Question on P3 operation

[John AE5X]

From the P3 manual"
"VFO A has a green cursor and VFO B has a magenta cursor unless split mode is activated at the K3. In split mode, the VFO B cursor changes to red as a reminder that you will transmit on that frequency."

Just to verify, is this true even without a sub-rx? In other words, with SPLIT enabled (and no sub-rx) can I still move the cursor on the P3 for VFO-B with the VFO-B knob on the K3?

Hi John,

I can speak for the small U shaped cursors. My explanation might be incorrect for the tall cursors.

Yes, VFO-A is green and VFO-B is magenta. The magenta cursor doesn't change to red. A third cursor, red, appears when you are transmitting on an offset frequency. You will see it when you turn on split or when you turn on XIT or RIT. Normally the red and magenta overlap so you may not see magenta. You will see red and magenta sort of overlapping if you fiddle with your bandwidth.

Yes, turning VFO-B will move the magenta and red cursors. If they move off of the screen you will see a magenta and a red arrow (if your transmit frequency is offset) or just a magenta arrow.

All of this applies whether you have a SUB RX or not.

John,

The VFO B has no direct relationship to the subRX.  The K3 simply has 2
VFOs - try to think of it that way rather than anything about the subRX.
While it is a fact that with the subRX installed, VFO B is normally used
for tuning the subRX, but that can be altered.
Without the subRX installed, and with SPLIT activated, VFO B will
control the transmit frequency.
Observe the 'arrow' on the right of the display which indicates which
VFO will be used for transmit.  The VFO B cursor on the P3 is another
reminder of the TX VFO.
