Hi Carsten,

can you post close-up pictures of what's inside?

I suspect the triangle at the loop to contain the amplifier and the box just to contain the batteries, a remote tuning potentiometer and a DC supply circuit. Is that correct?
Is the loop tuned via a potentiometer and a varicap diode or by a variable capacitor? Does the cable from battery box to loop contain 3 wires (ground, tuning voltage, RF-signal)? Does the amplifier look like a single-ended or a differential input type? Is it made of discretes or an IC?
