His knowledge and interest in aerial navigation later supplemented by concerns for air defense led him to work with Hansen and his brother on microwaves, contributing his enormous practical and organizational skills [ 15]. In frequency stability the klystron was all that the radar engineers could have wanted, but it did not have adequate power. The power level is proportional to the intensity of the electron beam, and as in the cathode ray oscilloscope1 the electrons repel one another, so that as one attempts to increase intensity the beam diverges and the desired effects are soon dissipated.
The German contrast is stark. The German work started soon enough. In November 1938 a meeting took place about recognition. It was only then that the Naval Command learned of the separate radar work for the Luftwaffe by Telefunken and Lorenz.

It gave identification only in direction, not range, at the time not thought important for Flak. Martini's demands that the functions of these two devices be combined were ignored [ 15]. The Technical Bureau of the Reichsluftfahrtmisisterium (National Air Ministry), the government agency resposible for aviation matters, brought forth a modification of Stichling called Zwilling (twin) for which production began in early 1941 with 10 000 eventually being installed, this despite a report from the Air Research Station at Rechlin that the device was completely unusable.
