Viscous APRS Digipeater is a modification of APRS Digipeater, which puts all packets heard from radio channel into a short term probation delay hold (4-8 seconds,) and checks to see, how many copies of that same packet (per APRS packet duplicate detection algorithm) will be heard during that interval.
If a packet is heard only once, it will then be processed like normal digipeater request. If a packet is heard more than once, it is silently forgotten.
