[Elecraft] laptop power supply to power KX3

[Fred Townsend]

Jeff, caution.  Laptop power external supplies are designed to be followed
by precision internal regulators that handle the logic voltages and charging
the battery. The external supplies are not well regulated and can be quite
noisy.  They may not be the best supplies for ham rigs.

While at work I went through our stock of power supplies for the various
makes of laptops we use.
I found that Toshiba supplies are specified 15v and ranged in current
capability from 2.5 amps and up.

Dell, Lenovo, HP, Acer, Asus all use 19v supplies.

Those Toshiba supplies are very small.
