'zfa:.`L,'L I:v Construction of Lugger PranL;riit.ters by the RF`P F inl werk Koe'!eni c'A: The lugger antaiiiitter, built by the RFT Funkwerk Koepenick, was used in a trial run from Rostock as far as to the polar sea during the period I to 28 October 1952. Tie transm:tter was developed by Engineer Richter (fnu) with Engineers Grirm and Retz participating In the trial l. The allwave receiving set was used during the test which p:-ovcd very satisfactory. Radio cormunica. t-i.on was possible from the lugger to the Funkwerk, on a frequency of 4 mega- cycles on a 24,.-hour schedule. 2, An improved model of the lugger tranarritter was completed by the Abteilung Schiffsfunk (Ship Radio Department) Ln December 1952. The wiring was slight- Jy- changed in the second model and the design considerably in-proved by the use of three mechanically coupled revolving coils (mechanisch gekoppelte Spul en- revolver) resulting in an extremely accurate frequency adjustment. 3. The improved transmitter ' as also usf:d as control stage (Steuerstufe) for the KN 3 transmitter which was equipped in the terminal stage (Endatufe) with a 782 Telefunken tube. With respect to the power supply a capacity of only 3 kw was provided though a capacity of 6 kw, at 24 megacycles, was echieved in preliminary tests with the Kai 3 transmitter. 25X1A comment: Possibly Dr .
