Bob,

You would be surprised what fans can do ref vibration.

Actually I view it as "incorrect info". Most hams in fact do not have a
proper crimping tool. They cost quite a few dollars. I have a good idea as
we used them in our manufacturing processes and they average $45
and up......way up! So we hams use what ever is at hand, be they the
VACO multipurpose tool that sell for $4 to $5. Or we likely don't have the
proper die for the connector should we have a crimping tool.

I'll take my chances on my crimp and solder process as to opposed to any
crimp method. After all, there's little to no vibration to ever exist
with my radios and power supplies sitting on the desk. I don't consider
#3 or #4 to be a concern.

My take is that the sentence in the last paragraph "It is absolutely
necessary that the proper tool be used for the connection being crimped. If
you are going to use a crimped connection it is imperative that you have a
tool that matches the connector. If you do not have the proper tool then DO
NOT use crimped connector." negates your reasons.
So if one can't crimp, what's left? Solder.

I would agree... I crimp most every thing now. The cost of GOOD crimp
tools are reasonable priced...

BUT, a year or two ago, I found crimp lugs I was using on my ladderline
were making intermittent connections and I was having a difficult time
finding the problem.

The crimp was not working with copper coated steel wire... The steel
wire does not compress. Soldering "might" have helped, but I went to
bananna plugs with screw compression wire connections I can re-tighten
as needed...

Hi, we closed this thread last week. There is also a ton of past searchable info
on APP connectors, crimping vs soldering etc. the list archives. See:
