[UK-CONTEST] PL259 Connector loss

[David]

Ian

I teach the intermediate course how to solder using a PL259 of the worst
type and show them how to do it by using a file and a drill. File the
plating off near the hole and slightly enlarge the hole by drilling it out.
But I also teach them to tin the braid on the coax and cut off the access
braid. This makes soldering the plug on to the braid easier.

I demonstrate by doing one end of a short length of RG213. They do the other
end to prove they have learned the lesson and can do this part of the
course. They get a good patch lead for their shack.

Having done the above, I then show them a braid clamp type and tell them to
only ever use this type.

I agree the silver plated connectors are the best solder type. I understand
that silver plating has lower IMD than nickel plating. Probably the
difference is not material on receive but may be some one knows better than
I?
