Dear Horst,
in the
internet I have read that DK8KW, Holger Kinzel at Peine, also has a DEBEG 7121
transmitter, including its full documentation. He had also used it for the the
beacon he had operated around 500 kHz.
Perhaps You can get
the information from him.
OK?

Hello
all,
some month ago I got two PA modules for 500kHz. Unfortunately I
got only a few pages and a schematic about the modules but not about the
complete transmitter. The modules were introduced to me as parts of a former
Non Directional Beacon made by Siemens.
Now I compared the inside view
of the complete transmitter in the rudimental manual with an inside view of
the famous DEBEG 7121. It's quite the same.
That's my chance to find
out the information I need about the units. At the moment the PAs make about
30 db less than at the input. To find out, what might be the problem I need to
know what impedances in and out, what power in?
I am looking for
-
user manual
- service manual.
But any answer to my question (in/put
/ power/impedance) would be useful.
Of course I'd like to own a
complete 7121 transmitter - but I think there are some more here who would
like, too.
tnx es vy73 Horst DO1KHS/DI2AN
