[aprssig] Digi Question

I'd recommend setting up a TNC connected to the radio and antenna that 
you propose using for the digipeater and then listening, recording, and 
observing the local RF network.  If you copy packets directly and also 
the digipeat from the existing digipeater, then you really won't be 
adding any benefit to the network.  If you copy packets directly that 
the existing digipeater doesn't seem to copy, then map out where they 
are to determine if your coverage of that area would be beneficial or not.

APRSISCE/32 has a path display capability that can make such local RF 
network analysis rather fun to do.
