[aprssig] Bob, Address the WIDE7-6 Possibility

Hi Curt,

That is what I was really trying to understand about changing home 
RELAYs to WIDEn-N.. These home RELAYs had a very important roll all 
along. But, if they become WIDENs, then the unless your ideas can be 
implemented, it could be bedlam all over again!

Until recently, I had never heard that the home RELAYs were meant to 
help a mobile make a WIDE digi through QRM.. I understood they were 
there because of the mobile's weaker signal, and fluttering while 
moving, not QRM.

Now, how can a home WIDEN prevent digipeating, unless it doesn't hear 
someone else do the job for the mobile?

This would be cool!

Robbie
