[Elecraft] K3 12v RCA rear socket.

[Don Wilhelm]

Peter,

There is no 'setup' for the AUX 12V output - I think yours is broken.
If you want to make some measurements, take a look at the lower right 
corner of RF Board schematic sheet 3.  The RFC and resettable fuse are 
thru-hole components, so troubleshooting should be easy.

I've perused the instructions and Freds book but cannot see if I have to enable this function. Its either that or the socket is defunct. I put the K3 together about 4 years but have never had the need to use the 12v RCA output before.
