Transmission Destroyed By Python 871xp

You're not butting in () too late for me . . . I'm still learning and I appreciate the information. This is not my area of expertise and I'm evaluating the information as I read more about the topic.

Looks like the 'connector' topic has reemerged, eh? I wasn't quite satisfied with the apparent resolution from the last round. Or stated another way, when is the last time you saw a cable installer whip out their soldering iron when connecting your cable TV? The connectors on mine have to pass a lot of bandwidth with both digital and analog signals residing on the same line (e.g., multiple computers and TVs connected to the same cable feed). No problemo with their crimped connectors. Yes, but their connections don't vibrate you say. Well, what about those in California? Do they solder their connections there? OK, more seriously, the satelite trucks carrying broadcast-quality HDTV signals use the same crimped connectors!

I first started using crimped connections for some applications in the 1980s. I had previously soldered the amphenol pins used in my DB-style connectors on computer serial and comm ports. I was skeptical of the newer, crimped-style connectors and refused to use them for a long time. Eventually, I tried a few and they seemed to fail quickly. I then invested in a high-quality crimping tool (around $80 back in the 1980s) and learned to crimp 'properly' (i.e., practice, practice, practice) -- I eventually got it right. It worked for carrying these sensitive high-speed computer signals, so I suppose when done properly it should also work with simple automotive 12-volt applications. (FYI: I don't actually use butt connectors, but rather the C-spade type for making connections in my vehicles that might later need to be disconnected for maintenance of the installed device. I also use heat-shrink tubing including the fusible type.)

RE: Soldering solid wire. Gee, I don't seem to have a problem with this in carrying high-speed digital and analog signals. I would suggest reading the 12-volt's discussion on "how to solder" to improve your technique. Solid wire is the standard for on-board computer circuitry and for most experimental devices prototyped in state-of-the-art research facilities. Stranded wiring is used with stressed or some high frequency devices.

What (some? many? most?) automotive installers consider a soldered connection would be marginally acceptable in my research applications (yes, I saw the 'connections'). They are simply poor, high-impedance connections done without proper training in electronics but which usually suffice because of the simple nature of most automotive signals. I'm not sure that these same installers would be able to properly use a crimping tool, but in some ways that method is a bit more fool-proof than the poor soldering technique that is commonly used in 12-volt automotive installations.

Finally, I've sure that the aviation industry has lower standards than the automotive industry.  This is like telling me that the reliability of DEI devices is better than NASA's quality standards and defies serious comment.

Have a good day, eh.

Not really being a DEI fan..... I love this statement.   But I am learning. Astroflex (DEI of Canada)

I have never had a bad dei product, but I have seen two space shuttles explode...

My research is done. NASA can't design ANYTHING. PSSSSSH... Rocket scientists...
