Right you are. My mistake. I don't have any transmitters of that era in my collection, though I do have the remanants of a 100-year-old coherer receiver, and a complete WWI U.S. Army SCR-54-A (BC-14-A) crystal receiver. The latter was designed to receive signals from observation aircraft transmitting on a BC-15 spark transmitter.
