Made these and thought I'd share. Just in case someone else needed it. I made these for use with the RTLSDR but they could be used in a QRP scenario or QRO if you use appropriately sized components. Both boards are designed for use with SMA edge connectors, but you could run mini coax to other connector types if needed.
Created the following image for a FM Band Stop (Notch) filter, stole the layout from Adam 9A4QV, but could be used for other types too. Dimensions are 10mm x 30mm. You must keep these dimensions if you plan on using SMD parts. I used 0806. You can print it larger if you're going to use standard caps and inductors.
This one is for HF Band Pass filters but could also be used for other types as well. Spacing is for ~TS50-2 or similarly sized toroids.
I made these in Gimp, so if you'd like the XCF files let me know. Hopefully some of you will find these useful. There are not enough easy to use RF/Ham related PCB images and files available online, at least where I can find them using google. I plan on adding some more that I've made if anyone is interested.
