[Elecraft] Possible K3 Antenna Input Leakage

[Ron Schwartz]

I recently completed a K3/100 kit (great experience)!  I have noticed a sizeable leakage between the ANT1 and ANT2 inputs.  On 20M, signals appear on ANT2 when there is no antenna connected, about 4 S-units below the level on ANT1 (where the antenna is connected).  On 40M the difference is slightly greater.  Just wondering if this is normal?  Perhaps I did something wrong when building the kit.  The radio does have the KXV3A RX antenna interface option installed, but not the sub receiver.

Thanks, Ron
