Rectify radio output with diode and capacitor. Run Joule thief from capacitor. You will need at least 0.5 to 0.7 volts to run Joule thief. You do not need 10,000 uF capacitor, use what ever you have. Reduce resistor value to make LED brighter.

Same circuit with toroid >> 2 uA Joule thief - YouTube
