Hey Mark,

Email reflectors are read by people with a wide variety of email software. 
Because I subscribe to a lot of public lists, I purposely use email software 
that I can set to avoid viruses and other security threats. Part of that 
strategy is PLAIN TEXT. 

Many list members live in rural areas where they must download email via a 
dialup. Others live where they pay by the byte. Your email is nearly three 
times the size it needs to be, thanks to all the formatting. 

Please set your email software to send PLAIN TEXT. There's so much formatting 
in it that it's unreadable. 

73,

Jim K9YC

Steve:

With regards to the center conductor expanding if it is cut after removing the 
dielectric, I have noticed this with 9913F7 as well.    Is there special tool 
or technique that can be used to minmize this ?

Best regards
Mark

Hi Roger,

The ctr. cond. on LMR 400 (solid)  and 400 UF (strnd'd)  are both .108; 
however, cutting the ctr cond of the stranded  400 
UF  , AFTER removing the dielectric will expand the OD....and sometimes dealing 
with the stranding anyway will cause it to 
expand a bit .
  Ref. whether  crimp pins vs. clamp pins are different:  for the most part 
they are different, in the below around .500" OD 
cables; however, some mfrs. do have a few sizes and types that they are the 
same.
  Ref. soldering crimp type pins:  in production modes, crimps are just crimped 
due to labor time/cost, but in less than 
production line app's,  I , and many before me, recommend a little added 
security (electrically and mechanically) by 
soldering the center pin of crimp types, after crimping.
  As many other things, "a little of everything is involved"... not cut and dry.
Bottom line: for most ham use, crimp or clamp:  both are very good 
mechanically, when done right and not hard to do it 
right.    Crimps are less aggravating and we have excellent tools to use at 
less than $ 40 for the tool, $ 23.50 for multi 
cable die, and this tool is one of few out there that will let you change the 
die.  I've used the best commercial production 
tools and this one is fine even for repeat production...ratchet release at 
proper torque on die, etc.
  And Roger, you are a testimony to a "satisfied crimping ham"  HI
