direction of Dr. Olt Würt Radio gesellschaft m.b.H. had just finished the
development of a 2 tube radio sonde transmitter which if the war had continued
would have been Germany's standard unit. However, production of the new
transmitter was never begun. ... A conventional Radar station beams an impulse
link to the sonde in the air. The sonde receives it, amplifies it 20,000 times
and without a time delay beams it back to the station on the same wave length.
The receiving and re-beaming of the impulse link is effected by a pendulum
generator which periodically blocks and opens the transmitter .. The
meteological signals are modulated on a small 3 m transmitter and via a normal
receiver are recorded at the ground station... RD2,4Ta made by Lorenz DDD25 made
