RX in and out questions

[tomb18]

Hi,
I am planning to get a DX Engineering NCC-1 noise cancellation system and just want to be sure that I understand how the RX in and out works.
If I press the RX button on the K3, does this effectively just break the signal path on the selected antenna allowing a different antenna to be used on RX-IN?
If you jumpered RXin and RX out together, would it be the same as if you had the RX switch out?

I just want to be sure that if I put the NCC-1 in this circuit then I would be using both my regular antenna for receive as well as the noise antenna.

Thanks, Tom

Hi Tom,
Pressing the RX button switches the receiver to the RX-IN ant. If Rxin
and Rxout are jumpered RX Ant in and out would be the transmit antenna.
There is a block diagram on my website that might help you understand
it. See
