Editor's Note, Mar. 1975

Beginning with the February 1975 issue, Dr. Don Parker is the Editor of the IEEE Transactions on Microwave Theory and Techniques. Dr. Parker is well known to the MTT community through his technical contributions, his long-standing involvement with MTT Symposia, and as a member of AdCom. I heartily welcome him to his new post and wish him well, knowing that the TRANSACTIONS is in good hands.
