[HCARC] Crimped vs Soldered Coax Connectors??

Tue Sep 23 19:59:50 EDT 2014

But John - guys like Kerry and Eddie the Weather guy, and I am sure more 
will tell you/me that Amphenol or not, PL-259's are a far inferior coupler 
to an N connector.  Not only are they not waterproof, they are 37 ohm vs 50 
ohm for the N connector (why put a 32 ohm connector - really a number of 
them into a 50 ohm coax run that we have worked so hard to ensure stays 50 
ohms).  Much of what I am trying to get at here is for the new Ham (you know 
the Techs and new Generals - come on Tony Moore pass that Gen test on 
Sat,!!!) why shouldn't they start out using N connectors??  They have to 
invest in something and many will tell you the N connector is a better 
initial investment.  What I am hoping to do here is run a dialog on what is 
best vs what I/we have always done.  I used to have a sign on my desk in the 
Navy that answered for Junior Officers and even worse Junior Officers with 
their Chief Petty Officers in tow that said "Just because we have always 
done something a certain way, doesn't mean we haven't been doing it wrong 
all along - BE FLEXIBLE, LEARN!!".  I am just trying to learn - to be 
flexible - I am still so new that I have junior enlisted vs Commander 
Department Head level knowledge.

Might also be interesting to see what the Texas Army MARS guys are doing 
with their equipment.

And furthermore, the Reflector has been too darn quiet for far too long - 
lately it's beginning to be sound like 2 meters or 70 cm in Kerrville.  We 
need some controversy - stir things up a bit - that's my motto!!

I solder all my connectors, and use UHF PL-259, but only Amphenol 83-1SP.

A long, long time ago when I first got started, I was using cheapie hamfest
connectors. It didn't take long to see the error in my ways, especially when
it involved connectors on the tower.

Do yourself a big favor and spend the extra bucks.

Navy radioman here 76 - 82
We soldered everything, and if it was in the weather, we taped it, and
copper coated it

Never had a bad connection that way

Derrell,

I too am retired Navy (CDR, SC, USN-ret) and ran a number of Aviation Supply
Activities in the 80's and 90's.  That however, is (Heaven Forbid) 20-30
years ago and some procedures may have changed.  I understand the Air Force
has and I can easily check at NAS Corpus with the Supply Response Section
(SRS) to see if the Navy has too.  I am assuming NAS Corpus has an IMA level
maintenance facility for the training aircraft.  Might be interesting to
find out.

I taught aviation micro miniature (2M) circuit board repair certification in
the Navy back in the late eighties. The miniature course was five weeks long
and the micro was three weeks. The miniature curriculum was mostly high
reliability soldering along with circuit board repair. The micro repair was
very specialized with high power, stereo microscopes.  The Navy's avionics
have to "take a licking and keep on ticking" as John Cameron Swayze used.
Our aircraft  get shot off  the deck and hit hard when landing. Soldering
connectors is more reliable than crimping when done properly. Crimping by
definition is deforming.
