The center pin on one of the connectors is shorter than it should be, is 
a possibility.
I have seen this more than once.  The pin is almost long enough to touch 
but not tightly.  When there is an active signal, i.e., the radio, there 
must be enough capacitance coupling to broadcast, but the mV of the 
receive signal isn't enough to bridge the gap.  At least that is my theory.
