Flight 103 through llla These tlights•re released in January and Febrtary,
19i9trom Alamogordo, New Mexico to test the action of the combined ballast
controls (displacement switch and rate-of-ascent switch). Receiving units
were stationed at AlamogordoJ at Miami, Oklahoma and at Nashville, TennesseeJ
aircraft were used both te receive the signal and also to track and poaitian
the balloon by the use of the radio compass.
For the 1'irat time on these flights, a program tiwitch was used to permit
a single transmitter to transmit three temperature signals as 11811 as ballast-
now data and pressure information. By interrupting the pressure and ballast
data tor short intervale of temperature data, all of this information was
tele:metered with the AJI-1 (N.Y .u.) traniDili tter.
Aircraft reception of 600 miles was reported on these flights,. but ground
reception was limited to a:bout 250 miles, perhaps due to mountains surrot.mding
the receiving station.
llo significant data was obtained on four of these flights, and on two
more the principal objective of the flight was defeated by the excessive gas
loss from the balloons.
From the height-time curves of Flights 103 and 107 (Figures 50 and 51)
may be seen that even with constant ballast flow (at 2400 grams per hour)
