I am glad someone has made reference to the national web page on the TT 
settings allready.

I was really tempted to try and contact Stewart again . In the last couple 
of days his beacons have been excessive at times from -15 back out on 2m .. 
I imagine this is his HF setup being -15 .. 3 separate beacons in less than 
a minute all nicely spready apart. He is a bit the same on 2m at times also. 
Perhaps its just while he was testing. Ive recently emailed Paul about some 
of his frames as well. We are all learning so I just encourage all to have a 
real look at what your transmiting on air and how often. Using the internet 
facilities like APRS.fi and Findu is not the way to check it. Paul for 
example has been transmitting a beacon quite frequently that is non APRS 
compliant and gets ignored by the internet servers and all the APRS client 
software like Ui-view. So it truly is just junk value (pollution).
I watch whats happening on air using programes like TSTHost for Windows and 
Win-TNC . Looking at frames as they are sent and digied. Its really amazing 
whats going to air. Frankly its time we had a good look at whats comming out 
of the Igates as well as what our mobiles are transmitting. Simply put 
things are going to be changing.

I use a D700 (no smart beaconing) when mobile with about 20w into a half 
decent antenna in the metro area. I use a beacon rate of 2 mins in the metro 
area as a rule. Ive been doing this for over 2 years now. The value of smart 
beaconing is limited apart from it being a great way to dominate the 
frequency. One area smart beaconing is good is changing the beacon rate when 
stationary. Corner pegging should be outlawed ! If your hoping to track your 
vehicals down to the nearest 20m in the last 10 seconds on precision maps 
then APRS and 2m/HF  is not the way to do it.

Strong opionions like that aside back to your original question Darryl 
regards the 16km/Hr .. I cant find any reference to 16Km/Hr anywhere on that 
web page. Where are you comming from on this? I suspect herin may lie some 
of the misunderstanding . Did you convert one of the values on there to 
metric ?

I cant help but find the configs for these Tiny trackers are really 
unhelpful when they start using units like Knots. Miles an hour is bad 
enough when most of the world is metric but knots means little to most of
