[Elecraft] K2 12 volt power jack for amplified speaker?

[W3FPR - Don Wilhelm]

Tim,

Operating an external amplified speaker from the K2 internal battery will
work, but the amplifier will likely draw as much current as the K2 receiver,
significantly shortening the time you can operate on the internal battery.

If you really want to install an accessory jack, I would suggest using one
of the transverter holes in the top cover for the jack.

A suitable take off point could be at the cathode of D12.  There certainly
are others, but that one would be easy to implement, and should cause no
harm other than the extra current drawn from the battery.

73,
Don W3FPR
