SIEMENS RK25 Reflex Klystron
              Luftgekühltes Reflexklystron
              Klystron reflex
			  The RK25 is an air-cooled reflex klystron with resonant cavity for use in modulators and
			  oscillators for frequencies from 3.4 to 4.5 GHz. The klystron delivers an output power of 180 mW.
			  It was used in telecommunications during the 1960's - 1970's.

			  In this model, the tuning of the klystron cavity is accomplished via a mechanical worm drive
			  with a micrometer style readout and a fine thread which varies the dimension of the resonant cavity.
