[Elecraft] K3 loss of rx signal

[Phil Hystad]

Don,

In my experience, PL-259s do not get tightened properly when the little teeth on the end do not engage properly.  So, when I tighten PL-259s, I make sure that the teeth fit in together properly and this always gives a snug fit.  Note: I am not sure if these are called teeth or not.

In almost 60 years of dealing with PL-259s the only time I needed pliers was to undo the PL-259 connector that I had on my truck that had sealant on it (it was very much in the weather) and stuck besides.

Then again, I don’t ever remember having any loose connection problems with PL-259s either.
