<div><SPAN style="font-size:10pt;">1) The first WIDE1-1 gets digi'd by either fill-in or normal digi's. No digi ignores it.</SPAN></div>
<div><SPAN style="font-size:10pt;">2) If you specify a total of two or three hops, you will get two or three hops. There is nothing magic about hitting an IGate to stop digipeating. It would not matter much anyway. By the time your packet reaches an IGate it has probably been heard by several other digi's too, so your radio footprint will continue to expand until the last "N" is used up.</SPAN></div>

<div><SPAN style="font-size:10pt;">I am not on top of the meanings of the various symbols. Perhaps someone else can help with that.<br />--</SPAN></div>
