History: |
Val Leach a World War I radio operator was frustrated by the two-way communication technology that prevented a receiving telegraph operator from breaking into or stopping a sender's transmission. In 1919, he invented the Leach Break-in Relay, a device that revolutionized telecommunications, launched the Leach Relay Company and began building and selling these relays. With this invention it makes it possible for the receiving operator to break into or stop a sender's transmission thus eliminating the need to resend a message or stop a message with misinformation. In critical situations this could save lives. |
This manufacturer was suggested by Bruce Morgenstern.
