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
