I meant it wouldn't be a valid comparison because based on Fred's
comments, coverage wasn't very good in his area. While his test would be
with his HT and his in-vehicle based digi in more or less the same
place, they would both be beaconing away in an area where he says even
his 40W tracker doesn't always make it to a WIDEn-N digi unless it goes
through his home fill-in digi.

I understand that and fully agree!

In Fred's case, it might be something like "if a tree falls in the
forest and no digi or IGate heard it, did it make any noise? hi!

streets last turned onto.

OK, I'll concede that it's a useful test, but it would be more useful if
his test was while driving where there was near 100% reliability to his
fill-in digi AND near 100% reliability from there to a WIDEn-N digi that
could be heard by an IGate... or by another digi that could be heard by
an IGate. While there will never be 100% reliability, there is certainly
better coverage in some areas than others.

If Fred always operates in an area where coverage is very poor, he
might want to consider using more aggressive settings even with
SmartBeaconing. I certainly wouldn't recommend any such thing if he
was operating where there was more APRS infrastructure and more
APRS users sharing the precious bandwidth.
