I think, this is perfect if digi operators are perfect. One of my neighbor 
W1 digi works with PL100, so every repeated packet comes out with the tone. 
Even when I don't use PL100, I can hear 100Hz burst when MY POS blinks on 
the display. Moreover, some mobile station driving around activated D700 as 
a WIDE1-1, WIDE2-1, WIDE2-2 digi and works with PL100. So, most of local 
packets suggest their original operators are VA active and in simplex range 
but they are not.
