[Elecraft] K3 loss of rx signal

[Edward R Cole]

Simple - use something better than PL-259's:

I mainly use N connectors for low loss/high power and BNC for low 
power inside the shack connections.  I also have TNC and sma connectors.

Most connectors need a 1/4 turn beyond finger tight for reliable 
connections.  Sure cure for loose connectors is heat shrink over 
them.  Not only seals from wx but also loosening due to vibration.

Want to see what vibration does?  Install a radio in a D8 cat without 
some kind of vibration damping.  I did long ago, and the Motorola 
100w VHF radio was a cabinet full of loose parts after 8-hours 
running of the cat.  Wonder why military radios are full of glyptol, 
or completely potted in plastic?
