| Avionics FuG7 radio FuG7 is a radio with short wave. This radio could not emit and receive at the same time, which obliged the pilots with a strict discipline for the communications in flight. It was used for the communications air-to-air and air-to-ground, emitted with a power of 7 going Watt on a beach of frequency from 2,5 to 7,5 MHz. FuG7a radio Version improved of radio operator FuG7, this radio made it possible to speak and to listen to the radio operator traffic simultaneously moreover it was possible to emit in Morse. FuG16Z radio This radio simultaneously made it possible to emit and receive air-to-air communications and air/sol, which made possible guidance towards other planes or a station on the ground. FuG16ZE radio Radio of edge conceived specifically for the hunters, this version of radio allowed, in addition to the air-to-air communications, electronic guidance using the device "Y-Jagdverfahren". Guidance in phone starting from the ground was not, on the other hand, more possible. Electronic guidance and the communications were possible simultaneously. FuG16ZY radio Version improved of FuG16ZE with which it was possible to guide the hunter towards an objective. FuG16SZ radio radio special Version of the FuG16ZE model intended for the planes of support. The capacities are the same one except that guidance and the communications were not possible simultaneously. FuG25 radio intended for the air-to-air communications and air/sol moreover it allowed the radiotelefony for the communications with the troops on the ground. FuG25a Nowadays, this device would be called IFF (Identification Friend & Foe), identification friend and enemy. In short, this apparatus which equipped all the German planes, worked with the same frequency as the radios. To the reception of a signal emitted by a station on the ground, this device turned over the signal after having modified it. What allowed to the operators radars to differentiate the friendly and enemy formations. Nevertheless, this device had limits, because as soon as the planes were in the vicinity or the contact with the adversary it was not possible any more to differentiate the apparatuses on the radarscopes of the time. FuNG101 FuNG101 is a device of radio probe (raising real height compared to the ground). Developed by the Siemens firm, it was intended for the twin-engine hunters, because heavy (16 kg). I do not have information as for his assembly on Fw190 of hunting of night, although that was considered and tested in Rechlin. Working on a frequency of 375 MHz, the precision of this device was approximately 2 meters. The FuGN101 version was effective between 150 and 1000 meters of altitude and the FuGN101a version between 150 and 750 meters. This device was characterized outside by small vertical antennas under the wings, it equipped primarily the aircraft with hunting of night. FuG125 This device was used for guidance of the apparatuses using a transmitter on the ground, a kind of "all things considered VOR"! Called "Hermine" the apparatus 10 kg weighed and worked on a beach of frequency going from 30 to 33,3 MHz. Under optimal conditions, the range could go up to 200 km with a precision lower than 3°. FuG217 board radar  Developed by Siemens, this device, called "Neptun" is in fact a radar of continuation embarked for the hunting of night. There existed in 3 versions, for twin-engine hunters R2 and V/R and for the single-engined aircrafts the J2 version.  The R2 version was used as alarm towards the back of the hunter, version V/R combined the continuation (forwards) and alarm while the J2 version functioned only forwards. This radar could emit on 2 frequencies, 158 and 187 MHz, its range useful was 400 to 4000 meters and the taper angle of research is of 120°. The antennas were appeared as rakes and small needles distributed on the wings and the fuselage. The unit weighed from 27 to 35 kg according to the version (antennas included/understood). Some Fw190 (I am unaware of the exact number) were equipped with this device in the J2 version. FuG218 board radar This version of the radar "Neptun" rises from permanent improvements of the FuG217 version. There also existed in 3 versions, for twin-engine hunters R3 and G/R and for the single-engined aircrafts the J3 version. The R3 version and G/R have the same functions respectively as the R2 versions and V/R, the J3 version had the same functions as J2. The improvements related mainly to the power of emission which passed to 30kW, the use of 6 frequencies between 158 and 187 MHz, and the useful range which went from 120 to 5000 meters. The cone of research always made 120°. Version G/R, intended for the twin-engines, weighed 50kg. As on FuG217, the antennas of R3 and J3 were presented in the form of groups of small needles and version G/R in the shape of rakes directed towards the front one. | |||||||||
