6i1P(6AJ8)Single AM Transmitter testing in science lab

In physics education, Fox Hole Radio is still important subject to learn how AM radio working. However AM broadcasting stations are decreasing and the radio wave itself cannot be received in class room for the school building shielded electro magnetically nowadays. That causes the experiment difficult. So I made a bit stronger AM transmitter with 6i1P, 6AJ8 compatible converter tube, and tested in my school lab, to check the radio wave could reach from the next room so that they could understand their products, their handmade Fox Hole Radio, really catching the radio wave in air.
