K2: Almost think I might have licked the little buz fan

[dw-4]

Just for kicks I fabricated 6 aluminum fins 2" high and 5.5" long out of
.06" aluminum.
Pinch fit them every other rib on the right hand top of the K2 heat sink
using a touch of arctic silver heat sink past.

Ran the unit at full tilt for 2 hours worth of rag-chewing.
Checked for heat with my hand every qso and found the top just barely
got warm every time.
The little buz fan never made a peep.

Its ugly fer sure!
But so far, its 100 watts of pure silent qso-ing.  :~]
