1. 1000 feet of #40 gauge enameled copper wire will be needed to rewind the coil in the Shadow Meter assembly. It just so happens that #40 gauge wire has a resistance of about 1.1 ohms per foot. So in a typical radio, a current draw of 10ma. will give the 10 volt drop across the coil that it takes to operate the shadow vane correctly.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
