Although an interesting design, although I note that it has no input low pass filter network.
This has two implications.
It makes it (and any receiver that may be connected) susceptible to interference from strong FM broadcast stations.
The amplifier input impedance will remain low, and not track the loop feed point impedance as it approaches resonance. This will result in less than optimum performance on the upper HF bands.
I believe both problems could be solved by adding a suitable filter network.
It will be interesting to see how well it performs relative to an LZ1AQ or Wellbrook, especially considering the additional complexity.
