[ARC5] 200690713819 EBay German receiver, and...

[Meir Ben-Dror WF2U]

It has a BFO, but no tuning.

The mode switch is  marked Tön/TFN – Tonlos – Tonfilter: Sound/Telephony i.e. Phone – Without tone i.e.CW –  CW with filter.  The rest of the labels:  Lautstarke: volume control; Wellenbereich Schalter: (Wave)band Switch; Abstimmung: Tuning; Empfanger Regler: Receiver control i.e. RF gain. 

 

Hope this helps.

Thanks Ken.  I thought the arrangement of the tubes was strange.

What is it?  There seems to be a 4 x 6 grid of tubes.

 
Well, it is an HF receiver with 8 bands. The tuning window shows 6.5 to 11.5 MHz. From the 
coils on the bottom, it looks like there are, maybe, two RF amps, a mixer and an oscillator 
stages.
 
I don't know German, so can't interpret all the controls, but it seems pretty obvious that there 
is no BFO, or if there IS one, it is untunable. There is an AF gain, or "Loudness" control, and 
what appears to be a tone control.
 
It apparently uses an external power supply, as there is a bundle of cables coming out of one 
rear side.
 
I am betting that it is a German version of the usual "moral" or troop entertainment receivers 
which most larger U.S. Navy ships carried.
 
After I posted a comment to the seller that his schematic was of an ARC-5 receiver, he called 
me on the telephone. He lives in Boise, Idaho and has had the receiver for 10 years. He has 
been trying to find information on it since then. I pointed him to Jan-Martin LA8AK, who has a 
large collection of German WWII radio gear. Jan may be able to help him.
 
>From what I can see, I THINK the schematic is of the BC- band ARC-5. The IF frequency is 3 
numbers, and the only one that I know of is the 239 kHz if of the BC band receivers.
