Correct.  To scan from MEMORY one must define what you're scanning for.

If scanning in Analog with the "auto dv" function turned on, if the rig 
"hears" DV (digital) traffic, it'll switch.

I haven't played with it too much, been too busy operating!  (GRIN)

Very much agreed.  Even as an analog rig, it's pretty darn good.

Complaints about the IC-91AD would include:

- Runs hot on high power.  Hot enough it's uncomfortable.

- If powered externally with too high a voltage, the rig drops down to 
about 300 mW of output power, even though you're in the range specified 
by Icom.  (Try it sometime on the workbench with a dummy load hooked up. 
  Very interesting.)

- When powering from external power, the voltage regulation circuits in 
the rig add to the already hot operation... the rig gets rediculously 
hot.  (Buy oven mitts or an external speaker mic.)

- Audio circuits aren't loud enough.  Again external speaker or speaker 
mic helps here.

- "Auto" squelch sucks (but most do).  Set a real squelch level setting 
and forget about it.

- Default settings for DV mode can cause problems.  Turn off "Auto 
callsign copy" of anything except RPT2 field if your Gateway has D-Plus 
installed.

- Memory A and B banks are tied to specific receivers, almost like it's 
two separate rigs.  I don't like this, but it's manageable.

- Programming anything this complex through the keypad is a giant pain. 
  Get the programming software and cable.  (The plus is, the programming 
cable doubles as the data/serial cable on the HT's -- not on the mobile 
rigs.)

- The thing eats batteries alive.  On the to-do list to get more or the 
aftermarket bigger one.

That's my "list"...
