Editorial: Time for a Change

The author is leaving the Editorship of this Transactions because it is "time for a change." He has been the Editor since 1968. In that time he has expanded the scope of the Transactions into the fields of computer communication and communication electronics. He also encouraged the formation of the two Technical Committees which now represent these areas. He also would like to take this opportunity to thank the large number of people who worked so hard to make his Editorship a success.
