[aprssig] Questions about being both an iGate and digipeater.

[Randy Love]

Actually the doubling *is* encouraged.
It's this "packetcide" that keeps the packets from bouncing around taking up
more slots than they should. The idea is that your digi and another digi
within earshot of each other will transmit at the same time to keep from
taking up 3 time slots for a single outbound packet.

Read here in the KPC3+ settings why uidwait ( or just dwait ) should be OFF
or 0.
