[Elecraft] KX3 and Heatsink

[Julia Tuttle]

Yeah, what Eric said. Elecraft says, in the "Output Power" specification:
"5 W or less recommended for high-duty-cycle modes (FM, AM, DATA). Power
will automatically be reduced if PA temperature or current limits are
exceeded." The stock heatsink is generally adequate *within* that
recommendation. If you'd like to *exceed* it, you'll benefit from an
aftermarket heatsink. I have the "ultimate" ProAudio one as well, and it is
generally adequate up to the max power output of the KX3 (10-15 W) on
high-duty-cycle modes.

73,

Julie
