And missunderstanding is rampant.  As I said yesterday, there is
nothing wrong with a 2 hop WIDEn-N path in a balloon in a proper
APRS New-N paradigm network.

There is remarkably little difference between a 1-hop and a
2-hop path at altitude using balloons:

Every digi that hears it will digipeat it once and only once.

The load in the area of every digi within hundreds of miles is
no different than a 1 minute mobile driving though.

The ERRORS yesterday in violation of all recommendations were
1) Use of an arrogant 30 second period
2) Use of WIDE1-1 as the first hop 

The benefit to the balloonist of 2 hops is important and causes
little added QRM and should be tolerated.  30 second rates and
using WIDE1-1 should be corrected.
