The newly revised Constitution and By-Laws and the Ritual became effective at the close of the 1970 Pittsburgh Grand Conclave. H. Carl Moultrie I, Omega's only National Executive Secretary to this point, was appointed as a judge to the Superior Court of Washington, D.C., in 1972. Moultrie's resignation was accepted with regrets. Omega conferred upon Moultrie the title of National Executive Secretary Emeritus which was later changed to Executive Secretary Emeritus. The Seventies brought more unpleasant news. Founder Oscar J. Cooper entered Omega Chapter in 1972. In 1974, Edgar A. Love, the only surviving founder, entered Omega Chapter.

On November 16, 1975, an impressive granite monument was dedicated to the memory of the four founders. The monument is just a few feet away from Thirkield Hall, the site of Omega's birth place on the Howard University Campus. A revived Life Membership Program resulted in a very large number of new Life Members. The 1976 Atlanta Grand Conclave was the largest in the history of the fraternity up to that point in time. Many new undergraduate chapters were chartered, because of the increased enrollment of black students at previously all-white colleges and universities. "Operation Big Vote" was successful in getting thousands of black people to vote in the 1976 election. Many Omegas were active participants. The 1979 Denver Grand Conclave made a commitment to contribute a minimum of 250,000 dollars to the United Negro College Fund over the next five years.
