even this picture can tell a lot,and there is nothing more than your circuit with some modifications,oscillator+toroid and a tuned RX coil...
Morgan, each time you upload various picture relation to other pictures about your PDK ????!!!!!!!! Only all boxs similar, one picture with OO coils, other picture with one coil.
May be one is PDK 2.1 other is PDK2.11 and other is PDK2.111!!!!!!!!
