10 Development of a goniometer direction finder (Goniometerpeiler),
which was carried out by Department TEE of Funkwerk Koepenick during
25X1 1952 under plan number K2-32, was taken over into the 1953 develop-
ment program under plan number K3-40. The goniometer of the instru-
ment could not be completely developed during 1952p when the project
was carried over to 1953, it was placed under the scientific.-technical
supervision of Wilhelm Grimm, with Erler (fnu) as technician in charge.
The following are the 1953 plan characteristics of the project:
Continuation of the development of a
goniometer direction finder (100 to 305
MFz )
Key words Goniometerpeiler
Tee raical Characteristics: The sensitivity of a normal receiver
with a preset goniometer is
not sufficient. Furthermore, develop-
ment provides for the construction of a
trial model with the following parts:
Cross frame9 goniometer, direction
finding input connection (Peiiainga.n;rrs
schaltung), receiver with four ranges,
power supply 24 Volt D.C., power
supply 220 Volt A.C.
Total cost is to amount to 1109000 DME
including 34,000 DME for 1952 and 239000
DME for 1953.
Construction of a model and completion of
its trial operation by the second quarter
1954
