But I'm not jumping in frequency, I'm letting the
radio do its memory scan through a set of repeaters
that I do listen to, all of which are within reach.  I
get found when someone calls me on a repeater not when
someone looks at my packet.  But to have the radio
suddenly decide that I can't scan memories while using
APRS because it wants to send (or think it wants to) a
frequency all the time is NOT useful.  Besides, you've
harped on Voice Alert all this time, if people wanted
to get to me, they could use that.  I don't keep my
second band locked on a single frequency when I'm
driving, I'm listening to multiple repeaters.

>From what is being described, it would appear that the
radio halts the scan for the express purpose of
acquiring the frequency to put in that beacon.  The
proper method of operation would be to acquire and
beacon a frequency if and only if the radio is NOT
scanning and then ONLY if the beacon text is
programmed to acquire a frequency.  If not, then it
should honor my wishes and continue scanning on the
band while it beacons normal APRS packets.
