Re: [DW4000] Signal strength drops from 60 to 10 every few hours
said by rlwpub  :Did I read that correct? And could that be causing a component to over heat? The 6 extra volts? No, you didn't. To receive from a vertically polarized transponder, the IDU sends ~13v to the ODU. To receive from a horizontally polarized transponder, the IDU sends ~18v to the ODU. Unlike satellite TV which switches polarity almost as often as you change channels, sat internet is usually one or the other: vertical all the time, or horizontal all the time.
The installation instructions and user manual are VERY clear about providing max air flow to the IDU and power adapter. Sticking either/both away in a drawer or closet just won't work. Most DW4000 users discovered long ago that the best position for the IRU/ITU stack was to rotate them 90 degrees (set them on edge, rather than one on top of the other). Some even removed the clips and set them end to end (also on edge). The power adapter should also be exposed to circulating air, the best position would be for it to be sitting on edge also - one of the narrow sides. This will maximize exposure of the surface area of the case, permitting it to act as a heat sink
