Campbell suggested they might use the 75-ft tower on Eninzan for a relay station and to remoteecontrol the buoys; they had planned having their own radio control system but he thought they might be able to tie in with EG&G's radio signals on this. (Incidentally, BG&G will © furnish six radio signals.) This is new information to Thaler and friends; they are considering it, will send a man to EG&G to investigate thige It was asked, if they can retransmit from the 75-ft tower, must they then go to an aircraft or could they use a ship? The answers line of sight and range requirenents necessitate the plane; also they do not wish to run their equipment on a ship because of demands for other power. Therelay station is for the purpose of getting the aircraft far enough away that it is out of the blast and thermal range. The buoys will be cylindrical cans with dished heads, caloulated to withstand a static load of 1100 psi, compartmented with watertight sections. The inner section, containing the electronics, magnetic tape recorders, etc., will be shock mounted. There is a heat shield at the top and two antennas sticking out of the top, one channel for the comand link and one for the telemetering. A beamed, Yogi-type antenna will point directly toward the buoys, the signal will feed down into the receiver and then transnit from another beamed antenna to the aircraft, where it will be picked up and passed to the oscillographic recordere This project is testing qut some of the antennas on Upshot- Encthole Shot & willtry to scale theirpositions so.they. will-be-inthe same blast and thermal range. ! re | DELETED _ | DELETED frodiGreenhouseandat the © recommendedtneylook at Frolich'sdata WBS gamma intensity as a function of time data andsee at what gama levels Frolich's transmitter started working again (it cut off at sero time, came back on a second or so later.)
