Hi all,
I had some trouble with the 700 vc router I just built. Luckily, Paul was
available for some live tech support and I got it sorted out. Because the
problem seemed like it ∗could∗ conceivably happen more than once, I'd like
to tell you all about it.
The way the coax attaches to the jacks, the braid is pulled to one side
first and twisted. On a particular strand of coax, the inner insulation had
melted or been cut through (very fine break) and the braid was resting
across it, causing a short. I couldn't see this at first and went through a
lot of trouble disassembling the PCB sandwich, etc.
So if you're having trouble, don't forget to look at the easier solution
first. I had carefully scanned the PCB twice, including verifying component
placement, before I looked at the other end. And considering the iron
proximity we have to work with sometimes when wiring the front panel, it's
fairly easy to slip and melt a bit of insulation.
David.
