Probably be easier and cheaper to get a wall wart from Radio Shack or
any electronics dealer - doesn't have to be AC, as any DC supply of
11-16VDC/200 ma or more will also work, and plug polarity does't
matter because the power jack goes to an internal bridge rectifier.
Looks like the plug size for the rear power jack on the keyer is
5 or 5.5 mm OD/2.1 mm ID. If you run your xcvr with a 13.8VDC PS,
connect the keyer to that (with an RF line filter at the keyer) and
save buying a wall wart.
