- Editor's Notes
- We find many defects in our work. After working all day yesterday and all night we find one of you induction coils is so badly insulated that we can hardly get any talking over it. If you will copy the cup in the transmitter as made by the W.E. Mfg Co you will improve the loudness greatly. We find upon testing your primary wire that he resistance is only 17/100 of an ohm whereas it should at the lowest estimate be 40/100 of an ohm.
