WA9WFA 1929 Hartley CW Transmitter - copy

CW transmitter design by Scott M. Freeberg, WA9WFA. The 1:700 tapped transformer is actually suppose to be a tapped inductor with the antenna leads coiled around one side. I wasn't sure how to make that work using this simulator... all well. It works! If done according to the pdf link, it should be reasonant at 3550 kHz, and have tuning capability with the 150 pF capacitor being variable. Give your phone a shake to inject noise after keying down the keyer switch. 

It's definitely a work in progress. Suggestions are welcomed.
