You would think that I would not make such simple mistakes when laying out a board. But yeah I put the RF in to the filter to the top of the divider, not into the middle of it where it belongs. Anyway, not a total disaster, cut a track and solder in a bodge wire and its fixed until its broken.
Figured while I am at it, to update the schematic and gerber files and put them all up here for anyone interested in building their own, now that I know things are right and should work without much thinking. The filter is a double tuned circuit, the design software for this type of bandpass filter can be found in EMRFD and I have it for download here on my blog.
