Well, that didn't go well.

Looking at it, the two toroids on the left are a little close.
I have a layer of grounded copper foil between
the PCB and the filter (insulated of course).

I might rebuild the filter lying flat.


It looks like I only have 40m and 30m for SSB now.
Input is 1KHz 50mv p-p.

Harmonics on CW follow the spur tables.? Only 80m is not usable there.
