I think it works because it does work.  That's how
I've been using the radio long before this idea of
inserting my frequency into the packet (which is a
feature I don't need).  If someone calls me on
Repeater X and my radio stops there, I'll start
talking to them.  If at the same time someone calls on
Repeater Y, I won't hear them, this is true.  BUT, the
person who called me on Repeater Y is typically also
scanning just like I am, therefore after they give up
on Repeater Y and resume scanning, they'll hear me on
Repeater X.

I know it seems strange but it works just fine.  My
whole issue was not about whether I could be found or
not found.  My issue was the fact that the radio was
aborting a memory scan every time it beaconed in
automatic mode.  Plus, if I'm scanning, then having
the radio broadcasting a packet with a frequency is
pointless because I'm moving to different frequencies
each time and thus be very confusing as someone else
pointed out on the list.

It's an interesting feature and I can see some use for
it in some situations or operating methods.  But, it
isn't suited for my typical operating method for the
reasons that I scan and that most people here don't
use APRS so it's just wasted data.  I just objected to
a radio behaving like this was the only way to operate
and not giving me a choice in the matter.
