@craigwall9536 Radio receivers in WW1 could not be detected by the enemy for their IF emissions! It was the antenna that might have been observed. Far more interesting were the transmitter locations. Any non-ohmic conductor or junction is a semi-conductor, that includes, wood, clay, ionic liquids, gases, semi-metals (As, Ge, Sb) and insulators. Only some metals are "true" i.e. ohmic conductors, in that they follow Ohm's Law.
