Bill drops the complete trailing WIDE2/WIDE2* at the last hop. So there 
will be one complete VIA call less; this will save 7 bytes of data. I 
think Bill's proposal makes sense since one can easily count te number of 
calls already replaced.

So with your previous remark I now have 2 options:

1) End the packet with a trailing WIDE2* like:

     WB0ABC>APRS,KB0ABC*,N0ABC*,WIDE2*
or

2) End the packet without a trailing WIDE2* like:

     WB0ABC>APRS,KB0ABC*,N0ABC*

In both cases any calls following the original WIDE2-N will be kept too if 
there are any, like NOGATE, RFONLY or maybe distribution directives like 
WORLD, LOCAL and IGATE, but also an additional WIDE2-2.

This detailed discussion may look a bit like nit-picking, but I want my 
template to be okay since it will most likely be copied a lot without 
adjusting a lot. So if my template is wrong, it is likey any error will op 
up everywere...

Kind regards,

Henk.
