[Elecraft] K3 loss of rx signal

[Jim Brown]

When that happens, the connector inside the radio is either of inferior 
quality or the installation method is wrong. A PROPER chassis-mount 
female UHF connector either has four mounting screws to prevent it from 
rotating . While there are also connectors without those mounting screws 
with a square side to their circular body, they must be mounted on a 
chassis with a hole of the same shape, and the chassis must be "hard" 
enough that the connector cannot rotate. Any connector that rotates when 
pliers are used to tighten or remove a mating connector is WRONG!
