[Elecraft] Type "N" connectors

[Stan Rife]

The circuits that are not on fiber still are wire wrapped David. If it leaves the office on copper it is either wire wrapped or soldered at some point. The phone company here abandoned soldering a long time ago. We still have some frames that are solder lug equipped, but most have been converted to wire wrap.

  The telecommunications has been crimping, in some cases (such as power 
and ground connections) for a long time, and in others (such as BNC's 
for DS3's) for the last 5 years or so. Incidentally, just about all the 
T1's/DS1's in this country (at one time) were all wire wrapped.

Now I think we should get a discussion going about stitching cabling vs. 
tie wrapping. (Just joking, a little flame bait left lying around)
