Default 80W.S.a

I have started to work with 80W.S.a also.
It worked right away.
I ask you, and especially Funksamler:
How was this used?
Which military used used this?

This will be interesting. Here's a video I made a while ago with the 80 Watt Transmitter and it's Umformer:

The 80 W.S.a was developed out of a need to increase the range of the panzer division's medium wave command network. The Wehrmacht was disappointed with the range of the FU8SE30 and found that units operating at some distance from the bulk of the division lost communication. This was a particular problem for the armoured reconnaissance units which could operate up to 100 Km ahead of the main force. They had to be equipped with the Long Wave 100 W.S. which meant that a relay was required between the reconnaissance and the armoured units. This problem must have increased even more in the African and Russian campaigns were distances were even larger.

So how the increase the power of an existing transmitter? The easiest way was to increase the anode voltage, in case of the 80 W.S.a to some 800 Volts. This required better insulation and larger air gaps than were available in the 30 W.S.a, so as a result the height of the transmitter was increased somewhat and a larger power supply connection (with larger distances between pins) was installed. They also changed the method for generating the negative supply voltage (-300V), but other than that the 80 W.S.a was pretty much identical to the 30 W.S.a. This means no significant retraining of operators was required.

So you will find the 80 W.S.a in reconnaissance vehicles such as the Puma, the Lynx and the Sd.Kfz.250. It was also used in higher echelon command vehicles, such as the "Kommandofunkwagen". It could also be found in soft skin communications vehicles such a the Kfz 17.

Funksammler

Default Thank you for info.

Thank you so much funksamler.
I'm impressed with everything you know about this.
Hope I can use the information on my page.
I want to write that it comes from "Funksamler".
Possibly we could test a CW QSO sometime later?
Thanks also for the interesting film Yuri D.
I also have this motor converter, but I'm missing the cable.
So I will first modify a ham built power.

Thanks, LA6NCA
