[Elecraft] Soldering a PL-259 connector

[Jeffrey Wolf]

Regardless of the method of soldering a PL-259, before trying to flow 
solder through the holes in the connector, use a file on the surface 
surrounding the holes and even in the holes (you can use a small reamer) 
to break the surface finish and roughen the area. Be sure to blow all 
metal flakes out of the connector when done. Solder will flow much 
better than on the slick surface if you do this.
