<p>Hi Bob,</p>
<p>Hi everybody,</p>
<p>would it be possible to add new symbols, relative to APRS of
Things, mcu-driven devices for beaconing, telemetry, remote
controlers, reporters... objects?<br>
The aprs equivalent of IoT but specifically dedicated to mcu
ham devices.</p>
<p>I<span style="font-size: 12pt;">’m thinking about icons based
on</span><span style="font-size: 12pt;"> coloured only
symbols, similar to the '1 to 9' ones located in the primary
table, but using the alternate symbols table, thus allowing
the use of alphabetic A-Z overlay over the 9 different
coloured primary icons and greatly increasing possibilities
and richness of Ham of Things icons set.</span></p>

<p>APRS symbols are not transmitted over-the-air as little
bit-maps. Only two-character control codes are sent, that cause
symbols already stored on the recipients' systems to be
displayed. As a result, you can't make other stations see a new
symbol just by transmitting a new code from your station. <br>
</p>
<p>Adding any new symbol would require updating the current symbol
set stored in thousands of hardware devices (like Kenwood and
Yaesu APRS radios) and copies of APRS software on thousands of
computers, tablets, smart phones and web sites. In many cases,
the embedded symbol sets are not accessible to change at all.</p>
<p>As a result, introducing new symbols is an uphill battle that has
been proposed many times over the last two decades or so. (With
little success!)</p>
