THE NAVY RAN A LAB TEST OF ARA/25 WHICH INVOLVED MODIFICATION OF
THE NORMALLY REVOLVING RHOMBIC ANT $0 THAT IT REMAINEDPOINTED DEAD
AHEAD, . BY THEN ADDING A LOBE ASS SWITCHING SIGNAL THE ARA/25 WAS
MADE TO BE MORE OR LESS COMPATABLE TO THE SARAH, HOWEVER THEY NEVER'
TRIED THIS ARRANGEMENT IN AN ACTUAL FLIGHT. PERHAPS BECAUSE OF THE
POWER PROBLEM, AFTER THIS TEST THEY STILL SEEM TO BE OF THE OPINOgg
OPINION THAT SARAH AND THE ARA/25 ARE NOT COMPATABLEM
WHEN THE TESTS OF THE ARA/25 ARE RUN AT STEAD WE WILL CERTAINLY
INCLUDE A RUN AGAINST TESS THE SARAH IN NORMAL OPERATING CONDITION
IF THIS WORKS OUT THE PROBLEM IS SOLVED OF COURSE. K
1. IS THERE A SPECIFIC DEADLINE FOR THE COMPLETION OF OUR WORK?
2, WOULD APPRECIATE RECEIVING DATA ON THE ARA/25.SYSTEM, IF
AVAILABLE. THAT IS ALL. lc
.I HAVE NOT BEEN NOTIFIED BY SAC AS TO THE STARTING DATE OF THE PLAN
TESTS, HOWEVER IT IS MY OPINION THAT THEY WILL NOT COME OFF BEFORE
1 JUNE. THIS IS PROBABLY AS GOOD A DEADLINE AS ANY. IF IT SHOUKD
.BE EARLIER WE WILL JUST HAVE TO DO WHAT WE CAN.
WILL SEND DATA. ON ARA/25 INCLUDING TEST REPORTS FROM AIR FOREgg FORCE
AND NAVY.
