Hi,
Inspired by our Weitling discussion I have decided to rock the boat. In Trenkle Funkmess AEG edition p. 87 there is a picture without a caption. I always assumed that it was a Freya EGON version. As it was different from a EGON 1 I called it a EGON 2.
One such system was found in Denmark in Stellung JASMIN near Hjørring, please see photo attached. And drawings for comparison.
However apart from the picture of Trenkle and the two in my collection I have never seen other pictures nor documentation for this system. Anybody?

SES, the picture in Trenkle/AEG has a caption. It is a common caption for both the drawing and the picture at the same page, saying "Prinzipskizze... und Bild der Antenne von Weitling". The drawing is the "Prinzipskizze", while the quote "und Bild der Antenne" refers the picture of antenna.
It looks somehow different from the example found at JASMINE:
- pic. in Trenkle's book: two antennas are separated
- pic. from JASMINE: two antennas are close to each other
In both cases the vertical dipoles look very bold (thick) - and there are 8 of them in a row.
But the latter feature seems to characterize Gemse receivers of many Freya variants.
Perhaps the lower (transmitter) antenna could have been moved vertically in order to change radar behaviour regarding to its local characteristics and performance?

Hi Michal,
At my age please don't expect me to read everything
An now it becomes interesting. The gap between the two antenna elements can be due to the perspective, but there could be a wider gap in Trenkle's picture.
If this is the Freya EGON 1 Weitling, what then is the name of the system with the two different antennas and the large gap
What also bothers me is that FuSAn usually is used to describe a system sometimes consisting of a number of elements, whereas FuMG is usually used to describe a radar.
Also the thick dipoles indicates frequency agility like on Dreh-Freya, Wassermann M IV and Jagdschloss, but that does not make sense since the FuG25 used a fixed frequency.

What dipoles did it have? Thick or thin?FuSAn 730 = transmitter & receiver in one device - but it was not a radar in German termsSES hat geschrieben: What also bothers me is that FuSAn usually is used to describe a system sometimes consisting of a number of elements, whereas FuMG is usually used to describe a radar.
FuSAn 731 = a system consisting of 2x FuSAn 730 + Fernuebertragungsanlage + Auswertetisch

Michael, you are right about Flamme designation as FuMG.
I personally think that designating EGON1 as FuSAn might have been caused by the fact, that it was not used as a "detecting radar" (like, for example, secondary radar Freya Flamme), but strictly as a navigation aid - i.e. an example of Funk-navigations-sende-anlage.
Thus a single Freya, after modification to EGON1 form, became a pure FuSAn instead of FuMG.
