So it looks like this particular design is feasible and the loop construction not very critical. I have not tried this particular configuration (my loops need to incorporate some selectivity to be viable, due to the 10s of volts/metre from the broadcast stations), but I used a similar approach with the bandpass loops and several other designs, and got more or less what was expected, so it should work OK.

Dear James,

  many thanks for your considerations and the computations done on the 
configuration
I proposed. They are much useful and appreciated, exactly up to the point, as 
usual !
I will try to do some experiments during the coming month of August, if the 
temperature
and, more important, the percentage of humidity will allow me to do some work 
in the
garden ! Just now, it is too hot and too damp to do anything...!
