We compare the chromospheric and coronal emission levels in an essentially bias-free sample of K dwarfs. We find a rough power law relation between the normalized soft x-ray flux and the Mg H h + k flux, and we find further evidence of a minimum surface flux level for Mg H h + k emission in cool dwarfs.
