Sorry…  Except some of the Yaesu’s that do not let you set CTCSS on the
APRS channel…

I have a Yaesu VX-8DR and was quite puzzled  when you said that all APRS
radios have this feature. I can’t find any mention of this in the manual.
In fact, there is a setting that “Enables/Disables audio output of the
‘B-Band’ during APRS operation”

What I don’t like about the menu VA is that it then takes another
multi-press menu process to turn it off, even momentarily...

That is why I like the 4 APRS Frequency channel method.  TO change from
normal VA, to SILENT, to open-squelch monitoring, to PRIVATE, and to no VA
is just a twist 1 or 2 clicks with the tune knob to select one of the 4 APRS
channels saved with the different CTCSS/PL methods.

Since I discovered that, I never use the menu method.

Bob also didn't mention that the D710 and D74 have an APRS menu option to
turn on voice alert which is easier than manually setting up CTCSS.

But it is pretty worthless in practice. I have hundreds of thousands of APRS
mobile miles with VA on, I do occasionally hear a station and I call if it
is safe (often it is in a city while towing my fifth wheel and talking isn't
safe), and have never once gotten an answer, nor have I gotten a call...
