[Elecraft] Receiving independent bands

[brian]

Guys,

The solar eclipse is coming and one group is asking for people to record 
8 hours of doppler shifts and amplitudes on as many WWV and CHU freqs as 
possible.

I have a K3 with subrx.  I'm having trouble different frequencies in the 
main and subrx.

Here's what I want to do:
1) Put highest band in the main (14.X MHz)
2) Put lowest band in the sub.  (7.x MHz)
3) Main antenna is shared.

VFO IND is Yes
LNK OFF
VFO's set in split or not (tried both ways).
Put lowest frequency into main RX and set AGC, bandwidth et al.
hit A->B twice to enter all info into the sub rx.

Now here is the glitch.
No matter how I try to enter the higher frequency into A (punch it from 
front panel in or via logging program).  The main RX frequency gets 
copied to B.  Yes VFO linking is off as indicated by no flashing decimal 
point.

The only way I've been able to get what I want is to tune VFO A dial to 
the desired frequency.  A royal pain.

Is there an easier way?
