New Mexico Tech set up a two-element array with a couple of rebuilt K-band satellite-television dishes.
I don't know what they used for the correlator.
The Array Operations Center for the EVLA (Very Large Array) and the VLBA (Very Long-Baseline Array) are on the New Mexico Tech campus; we had a lot of radio-interferometer people in town.
