  This paper details speckle observations of binary stars taken at the Lowell
Discovery Telescope, the WIYN Telescope, and the Gemini telescopes between 2016
January and 2019 September. 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 ~2 mas in separation, ~1-2 degrees in
position angle depending on the separation, and $\sim$0.1 magnitudes 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 trinary star HD 173093, we calculate masses with
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 AU, that is, on
solar-system scales.
