aay
desired vertical angle over all of the operating frequency range from
1 to 23 megacycles,
The transmitting and receiving antennas and the
ground plane were in mutual perpendicular planes with the plane of the
transmitting antenna oriented 53° to the east of magnetic north.
Tonosphere recorder site (C-97 airplane)
a.
Same as for Rongerik and Kusaie, except that a C-3 Ionosphere
recorder was used.
This recorder is the same as the C-~2, except for a
few modifications and improvements,
b,
The transmitting antenna in the C-97 was a single wire delta
fastened to the lateral extremities of the tail assembly.
OPERATIONAL
Ground stations at Rongerik and Kusaie, using 15 second sweep
operated on normal 24 hour schedule:
5 sweeps per hour until H-15
minutes; thence continuous until H # 8 hours; thence routine,
Airborne Station C-97:
Routine operation until H-15 minutes;
thence continuous using a 30 second sweep time until approximately
H ¢ 5 hours.
RESULTS
Ionosphere stations at Kusaie, Rongerik and the C-97 airborne
station operated successfully during this test,
Kusaie:
The effects obsegt®®for this test were about the same
qv
as those observed duringMMMM (creRoKEE) except that the arrival
time of the disturbance in the F region was approximately 5 minutes
earlier at H ¢ 27 minutes,
Rongerik:
The effects were approximately the same as for,
(CHEROKEE).
