Sirius XTR1 gets VERY hot - normal ??
 

I use a Sirius XTR1 receiver in the XACT boombox and car adapter. The
XTR1 (shown here http://tinyurl.com/87cvu ) gets very hot to the touch.
Is this heat dissipation normal? It has a lot of vent holes so it
appears it's designed that way.

Does your Sirius XTR1 radio get very warm ? If so, any idea why ? Does
the LNA or other circuits cause that ?

Thanks, Greg

My Kenwood Here 2 Anywhere also is hot to the touch.

I wonder what causes this heat in satellite radio units. I make
semiconductors (chips) for a living, and none of our chips run that
hot. Perhaps it's the power supply, but why would they design it that
way?

Anyone have a XTR1 or other radio that gets pretty hot to the touch?

I'm not sure what the model is, but a friend of mine has the Kenwood
Plug-n-Play, and it gets disturbingly warm. I think this is one of the
reasons why satellite radio isn't wholly portable yet, because the chips
used consume a lot of power (and release a lot of it as heat). Next
generation chipsets should be a lot better.
