Dan - unfortunately not, at least from my understanding of the actual paper. I think the confusion comes from the Very Large Array (VLA) and the VLBA (Very Large Baseline Array) which does have a dish on Mauna Kea, both being run by the NRAO. The paper suggests the observations came from the VLA alone (I might be wrong). The paper mentions VLBI (very long baseline interferometry). Interferometry is what both the VLA and VLBA do, but think it refers to the VLA being used with its longest baseline. The VLA is in New Mexico.
