“LWA” (without the “1″) is a proposed long-baseline aperture synthesis instrument that would consist of 53 stations similar to LWA1, plus a correlator.  For details, see Ellingson et al. (2009), “The Long Wavelength Array,” Proc. IEEE, 97, 1421.  Although UNM holds the lease to several sites that would be suitable for the next few stations of the LWA, there is currently no funding available for these stations.
