[Elecraft] 6 m reception comparing with KX3

[Stephen Prior]

Skip,

I can hear no difference on FM between the K3 and the KX3.  1uV from the
XG3 on 50.120 MHz gives much the same level of smooth noise from both
radios.  My KX3 is #434 so yours is not an 'age' issue,  there must be
something else wrong.
