</span>How did you measure the voltage while connected to the HDHR, and what<br>
was the HDHR doing at the time? Is your meter fast enough to capture<br>
the minimum voltage over a time period?<br></blockquote><div><br></div><div>The HDHR wasn't doing anything, but it shouldn't matter, if at whatever current it's pulling, it's seeing 5.17V, then that should be sufficient for the Ethernet chip. If under heavy tuner use it dropped down, then I would not be surprised if the Ethernet dropped out, but that's a different failure mode.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I think you're better off using a simple resistor to load the supply<br>
