Half-kilowatt spark transmitter “3CS” from 1919 to 1922, equipment is all home built, called it “Big Bertha,” receiver is regenerative 150-700 meters with Moorhead Audion Detector and 2stage amplifier. Commercial marble base key and Baldwin phones.

Amateur radio-wise, Ed having passed through all the various stages of spark transmission from 1⁄4 inch spark coil to the booming 1 KW sync-spark set in the middle 20’s, he finally saw the light when a little 7 l⁄2 watt tube began to run rings around his “Big Bertha.” In late 1924 he gave in to the less noisy tweet of the CW signal. Then came the 5 watt “Colpitts” and “TNT” circuits, with basketweave coils and honey-comb tuners, all of which led up to the present pretty desk-top gear of today (1961).
