Perhaps this will help:
Start with all coils fully out.
Set final output vol knob to 3 o'clock.
Set all other controls as specified in the alternate tune method PDF from PAIA
Set L1 to a clockwise setting of 1, and a half to 2 turns clockwise in. (start work at 1 and a half, and adjust as needed).
Set L4 to 1 turn clockwise in.
Adjust L3 til your hear the false heterodyn of the volume antenna (sounds bright, and vol antenna acts like pitch only theremin.)
Back L3 off just till you hear it's tone go to airy hiss, (like radio noise).
Adjust L2 in until you start to hear the true heterodyne of the pitch antenna, at which point, you should get pitch aerial response.
The above is based on instructions provided by Scott Lee at PAIA.
Scott also mentioned that if you set an A M radio to between 800, and 900 Mhz, you can actually tune in to the heterodyning frequencies.
It beats using the gator clip, but it will get you close. I've still got a ways to go before I get full loudness at normal final output vol knob settings.
