[Elecraft] p3 Tap to QSY in Data A mode

Bob et al,
 
This is not the way I operate in contests, I use the K3's excellent filters!
 
Scenario:-
If 1 very strong station is close to 3 weak stations you will not copy the weak stations due to the strong station shutting the ALC down, so narrow the filters right up and hey, there are the weak stations!
 
So using the P3 to find the signals and leaving the K3 filters narrow works real good for me.
 
Only thing i have to do is use the VFO B knob while VFO A is running where I would like the P3 to tune the K3 with click and shoot to the centre of the pass band when in data A mode.
 
I think this is a feature that’s required for the P3.
 
Anyone else agree?
