Paul & all,<br>
<br>
I did some more massaging on the Symbol Usage numbers that I extracted
from my North American APRS-IS coverage database. This represents
weeks of reported stations where Uses is a station count and Packets is
total packets over some number of weeks, not just 6 days. Feel free to
slice/dice this data in any fashion you see fit.<br>

PS. Note that the attachment is an Excel 2002 multi-spreadsheet file.
If you can't handle that, here's the top station usages down to 100
(out of 23,297 total).<br>

PPS. Don't ask me about the 0/0. I don't know where it came from, but
I suspect my symbol parser has a problem with some sort of packet
coming over APRS-IS. I'll have to look into that now that I see it!
Don't know how I could have missed it on 209,000 packets (out of
27,700,000). Yeah, right! :)<br>

<pre wrap="">Lynn,
With your database of 6 days, would you be able to generate a
histogram of the symbol usage on APRS? I'm trying to gather usage data
to convince GPS manufactures to add some additional symbols for APRS
and figures I should start with the most used ones.
