[Elecraft] K3S QST Article

[Wayne Burdick]

Our entire product line emphasizes portability, so we'll just have to continue the never-ending search for 12 volt mojo. (Note: the new Upgrade is a case of this; IMD is improved when running from lower voltages.)

Stick with Elecraft and minimize your carbon footprint!
