[Elecraft] K3/0 DC power

[Don Wilhelm]

Milt,

The K3/0 power input is the normal K3 12v power output jack.
Because this is an RCA jack, you might want to consider making an 
adapter cable that has a different jack (APP or other jack).
If you leave the RCA plug connected to the K3/0 at all times, there is 
no problem, but I do not like the prospect of having an RCA plug on my 
workbench with its exposed +12V pin.

As I said, if that plug is always inserted into the K2/0, everything is 
safe, but if you are in the habit of disconnecting the power plug to the 
K3/0, make an adapter and leave the adapter connected to the K3/0 - all 
that is my personal safety consideration.  Several QRP kits also use an 
RCA plug for 12v power input, so the K3/0 implementation is not that 
unusual.  Leave the RCA plug connected and disconnect the power supply 
end for safety.
