The men assigned to erect the tower arrived at Dirks- land on February 10 and completed their job on the same day. Meanwhile, the town of Barendrecht had been selected as the site of the other radio communications terminal. Barendrecht, 5 miles from Rotterdam, is the location of another telephone exchange. The second tower and transmitter-receiver were installed there on February 9. Prospects Doubtful at First Installation at both ends had been completed by the evening of the 10th. Lacking adequate maps, it was impossible to determine the exact bearings or distance between terminals so the decision to use or not to use the repeater station had to be postponed temporarily. The distance that had to be spanned was approximately 22 miles, two-thirds of which was flooded, giving no satisfactory spot for a repeater tower. Because of the limited height of the 60-foot towers and the hck of natural elevations, little hope was held out for depend- able communications under this arrangement. On the IIth and 12th, attempts to establish contact between the two terminals were unsuccessful. Sum- moned from Fontainebleau, I arrived late on the night of the 12th with accurate maps of the vicinity. With their aid the antennas were reoriented, and contact be- tween terminals was established at noon on the 13th. The signals were of sufficient strength to enable Captain Charles C. CuUey, the officer in charge, to decide that the repeater would not be needed. Even though the radio relay equipment was not in- tended to operate into the particular type switchboard used at Middelharnis this minor difficulty was quickly solved. A step-down transformer was located and used to reduce the 115-volt supply voltage to that needed to operate the switchboard drops. Communications from Middelharnis to Rotterdam was checked out on the 14th of February. Twelve voice channels of the 24 available over the microwave system were placed in use. These radio circuits continued in operation until March 2 when the telephone officials informed Captain Culley that the cable damage had been repaired. There was no funher need for the microwave equipment. The Dutch Telephone Company and the Signal Corps ex- pressed thanks and congratulations for a job well done. G.l.'s erect emergency microwave tower near Rotterdam to supply commun'cations over Holland's flooded areas. RCA microwave transmitters like the one above replaced ruptured phone lines after European floods. RADIO AGE 15
