[Elecraft] K3 second receiver

[adamkern at uchicago.edu]

I'm trying to understand the major intended uses of the
optional K3 second receiver.  My understanding is that the
audio out from the second receiver will be cut while the K3 is
transmitting.  Is the IF output port switchable between the
main and subreceiver?  In other words, can a panadapter be fed
by the subreceiver with wider filters selected than the main RX?
