Question for those users/designers of the K3 sub receiver and split
capabilities:
Refering to manual version C1.November 18, 2007, page 35:
The discussion about using split mode with the "sub" is confusing.
Let me explain what I think the manual is saying and if it's incorrect let me
know:
In split I receive with the main receiver on VFO A, and transmit on VFO B.
When the sub is on, I can receive on VFO_sub. Does the sub have a VFO label
during split? What is the label of this "VFO_sub" ?
So in split, to review: I am listening on VFO_A, Transmitting on VFO_B and
listening also on VFO_sub ?
Is there a capability in the K3 to make the frequency for VFO_sub follow and be
the same as whatever frequency is set on VFO_B and vice versa (VFO_B tracks and
is set to whatever VFO_sub is set to). By follow, I define that as when I
set VFO_sub, the VFO_B is set to be the same. And by vice versa, I define
that as when I set VFO_B, the VFO_sub is set to be the same.
The problem I see (or made up) is that I see the benefit of having VFO_sub
to listen to the pile up in split, but without a coupling of VFO_sub and VFO_B
then it would require setting both the Tx VFO_B and VFO_sub.
The use case scenario:
Go split
Turn on sub
Set VFO_A to a frequency of the DX transmitter
Set VFO_sub to a frequency of VFO_A (for reference)
Listening to the DX, you learn the approximate frequency to Transmit on.
Set VFO_B to that frequency
Set VFO_sub to VFO_B frequency (manually?)
Now as I listen to the DX on VFO_A for adjustments to his listening frequency,
I adjust VFO_sub .. When I find the frequency DX is listening on, I'm ready to
transmit but then I'll have to re-adjust VFO_B to match the frequency I want to
transmit on based on my scan of VFO_sub..
What am I missing here? Are VFO_B and VFO_sub coupled in any way?
If they're not coupled in firmware for their frequency assignment, then I
can see (or made up) a problem of having to track the best frequency to
set VFO_B and setting VFO_sub. I'll be setting one to listen where to
make my transmission and it would be great if the VFO_B was ready. The
way I read this manual, it sounds like I have the benefit of listening to
VFO_B prior to transmitting via listening to VFO_sub, however the
macination of setting VFO_sub to find the right frequency is half the
work: I also have to re-set VFO_B before I transmit.
