[TenTec] Jupiter Cooling Fan?

[Gary Hoffman]

My experience with the Pegasus is that in PSK - a very efficient mode -
the heatsink stays acceptably cool.  However in RTTY where I have
to run it full blast, it gets HOT.  I also use an amp in RTTY mode, and
I tripped its overtemp out.  Thus I had to add a second fan to the
amp.

As others suggested, I just set the fan on the table adjacent to where
I wanted the cooling.  I run it off the same power supply as the rigs, so
it always goes on when the rigs do.  But I only need it in RTTY.
