[Elecraft] Power adapter for KX1

[Eugene Worth]

Ladies and Gents:

I am thinking about getting a KX1 kit for a mini-DXpedition to Bonaire (PJ4) early next year. I think that and an Array Solutions PS-12R1A wall wart power supply plus an EndFedZ 40/20 antenna should be a nice little package that will easily fit in a backpack. That power supply should get nearly all of the 4W output as well. The primary reason for going is SCUBA, but you can’t dive all day/night … 

Long story short, I also have a Ten Tec 506 Rebel. I can use the same PS on both if the adapter is the right size. SO, what is the adapter size for external power on the KX1 … I think that’s part J1 in the schematics. 

2.1mm? 2.5mm?

Thanks in advance. I’ve looked at the KX1 documentation. I can’t find anything except “J1" … and no post size.
