No, you failed to use any logic at all here (gee, I'm surprised). Many
of us own multiple Kenwoods (I own a D7 and a D700). Just for the
record on the database scan I just ran, there are 4979 unique callsigns
(eliminated duplicate SSIDs) running Kenwood radios in APRS mode as
5,705 stations out of the 17,749 unique callsigns operating 25,054
stations. Hope this clarifies the numbers for you. This means (to use
your shouting text) that LESS THAN 28% OF ALL APRS USERS (ignoring ALL
OF THE USERS who do NOT transmit a position such as web users and
clients in monitor-only mode) use a KENWOOD.

Gee, why don't you use the same logic for the Kenwoods? Oh yes, you
have to save face with them because you are afraid to ask them to fix

It is only deprecated because YOU say so to accommodate a Japanese radio
manufacturer who didn't program the radio to full compliance. This is

It would be nicer to get Kenwood to update their firmware, but this
doesn't server your purposes... Easier to tell multiple software
authors to modify their software than to go to a single manufacturer and
tell them where their radios are not in spec, right?
