[Elecraft] K3 Sub Receiver and protecting the Sub RX input

[Ken]

Wayne,   can you please elaborate on what is sufficient antenna separation when a transmitter is operating on another antenna?   I ask this because my K3 returning from a trip to Elecraft after damaging the front end.   I assume it happened when I was testing an old boat anchor (Viking II, 100 watts) on an antenna 15’ feet away and parallel to the K3’s antenna.  How far is enough?  Yes, I realize that’s probably too close but at this point I am concerned.   

I know the K3 is popular in Field Day and DXpedition operation so obviously it can work, but I’d like some guidelines.  

Thanks,

Ken WA8JXM
