Re: #QDX V3 filters and low output power #qdx


Hello Roelof,

Many thanks for the feedback.

In fact I think that the 40m LPF cut off is starting to fall off before the 40m band starts. Slightly less induction or a tiny amount of additional capacitance might sort it.
For 20m, that first dip, like the indentation in a tooth, could be responsible for reduced output. I seem to think that the high frequency fall off should start around 17MHz?
