To KK7UV and topband list
You need a well wound input - output ferrite toroidal transformers to
combine them and get a broadband match to 50 Ohm and
some kind of feedback and a proper level of bias current. They work
well. For just some photos take a look in my web site at:

HOMEBREW GALLERY by I4FAF, then click SRC-02
Let me know if you like that device as it appears.
Merry Christmas and Happy New Year to all TOPBAND reflector.
