[Elecraft] Laptop Power Supplies

[Steve Kavanagh]

My old HP supply is marked 18.5V 3.5A.  My wife's newer HP is 19.5V 2.31 A.  The two DC plugs are very different (not sure how to specify them).  that could be an interesting product.  Mind you, experiments have shown that my laptop creates a bit of RFI from every port (USBs, audio etc.) and the screen, not just the power supply. But every bit that is quieter ought to help.
