A few weeks back, I wrote because I was not getting the results I expected from my measurements. I replaced the cap and coil with "known" values, being more careful with those tiny SMDamnedSmallDevices, and sure enough, the coil is now measuring what I expect +-0.1 uH, and the cap is within 7%, so I am happy.
I have ordered 2 RF demo boards, one from DeepElec and one from NWDZ --- maybe --- and I look forward to playing with them. I don't know what questions they will raise, but when it comes to 2-port measurements, I don't have the experience, so it will be fun learning.
