Any experience with DX Engineering PL-259s? I bought a half-dozen crimp
type for RG-8X, on the theory that DXE would stand behind their own name
brand. They are even stamped with a DX Engineering patent notice -
like what's to patent? They feel a little lighter than WW2 surplus,but...

I consider this a fool's errand. The only connectors or adapters I
will buy at a hamfest are MIL-surplus or Amphenol-branded, and they're
sold by individual hams. I've probably used a hundred or more of them
over the years, all bought in lots of 50 or 100 from franchised
distributors as part of a group purchase that I or others have
organized for clubs to which I've belonged.
For more than 25 years, I've served on the Standards Committee of the
Audio Engineering Society, which includes representatives of major
manufacturers like Switchcraft, Neutrik, Shure, AKG, Neumann,
Audio-Tehcnica, Sennheiser, and Beyer Dynamic. (not Amphenol -- they
haven't been in the audio biz for 40-50 years, which Switchcraft and
Neutrik have dominated for that long). Over the years, I've seen many
reports from some of them about counterfeits of their products. With
microphones, the defects are sound quality; with connectors, they're
failure to properly mate, dissimilar metals that you can't solder to
or degrade with time, dielectrics that melt when you try to solder.
Yes, there are other mfrs of connectors, but I wouldn't go near them
unless I was a mfr who could vet the company, get samples, see their
quality control. Years ago, W2VJN did that for some antenna switching
products, and he got quality. Our chances of getting quality
connectors are about as good as winning the lottery.
When I got back on the air in 2003, I was ignorant of this issue with
ham connectors, and bought a lot of adapters to fill my junk box. Over
the next 5-6 years, they caused me untold grief trouble-shooting the
failures they caused in my station.
