Now, this is a statement I need to check on.  Round these parts I have 
*NEVER* seen "SmartBeaconing" do anything but produce *more* packets than
any sane fixed beacon rate station.  

We have a few stations in the area that are running TinyTrakIIs with smart
beaconing turned on.  When they're operating, I routinely see 3-5 packets 
per minute from them if they're on any kind of windy road --- that is, most
of the ones outside the city.  I think this is due to the corner-pegging 
feature -- great for producing a detailed map of the road up to Sandia
Crest (where a prominent local digi lives), but not very channel-friendly.  
Sometimes I've even seen that level of output from them even when they're on 

Presumably this is due to inappropriate setting of the SmartBeaconing 
parameters, but to date I've never seen a TinyTrak with SmartBeaconing turned
on do anything but spew huge numbers of packets.  Before we had the new N-n
paradigm around these parts, these trackers running RELAY,WIDE were a joy to
have around...  

So what parameters have folks used with SmartBeaconing that has actually 
allowed reasonable packet rates under normal circumstances?
