well i bought the pcb from rf parts..it arrived today..but i forgot to
order the pcb layout info..its for the 140w push pull amp based on the
motorola design..anyone got the pcb layout info please?????

i wanna build it,and i know i could work it all out ,but it will save
hours of work if someone (prehaps in the usa )has the info...

thanks g0zen


Well, most of Helge Granberg's Application Notes are on the Internet (in
various places)

Mike Grierson G3TSO built his 140 watt HF amplifier also based upon Helge's
design,
using the Communication Concepts (CCI) printed circuit board.

Was this the VHF (2-meter) or HF amplifier TX100F from RF Parts ?

it was the tx100 i guess...anyway the links you put up are the ones i
have..(except the component layout ,as i forgot to order!!)

yes you are correct in stating they are based on h.granbergs
designs,which i have,as i stated i guess i could work it out,but it
would be much easier to know the component layout for this pcb..as it
is not exactly as per his design..
