Fu. H. E. c |
| |
| This receiver was first released in 1938 by Telefunken and was considered the "next generation" of high accuracy monitoring receivers. It was from a series of six similar receivers that covered a wide frequency spectrum: Fu. H. E. a (72 - 887 KHz), Fu. H. E. b (857 KHz - 3.75 MHz), Fu. H. E. c (3.75 - 25 MHz), Fu. H. E. d (24.28 - 61.9 MHz), Fu. H. E. e (60 - 145 MHz), Fu. H. E. f. (145 - 305 MHz). Some of these receivers were manufactured by Lorenz and others by Telefunken. Because of their multi-colored frequency scale, they are known as "Peacock Receivers". |

Here are some details of the central section of the console. Here you can get an idea of the original paint used on these receivers. |
|
|
The bandwidth adjustment and volume adjustment potentiometer controls. Below is the tone-selector switch to fascilitate CW communications. |
|
|
The signal auto-regulator switch is on top, and the telegraphy/telephony switch is at the bottom. Notice the clear Waffenamt stamp in the middle. |
|
|
The very smooth and precise frequency control knob. This is a double knob where the top wheel is the fine adjustment, while the bottom wheel is the coarse adjustment. |
|
|
The beautiful volmeter for the Fu. H. E. c. This is the correct voltmeter for this model. |
|
|
The vacuum tube test selector switch. The instructions read "set - depress" |
|
|
The antenna coupling control. This allows the operator to regulate the strength of the signal coming from the antenna to get the maximum reception with minimal signal distortion. |

The right side of the Fu. H. E. c. with the cover removed. Here you can see the coil turret drum, the power socket, and the headphone sockets. |
|
|
The rear of the Fu. H. E. c. Here you can see the detector tube and the low frequency tube. At the top of the photo you can see the antenna coupler on the left and the tube voltmeter on the right. |
|
|
The left side of the Fu. H. E. c. with the cover removed. Here you can see the two high frequency amplifier tubes, the Superheterodyne unit (mixer and oscillator tubes), and the three intermediate frequency amplifier tubes toward the bottom right of the photo. |

Here we're testing the radio with our vertical antenna and power from two bench-top power supplies. |
|
|
The power connections and two period headphones plugged into their sockets. The radio was loud and clear on all frequency ranges. Another stroke of good luck is that the tubes were all good and strong. |
|
|
Then we used the NA6 power supply - set to the Kw. E. a mode to power the Fu. H. E. c. Since the Fu. H. E. c. has virtually the same power requirements (and the number of RV2P800 tubes) as the Kw. E. a, we can use the same power supply. The results were excellent with both fillament and anode voltages supplied correctly. |
