Re: cool experiment
Again, I am not sure what you are asking. Obviously these low cost VNAs can measure S11 & S21. So I read the paper thinking maybe there was something there that would make you ask. It seemed straightforward enough. Lets spend a few minutes and toss something together.
I don't have a 1uH, so wound up a coil on a chapstick dispenser. For the 113pF, I used a 100pF // with a trimmer. For the 2k, I used a 2k21. For the 12pF coupling caps, I used 22pF.
I have a James Millen Grid-Dip meter model 90651, serial number 16. Released in 1949. Shown with the 6.4-16MHz orange coil. The trimmer was set to provide a dip at 14MHz.
Tank was then attached to the Lite. No calibration was performed. Measuring Q with S11, 13.290M / 980k = 13.56.
Obviously, a swag at best but I see no reason why anyone couldn't follow this paper and replicate the test with the low cost VNAs.

Just to give some idea on the error, assuming the RLC meter and resonance frequency of the Lite are close (which they are) 1.055uH @ 13.29MHz gives an XL of 88.1. From this we can calculate C at 136pF. With the 2k2, we should have a Q of 25. We came up with about half that.... Lots of error compared with the paper, but again no calibration and our coupling network is a bit off...
