Book on HF Filter Design

A project to capture how to design and build KW filters for HF was begun in December 2021 with completion anticipated around late 2022/early 2023. The application of the governing equations is included and the Appendix gets into the mathematical details of their derivation. Two chapters outline the design and construction of a 40m and 15m bandpass filter. A large amount of detail on capacitors and toroids is included with a great emphasis on the use of Norton transformations.
