My Low Pass Filters

With repairs of my boat almost complete, I can return to some Ham Radio projects.

The following are the files and artwork that I have used to create the Low Pass Filter, see my previous blog posts. As previously posted, the value of components were selected from junk box parts which are a close match as computed. The artwork is provide here as an ".svg" file suitable for use with Inkscape or other vector graphics programs. The intent is to allow space for as many identical parallel capacitors as necessary to provide the correct values. The coils are wound and measured as necessary. PCB SMA edge connectors are soldered on both sides of the PCB and are used to make connections easy.
