[Elecraft] Spark gap hisory

[John Cooper]

Sorry for off topic.  Been researching some radio history.  Did old time ship spark gap transmitters have high voltage on the key itself?  From what I can tell it looks like they used a battery to the key and then made high voltage in spark coil or induction coil?  I'm assuming this would  of have been a step up transformer?  If anyone knows about this stuff I had some questions.
