Perhaps a daft question, but assuming that the DX is working SPLIT, that
I am NOT using RIT nor XIT and that I am listening to the DX with VFO
A. If I now want to listen to the calling stations which would normally
be done VFO B, which also controls my Tx frequency when listening to the
DX on VFO A, and then reverting back to VFO A to listen to the DX before
transmitting, if I cannot use VFO B for receiving and have to use VFO A
does this mean that when I call after finding a 'hole' I would then risk
transmitting on the DX's frequency? If I understand correctly what you
mean by copying 'the frequency' from B to A, would that not slow down
one's ability to change Tx frequency rapidly in a pile-up situation?
If your rig is in SPLIT you are listening to the DX on VFO A and the K3
will transmit on B.
The instant you press the REV button, the *contents* of the VFOs are
swapped and you can listen to the pileup on A (while the REV button is
held, the K3 will not transmit, by the way).
The instant you release the button, the contents are swapped again and
when you transmit it will be on the pileup frequency.
Incidentally, 'the contents' includes the bandwidth. What I like to do
when I hear some DX is to set the bandwidth wide (if it is not already),
press A->B and then SPLIT. Then I reduce the bandwidth to best hear the DX.
At this point I can hold REV for as long as I want to search the pileup
with the bandwidth wide. When I hear the guy the DX is working, I let go
of the button and I go back to hearing the DX with a narrow bandwidth.
The trick is to think of VFO A as the receiver, and the swapping options
as copying the contents of the VFOs, not 'swapping VFOs'.
The REV button is the only button on the K3 which switches between two
states in its up and down positions! All the others use the press/hold
convention that is familiar from the K2.
