Hi all.
did anyone of you ever keyed a sparkgap-TX with coherer
as RX, not to forget the railway-tapewriter and Wagner interrupter!
I - born in 1928 - had the opportunity (back in 1939) since
we (mis-)used a Tesla-Setup for it at high school.
Covered distance: 10 meters, BUT with a wall in between. ;-)
Suppose it was quite illegal, and still wonder why our teacher
didnt get into trouble with the - than rather strict - authorities.
Amazing experience, (you bet); unfortunatly the whole gear
(and pics of it) did'nt survive WW 2.
