Good afternoon,
The problem seems to have been the input filter, exactly why I have not
figured out. I pulled that filter and put a jumper in its place and "bingo"
no SWR on 40 (or the other bands) and full power out as it should.
The "PI" filter (actually is more complicated than a PI - it has a third
inductor and Capacitor to ground tapped from the middle of the inductor part
of the PI. I imagine that part is designed to pull certain higher
frequencies to ground.
Now I want to modify it so that it will OP on 10 and 12 Meters. Has anyone
gone through this MOD?
