Being in an ocean environment with marine installations we normally solder
the center pin, just because. With the crimped center pin I have seen
failures over the years.
Even with the crimp there is a small hole for soldering which I do. Some of
the off shore LMR400/600 connectors are beyond atrocious, with crimp
sleeves that don't conform to spec, center pins that fracture etc.
I suspect that's the real issue - crimp connectors are great, when the
connector and tooling are right. Solder can fill holes and gaps. So
overall, in quality from best to worst:
1) good crimp, good tooling
2) soldered
3) crummy crimp, crummy tooling
It might be interesting to look at current US Navy practice for seaborne
equipment. In planes and spacecraft, it's crimp where possible.
MIL-DTL-28840E is the shipboard circular connector, and uses crimping
for the pins (sockets).

We have done away with clamp connectors for obvious reasons.
Salt air has an inherent ability to corrode everything, even in a wheel
house an IC-736 which should not have been in there that was pretty much
done.
With the exception of our mountain installations, at times we don't solder
the center pins.

Tony -
That's exactly my question for those who insist on using PL-259 crimp
connectors that require soldering the center conductor.
Crimping the center conductor takes about 30 seconds and I've used crimp
connectors that allow crimping of the center conductor for years without
problems. I can't even find my soldering iron in 30 seconds, HI! I can
even replace a coax connector on the top of my 120ft tower, even in the
wind, without running a 300 foot of extension cord or digging out my
propane
fired soldering iron.
I'm guessing that "solder the center-pin folks" have just always done it
that way and just feel comfortable doing it that way. That's fine, but I
think practically none of these people have tried crimp connectors with the
ability to crimp the center conductor.
This is one of those controversies, like "is a quad better than a Yagi",
that will never be resolved.
Personally, I'm glad not to have to find my soldering iron every time to do
what is a simple process with the center conductor.

A few years back I switched over from soldered to crimped PL-259 connectors
whenever I need to replace or make up a new cable. The connectors I buy are
for crimping both the shield and center conductor. Why would I want to also
solder the center conductor after crimping? What does that buy me? Doesn't
that defeat the reason for buying crimp connectors - ease of installation?

According to the specification the center pin is soldered, so DO NOT
Attempt
to crimp the center pin.
Purchase some proper coax prep tools it will make the easier and more
consistant.
DX Engineering sells the prep tools, crimpers, and connectors. Be sure to
use Amphenol connectors with the correct part number for the cable your
using.

I always put a little flux on the center conductor before I crimp it,
then solder.

I use the DX Engineering Ultra-Grip 2 Crimp Connector Tool Kit, the
DX Engineering RG-213 cable, and Amphenol 182102 no solder crimp
connectors (both shield and pin are crimped - no soldering
required). This combination has provided beautiful results for me
without any problems. I will never go back to PL-259's that
require solder.
Amphenol UHF crimp connectors from DX Engineering are reasonably
priced but can usually be found at slightly lower cost from the
major electronic parts suppliers.
