[tracker2] Digi Help

[wd0afq]

My Tracker2 has stopped digipeating. The green light does not come on when 
receiveing packets. I do not know if that is important or not. For the past 
week it will only digi 2 or 3 signals in a 24 hour period. I have wracked my 
brain and changed every setting available. Any help will be appreciated.
Thanks,
Dan
