LF: TX system at DK7FC, schematic

[Stefan Schäfer <Stefan.Schaefer@iup.uni-heidelberg.de>]

Hi Terry, LF,

I want to add something to the TX/antenna matching discussion. There 
have often been querys about a schematic of my TX/PA system. So i 
finally took the time to draw it, how it looks in principle. It is just 
one example how it can be done of course. Maybe it helps to get further 
ideas how you can do it one your side.
