This units selectivity is far better than you would expect to find in a crystal receiver and volume is equal to that obtained with a transistor. No external power source is required. The unusual selectivity of this radio is due to its special double-tuned circuit. 4b族元素WebThe MOSFET 3SK143-Q is not “zero-voltage-threshold” but very close to, so it still can detect very weak signal and have superb selectivity in the crystal radio. Another advantage is that the output impedance of 3SK143-Q can be as low as 1 to 3 KΩ (the ALD110900 is about 25 to 50 KΩ), so you can directly connect the low impedance headphone ... tatrajahu
