Hi Nicolas
I'haven't designed this pcb for this purpose, but I used an older pcb (that I designed as antenna for another Lrl) and at the beginning I wanted to build a RF sniffer in FM range as front end stage of my Lrl. This circuit works well as lrl but not as amplifier but as oscillator. I post here again my pcb where the pcb is also in its real dimensions. I have not really measured the capacity between strips. Try (with your pcb) a small capacitor ( 1 pF or less ) between TR3 collector and TR1 base, perhaps maybe you'll get lucky and can get an oscillation.

Best Regards
