withifi” these tolerances and by judiciously selecting individual tubes, sufficient sjcaration of frequency may bo obtained to prevent serious interference. ‘ho 97th Bomb Wing Detachment was instructel by Twk to sclect magnetrons with frecucncics between 9320 ani 9375 MCS and that the «ir task Group aircraft radar frequencies would bo between 9375 and 9430 MCS with a ninimm soperaticn of five MCS. Tho Bg7D offects airer-ft exporicneed minor radar failure. Tho deflecticn coils in the pilot's {£ndicstor burnad out for no apparent reason. On investigation, it wes found that tho operator frilel to mako nocessary changes in tho junction box for ono scope operation. Howover, this was not normally meintenance performed by an operators This gave improper functioning of Cisplaced contor. = With the excep . tion of the displaced center operation, PPI operation wos normal end satisfactory. The RB~36 control areraft encounterod minor radar difficulties during the operation. The gomraticn of the indicator reticles failed becnuse of improper soldering in connectors in th cross hair resolver, and the wind slew control feiled bocause of a corroded switch contact. Closer insjcctions wuld eliminate thcso tz-uties in tho futuro, The cquipment in the .0C performed satisfactorily. Oae airborne IFF in VILSON 1 was wook giving a maximm rmgo of 25 milos, ‘he fightorcirgraft were observed .2t maximum distences of 235 milts, Rogarding Reydist, the FM link for the system usol witn the B~36D wes not opersting properly -nd therefore no date was obtainod. 74 "76
