Is this normal? Possible bug in QRQ mode

When I enable QRQ mode, the SHIFT control is locked at the center of the passband (*0.60).

o If I disable QRQ through the Config menu, functionality of the SHIFT control is restored.

o If I disable QRQ mode by turning on an incompatible VFO mode -- RIT, for example -- functionality of the SHIFT control is restored.

o If I turn on APF while in QRQ mode, SHIFT works. If I turn off APF, SHIFT reverts to *0.60 and is locked until I disable QRQ.

Is this normal behavior for QRQ mode? I’ve looked through the release notes, and I can’t find anywhere that it says SHIFT is locked to the center of the passband when QRQ mode is engaged.

Bill,

No bug - that is the way it is.
If you check the firmware release notes for MCU 4.03 you will find it
stated that you cannot use shift while QRQ is active. Yes, it does not
explicitly say that the shift is locked to the passband center.

In firmware MCU 4.22 release notes, you will find APF. It says when APF
is turned on, the regular SHIFT is frozen, and the SHIFT control is then
used to control the APF (but not the IF SHIFT).

73,

As Don has said, this is normal.

The reason why some of this is done is because the items which are
disabled in plus mode require "settling time" and are users of CPU
budget during RX/TX/RX transitions. Blinding QSK doesn't have any
time to mess around. There is an as yet only outlined intention on
Wayne's part to allow some very limited aspect of the disabled
functions and an automatic passage between normal and plus mode to
make things more seamless.

73, Guy.
