Perhaps I've got the wrong end of the stick, and it's only for curiosity's
sake I mention this, but I did not think it was possible to independently
set crystal filter and dsp bandwidth. As I alter the width control, filters
kick in at the appropriate points, and if I use the XFIL button I just jump
between the crystal filter widths and the dsp comes along for the ride.
Have I missed something? Or maybe misunderstood what is being said...
The DSP width can be adjusted within the range of the currently selected
filter, though. The issue is that the NORM function reverts back to the
default filter for the current mode, rather than reverting the DSP to
the normalised width for the currently selected filter. I find this
unintuitive too.

The memories are a great feature, but I still think it could be augmented.
1) The last thing I expect to happen when normalising (1/2 sec press basic
function of the Norm button) is for the radio to switch filters, there is an
XFIL button for that if I need it. I think this has a negative effect on the
user friendliness of the transceiver.
In firmware:
instead of,
Change to default roofing filter for that mode and normalise DSP around it.
replace with,
Determine current roofing filter in use and normalise DSP around it.
2) When using the norm memories, I've noticed that if you memorise a 1KHz
roofing filter and 700Hz DSP, then recall that memory, you get the 'wings'
on the filter display associated with the passband being normalised when
clearly it is not.
