Re: LPF frequency curves #lpf

I put a couple of documents about filters and design software, in the files section. I worked through the modeling and simulation of the stock 40 meter filter and an optimum design. Then, I constructed both designs and did measurements - for those curious about how the filters work and possibly why the parts variance has caused some to have low power output. The optimum design might be a solution for you (or not).
