Interstellar communication signals have been conjectured to be present, albeit difficult to identify. Experiments conducted since 2018 indicate an anomalous presence of a type of speculated interstellar signal, delta-t delta-f polarized pulse pairs, thought to be possibly sourced from a celestial direction near 5.25 hr Right Ascension and -7.6 deg. Declination. A recent experiment utilizing a radio interferometer identified anomalous pulse pairs associated with these celestial coordinates. The experiment is described in arXiv:2404.08994. Other experiments produced anomalous results, reported in arXiv:2105.03727, arXiv:2106.10168, arXiv:2202.12791 and arXiv:2203.10065. After the recent experiment was concluded, the interferometer antenna elements were modified to have increased aperture and reduction in radio interference-caused false positives. An experiment was conducted to attempt replication of the previously reported interferometer measurements. Observations are reported here. Apparent replicated falsification of an expected random white noise explanatory hypothesis compels the development and testing of alternate and auxiliary hypotheses.
