Ah... I get it now. You want to see ALL the raw data including the dupes. It
sounds like that would be a fundamental change if the APRS-IS didn't throw
out the dupes.

Re dupes... I actually think it would be a good thing if the  APRS-IS went
back more than 30 seconds looking for dupes. I don't know if the servers
would need more horsepower or not, but if they did dupe checks for a minute
or even better, two minutes, we would see less zig-zagging of stations
caused by delayed packets. I was watching a mobile station this morning and
many of the dupes were just over 60 seconds in age, but some were up to two
minutes.
