Abstract
A recalibration of the luminosity-linewidth technique is discussed which introduces (i) new cluster calibration data, (ii) new corrections for reddening as a function of inclination, and (iii) a new zero-point calibration using 13 galaxies with distances determined via the cepheid period-luminosity method. It is found that H_0= 82 +/- 16 km/s/Mpc (95% confidence)
