1910 radio, crystal set

[vintagecollect]

I just got a 1910 pat. date radio coil, married w/ a 1915 heaphones, w/ a solid state diode for better performance. Volume is medium, even loud somewhat depending on skip at times where headphone can be placed away from ears and still be easily heard .. Good earth ground and antenna coupled near one of the sets wires I believe produce a regen. effect to make station louder. A six to ten ft. antenna wire is all that's needed. CAN anybody show pics or plans to make a 1910 galena crystal detector setup? What does the double detectors do like in early AK sets???

DOES anybody here have a pre1919 or 1918 set here? Info is hard to find. NICE forever set, nothing to fail.
