This is an operating reproduction exhibit I built of a 1921 spark gap transmitter used by Amateur Radio operator John Westcott, W8AGA. It was built for a house museum where John once lived and operated his transmitter, but the museum reneged on its agreement with the radio club and the exhibit was never installed.

Question to any one, these transmitted on a very wide band width, basically a blast of RF that splattered across a wide spectrum of frequencies. It was just a spark impulse. Thanks
if you get a chance, go see the titanic museum in branson mo. they have a straight key hooked up to a spark gap generator there for people to try out.
you can do, but whith higher powered machines the nead for spark quenching became greater, and thus the rotary gap came in, as can be seen in the video, it stretches as the disk roates causing it to cool down faster. they were used with AC and produced a more regular and much higher powerd spark. hope this helps
