DEU - Fu. H. E. (monitorovací přijímač)

Fu.H.E. monitoring receiver


Even before the start of World War II, Germany began to produce special receivers designed to monitor (eavesdropping/monitoring) radio transmitters with an emphasis on detecting and exposing illegal stations. Gradually the company. Lorenz and Telefunken developed a number of versions that were used by police and military ground and air units.


The receivers excelled in sensitivity and covered a wide frequency range from 75 kHZ to 305 MHz. In conjunction with an "attachment" - a goniometer with a frame antenna, they also served as radio direction finders. The direction finder was determined by hearing - to the so-called minimum audibility.


In terms of division there were 3 groups:


I. "generation" (Band 75 kHz - 3.333 MHz)


1)Fu. H. E. 1 (r. 1939)
Frequency band: 75 kHz - 3.333

II. "Generation" (Band 75 kHz to 305 MHz)


These receivers were marked with the codename "Horst" and the letter of the respective version:


1)Fu.H.E.a(1939) "Horst A" - "Anton"
Frequency band: 75 - 857 kHz


2)Fu.H.E.b(1939) "Horst B" - "Bertha"
Frequency band: 857 - 3750 kHz


3)Fu.H.E.c /c1 (1939) "Horst C" - "Cäsar"
Frequency band: 3.75 - 25 MHz


4)Fu.H.E.d /d1 (1939) "Horst D" - "Dora"
Frequency band: 24,5 - 61,0 MHz


5)Fu.H.E.e(1940) "Horst E" - "Emil"
Frequency band: 60 - 151 MHz

6)Fu.H.E.f(1943) "Horst F"-"Friedrich"
Frequency band: 145 - 305 MHz


III. (Band 0,73 - 160 MHz)


1)Fu.H.E.u / u1 (1940)
Frequency band: 0.75 - 25 MHz


2) Fu.H.E.v / v1 (1942/43)
Frequency band: 24.0 - 160 MHz

Pěkná sbírka "Horchů" či "Pavích ok" jak se také těmto přijímačům říkalo
