to estimate physical conditions in
the regions emitting the peculiar, low-gain maser lines. We also comment on the
relationship with the 18-cm masers
