[Elecraft] K2 using the PA xmit RCA jack output for AUX VDH out

[Don Wilhelm]

Duane,

Although you can certainly do that, I would suggest that you do not.  If 
your K2/100 were ever sold, the buyer would expect that jack to be wired 
in the normal manner.

If you want 12 VDC for accessories, I would suggest that a RigRunner 
would be a better solution, or wire an in-line jack on the power cord.  
CAUTION, the extra jack would have the full current potential of your 
power supply, and should be fused with a fuse size that is consistent 
with your accessory and the size of its wire.  Running high current DC 
into a small gauge wire can cause molten metal to fly in the event of a 
fault - think safety!
