1) An ambitious undertaking.  Can you catually
get access to ALL digis in the entire area to 
make the switch?

2) If you stay on 144.39 nothing can protect you
from RF QRM.  If you are going to adjust every
digi anyway, then why not move to 144.99 if
available in your area... and then hav ea clear channel.

3) Since we have receommended that all Kenwood
D700's be permanently set to support TEMPn-N
digipeating in the UITRACE parameter, you might
think of setting them up and the fixed digis to that
setting  at the same time for the event.

4) SOunds like your intent is to not support WIDEn-N
during the event.  A lot of locals may have problems
when normal tracking ceases.

5) Better thing to do might be to just make sure 
ALL surroundign digis have good UIDIGI TRAP
aliases in place to trap expected QRM...  
good luck

  Has anyone set up digi's to only respond to trackers for an event like
this? This event covers from N florida into S Georgia (Albany) and I
contemplated using the GA state path since there are not many S Georgia
digi's.  Any other ideas?
