The observations taken at Gemini and Lowell were done with the Differential Speckle Survey Instrument (DSSI), and those done at WIYN were taken with the successor instrument to DSSI at that site, the NN-EXPLORE Exoplanet Star and Speckle Imager (NESSI). In total, we present 378 observations of 178 systems, and we show that the uncertainty in the measurement precision for the combined data set is ~2mas in separation, ~1{deg}-2{deg} in position angle depending on the separation, and ~0.1mag in magnitude difference. Together with data already in the literature, these new results permit 25 visual orbits and one spectroscopic- visual orbit to be calculated for the first time. In the case of the spectroscopic-visual analysis, which is done on the ternary star HD173093, we calculate masses with a precision of better than 1% for all three stars in that system. Twenty-one of the visual orbits calculated have a K-dwarf as the primary star; we add these to the known orbits of K-dwarf primary stars and discuss the basic orbital properties of these stars at this stage. Although incomplete, the data that exist so far indicate that binaries with K-dwarf primaries tend not to have low-eccentricity orbits at separations of one to a few tens of astronomical units, that is, on solar system scales.2021AJ....161..295Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/295CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/131/2681 : Orbits for three visual binaries (Tamazian+, 2006)J/AJ/141/45 : Speckle observations of HIP stars (Horch+, 2011)J/AJ/145/52 : Abundances of late K & M dwarfs in binary systems (Mann+, 2013)J/AJ/150/151 : DSSI obs. of binaries.
