@lmberkhout is testing out a minicircuits filter.

A few notes from Titu@asu:

https://rf-tools.com/lc-filter/ (use this tool to design the filter and choose components)
KiCAD: open source tool for PCB design
estimates ~$10-$20 per board. @lmberkhout thinks that's way too high. pcbway offers $5 for 10 boards

This is very old and I think we've settled on the nooelec filter/amp for now.
