On 1 March 1945, the personnel at Birdum Telecommunications Unit moved to Gorrie airfield to establish 55 Operational Base Unit W/T Station

Gorrie was a new modern camp located on the west side of the Stuart Highway about 9 miles north of Larrimah and a mile from the Gorrie airfield. The RAAF's 14 Aircraft Repair Depot was located at Gorrie airfield

Squadron Leader A. Crudington was the Commanding Officer from 28 June 1945 taking over from Flying Officer R.T. Hughes.

The Unit's signals responsibility increased greatly to include aircraft spare parts needs, movement notifications for the 6,000 personnel and 60 a week repaired aircraft movements for 14 ARD.  Their radio traffic increased dramatically over the closing stages of the war. At one stage they cleared 650,000 groups in one month. The Base closed on 24th December 1945.

After the war, the Gorrie Signals Building was sold to the Bovril Company at Katherine. It was ultimately taken over and relocated to be the administration building and owner residence for a then local caravan park.

A Crede Head is a mechanical unit which processes pre-punched paper tapes, made on a separate punch machine, representing morse letters (dots and dashes). The paper is loaded to pass metal contacts which either pass through the tape or not, so making morse symbols with the pin electrical contact. The tape speed can be varied by increasing or decreasing the motor drive speed. Transmission speed to 40 words per minute was a high speed rate. The unit was used when a long weather forecast broadcast was made or repeated, so alleviating the operator fatigue and involvement. The Crede unit was made by AWA Australia and used extensively on weather broadcast stations such as Gorrie and WXXU on Biak Island in the Celebes.
