Doug,
As Mel has suggested a laptop supply is an option, I used one to power my K2
in RX mode 24/7 over a period of almost 3 years during a propagation study.
The supply I used outputs 15V @ 500mA, so I used a LM317 regulator after the
supply to obtain the required output voltage for the K2
Hum?

Is there any reason why I should NOT use this as the PS?
Hmm... 12V at 500 mA is only 6 watts-- perhaps the 14 watts
refers to the power drawn by the wall wart while supplying rated current.
If that's the case, then I

Most of the wall warts are just rectified AC. Very little if any
