  We have observed the canonical gigahertz-peaked spectrum source 0108+388 with
the VLBA at a range of frequencies above and below the spectral peak. The
activity that dominates the radio emission from 0108+388, which is also
classified as a Compact Symmetric Object, is thought to be less than 1000 years
old. We present strong evidence that the spectral turnover in 0108+388 results
from free-free absorption by non-uniform gas, possibly in the form of a disk in
the central tens of parsecs.
