[TowerTalk] DX Engineering

[Thomas Noel]

John,

There was nothing wrong with my technique.

Since it hit the TowerTalk listserve again yesterday, I was nudged to find an answer. I cut another of the DXE-8XDX006 jumpers in half, prepped the cable as per their instructions. The center conductor measures 0.055 inches just as it should. Nothing wrong there.

I then used machinists’ drill bits to measure the center conductor hole in the Amphenol 182115-10 connectors shipped to me. The center hole will not pass a #55 drill bit which measure .052 inches. It should be able to pass a 1/16” bit (.0625”) as the spec calls for .063”.

So the problem is a batch of the Amphenol connectors which appear to be out of spec. Interestingly, I bought another batch from Dave’s Hobby Shop on EBay, and the measurements are the same. The connectors are not marked, and could be a cheap knock-off.

Interesting learning experience. I don’t think this was something within the control of DXE.

Let it die.
