Craig Pitcher Spark Gap Radio Collection

CHRS Member Craig Pitcher shows his wireless (spark gap radio) collection to fellow members Bart Lee, Jaime Arbona and Mike Adams. Wireless was two-way messaging used between 1900 and 1920, largely between ships at sea and shore stations. In the beginning it was coded messaging, later radiotelephone or voice.
