Hello all,
Thanks to the help of Jelmer, from the PA6Z
contestgroup with his camera I'm able to show some
pictures of the new 136kHz station I'm building at
the moment.
I hope to have finished all stuff on time to take
it to LX later this year.
You can find the pictures, as well as regular
updates (pictures as well as text) on
My plan is to put all components that might get
warm into a kind of 'chimney'.
These are the output transformer, zobel network,
output filter, as well as
the RF-choke, and shuntresistors for
currentprotection.
Also some parts of the low voltage
circuit.
I am building the station in 'blocks'
The pictures taken show the powerstage with 4 times
IRFP450.
Also visible is the antennarelay as well as a part
of the driver unit.
Maybe David may recognize the 3C90 core,
