Question

[Dave Reynolds-5]

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

The two receivers (main K3 receiver and optional KRX3 second receiver) are
identical and neither one has good "BC coverage" by itself.  If you want
good reception outside the Ham bands, add the KBPF3 to either or both
receivers.

What do you mean by "switch sepatate antennas between the transmit and
recieve with reciever protection."?  The basic K3 has one antenna port.  It
is used for both RX and TX with the receiver protected during TX.  If you
want to switch the receiver(s) between a dedicated RX-only antenna and the
TX antenna, add the KXV3.  If you want to switch both the transmitter and
receiver between two antennas, add the KAT3.

Both receivers have exactly the same spec and they only have BC if you add
the KBPF3 option to them (for both receivers to have BC, you need too
KBPF3s). Yes, they have isolation - although the KRX3 (2nd Rec) is not yet
available for people to have experienced that.

But one should not hope for real duplex as I understand. Second RX input is
grounded during transmit.
Even when TX and RX are using separate antennas and are on different bands.
