Radio continuum observations of 88 O-type and early B-type stars are examined. Results are presented for a subset of these stars which forms a distance-limited sample of all OB stars within 2.5 kpc of the sun. Mass loss rates are derived for HD 15570, HD 166734, HD 151804, HD 152408, Alpha Cam, HD 169454, and Zeta Sco. All of these very luminous OB stars are found to be losing mass at a rate on the order of 10 to the -5 solar masses/yr. Multifrequency observations confirm the free-free interpretation for Zeta Pup and provide evidence for variability in the free-free sources P Cygni and Cyg OB2 No. 12. 63 refs.
