[Elecraft] loss of RX sensitivity

[Bob McGraw K4TAX]

Yes, regardless of how good they look, always snug the PL-259 with a small pair of Channel Lock pliers.  Finger tight is not good enough.   Many of our connectors today are of inferior quality.  

Also due to the use of jumpers, the flexing and pulling is prone to damage the connection between the coax and connector.  Always suspect the jumper and icon doubt, replace it.  AND if you find one defective or in question, immediately cut it in two pieces. Thus it won't be used or confused again.

What IS correct is that 1) the connectors must be properly installed both to the coax and the equipment, and 2) that the shell must be well tightened, often described as "wrench tight," with the pins on the PL259 firmly seated in the notches in the mating connector. I'm being generic about mating connectors because it's equally true of SO239 and other connectors like barrels, elbows, tees, and inter-series adapters.
