I've read this: http://www.elecraft.com/manual/KX2%20FAQ%20v-1-2.pdf and see that a 12-14v power supply will work, but is there a recommended power supply (110v, US) to use on the KX2? Any ps's in particular to stay way from? -- W2KAP In any given circuit, the most expensive part will always sacrifice itself to protect the fuse.
