[TenTec] Connector tightening

I always change the PL259 out to type N.  PL259 is not a 50 ohm connector and leaves an impedance
bump on the line.  That connector became the default connector after WWII but is somewhere around
93 ohms.  That's why I change them out, not to mention that they have a way of backing off a bit.

Use a wrench to get another 30 degrees????  Why not weld the coax to the radio and be done with it?

Oops...I meant PL-259, not 255
