FuG III installation

Recommended Posts


The FuG III was the standard radio installation used on twin engined and larger Luftwaffe aircraft until it was gradually replaced from about 1939 by the FuG X. The FuG III remained in used on transport aircraft until the end of the war. It was also widely used as ground station for ground to air communications. The installation consists of a E2 receiver and the S3 transmitter (during the war the slightly improved E2a and S3a were used).


Both receiver and transmitter operated on two bands, long wave and short wave. The receiver was supplied from a battery box while the transmitter required a propeller driven generator. This meant that the transmitter could only be used once the aircraft was airborne, so later version used a U3 Umformer to power the transmitter. An automatic antenna relay was added to the installation (shown on top of the receiver, left) to facilitate easier switching between reception and transmission. An extensive suite of test and calibration equipment was developed for the FuG III installation, some of which is shown on the left of the transmitter on this photograph:


Left of the transmitter are two units: the PQK2 crystal calibrator (bottom) and PKA2 artificial antenna (top). The grey unit on the left is the PMK "Prüfmeßkoffer", a power supply and control unit that allowed the installation to be tested on the ground (remember, early installations only had a wind powered generator for the transmitter). The PMK was also used to power the installation in ground installations.
