[Elecraft] Question

[Dave Reynolds]

Hi All, I am planning on buying a K3 in the near future and just have a couple of questions, is the reciever in the radio have the same specs as the optional sub reciever with the exception of the BC coverage of the sub? I really don't care about recieving the BC stuff and from what I can see the reciever in the rig should do just fine as long as I can  switch sepatate antennas between the transmit and recieve with reciever protection. 
I would appreciate any input you can give me. I hope I have made my Q clear enough.

          Tnx es 73
