[TenTec] Heatsinking and fans....was: Pegasus - horizontal operation?

[jesser@amtelcom.com (Jim Esser)]

I've been following this thread with interest and have implemented all the
improvements on my Argosy II  (Bigger heat sinks, muffin fans, heat sink
compound, switches, etc).

Now my only problem is that I have to turn the rig off every hour or so to
let it defrost so that I can read the display.  I am considering installing
a hair dryer on the Argosy to keep it warm.

          I added a small thermal switch rated at 135 deg F. to the heat
sink of
        my CORSAIR II and a small DC fan.  I have noticed that the normally
open
        ( N O ) contact only close on long CW transmissions.  I found the
switch
        at AMERICAN SCIENCE AND SURPLUS in Milwaukee WI for $.50 / unit.
