[aprssig] TEMPn-N and callsign digipeating

[Robert Bruninga]

Maybe it is symantics, but If I may suggest, the first thing 
to do is to upgrade that main Knoxville digi to New-N to 
support WIDEn-N.   It was disappointing to disappear for 
over 200 miles and almost 3 hours while driving through 
central tenessee last year.

But that was a year ago, I thought that they had recently
upgraded that digi?

Presumably if it is just that one station, he couild do
just a little bit to his home antenna to pull it in?

If everywhere else is covered, you could put a low
power WIDEn-N digi near him.  Say at the 1 watt
level or less....  that would let him see everything,
but not add a lot of QRM to everyone else?
