Stan, I believe this is a limitation of the current firmware. When band
independence of the sub receiver was added back at ver. MCU 3.03 / DSP 2.10,
3-17-2009, it was said that this would be so (for now). The firware release
notes stated that some of these limitations would be lifted in future
releases:
New Feature: Band Independence for the Sub Receiver
* MAIN/SUB RECEIVER BAND INDEPENDENCE. If CONFIG:VFO IND
is set to YES, then VFO A and B can be set to different bands. In this case
BAND UP/BAND DN will only move VFO A, but in BSET mode, they will apply
to VFO B. VFO B can also have a different mode from VFO A. Some RX
parameters can be set differently for the sub receiver when in BSET mode,
including PRE, ATTN, all DSP controls, and NB (noise blanker) settings.
Limitations: For now, NR, notch, and some other controls remain common
to both receivers. Internal text decode (CW, FSK-D, PSK-D) is available
only for the main receiver. Scanning still must be set up using both VFO A
and B on the same band. Memory recall only updates VFO A if VFO B is
on a different band. (Most restrictions will be removed in future
revisions.)
