412 Radio Broadcast THIS FOREST PATROLMAN's PISTON GAVE WAY While in the air near Eugene. Broken crank shafts or other mechanical ills necessitating a forced landing on the side of a rocky mountain are part of the airman's daily life The antenna installed at the main and subbases that were equipped vt'ith two-way (ground) radio communication consisted of the "T-type," the directional effect being used to favor the routes of the airplane patrol. The masts used were eighty-foot trees, felled, hewed, and transported from the forests by the Air Service personnel. The umbrella type of antenna was used at the sub-bases that had no transmitting sets, with the legs of the umbrella spaced so as to provide the directional effect desired on the patrol routes. MODERN APPARATUS FOR inter-field work the patrol net was equipped with three i-kilowatt De Forest transmitting sets located at Mather Field and Corning, in California, and Eugene, Oregon, as well as with two radio tractors, at Camp Lewis and March Field, in California; and an S C R-67A set improvised to use continuous wave telegraphy on occasions when it was not possible, because of interference, to use the voice, at Crissey Field, San Francisco. In addition, the two-control, free net system was used from Eugene, Oregon, and Mather Field — the control stations for Washington and Oregon on the one hand and for California on the other. The two-control stations had three closed periods each day to conduct their administrative business and transmit reports, weather news, etc. These periods were from 7 to 8 A. m., from 12 noon to i p.m., and from 6 to 8 p.m. At other times than these the net was free for each control station to use as its operator desired.
