Re: [TenTec] help in soldering pl259 outside

[Dave Haupt <w8nf@yahoo.com>]

If the PL-259s don't have silver-plated bodies, then you're struggling to 
solder to nickel.  Nickel acquires a layer of oxide that's difficult to break 
through with flux.  Get a small enough steel-bristle brush that fits inside the 
connector body, and scratch it up thoroughly where you are trying to get solder 
to flow.  Do the same to the outside where the solder holes are.  It'll solder 
much more readily, with much less heat.  It'll take about 30-45 minutes for a 
new layer of oxide to form on the nickel.
