RF Filter PCB Jig

This is a quick jig I made to cut and drill RF filter boards compatible with the QRP-Labs.com spec. Definitely cheaper and easier to buy the lowpass and bandpass filters from them, but in this case I needed a high-pass filter to knock out the AM broadcast interference, and figured why not make it the same size so it, and any other homebrew filters I make, will fit into QRP Labs band-switching boards and other projects. It's a handy standard.

#### To use:
- Slide the corner of a piece of copper clad into the slot to mark the size.
- Cut out the board. Be sure it fits exactly into the depression in the jig
- Clamp on top of a scrap board.
- Drill all four holes (I used a Dremel and some little PCB bits)
- Flip end-to-end and repeat
- Scribe out the pads as needed for your project
- Solder on the headers, capacitors, and inductors as needed

#### Notes
- .scad file included in case you want to tweak hole sizes
- extra set of holes were in case I wanted to use this for the
