Ok, now that we have had a chance to look over the exterior of the SDR 1000D, let's remove the top cover, look "under the hood" and see what makes it "tick."
As you can see the printed circuit boards, (PCB's) are mounted in a horizontal, "sandwich" style configuration, with the largest of the PCBs mounted on the bottom of the unit, and the smaller PCBs mounted one on top of the other.
With the fan being mounted on the front panel, air is circulated through and across each of the
PCBs from front to back. In the last two years that I have used the 1000D, I have had no problems related to heat. As a side note, I have noticed the Flex Radio has done the same thing, using the horizontal mounting approach on their 1500, 3000 and 5000 series Flex Radios.
Most of the internal wiring is well dressed, either between the PCBs, along the sides, and bottom of the unit, making it easy to get around inside if needed. The only major wiring which is run above the boards, is the power supply cables, that runs from the right side rear connector to the input of the power supply board as shown in the photo.
I will cover the function of each individual printed circuit board used within the SDR 1000D, and their operation and location of each board in the next post.
