The spec says, and has always said, that weather MUST be the _
symbol. I can't speak for aprs.fi or libFAP, or any other parser,
but I know that my spec-based parser within APRSISCE/32 only looks
for weather-formatted data in the weather-symboled packets.<br>
<br>
APRSISCE/32 solves the weather vs normal station symbol issue by
supporting weather OBJECTS rather than weather STATIONS. The main
station can be any symbol that you want and the weather information
is sent out as a position-based object with the weather symbol. Two
for the price of one. So, if you've got a station advanced enough
to be formatting weather-type packets, you probably have a station
that can beacon the balloon for tracking and the weather object for
weather. <br>
<br>
But are you really transmitting Weather data if it's "just a
thermometer or radioactivity sensor"? In that case, I'd call it
telemetry and send out the definitions before and after the flight
from a ground-based station and let the telemetry carry the data.
It's certainly not weather that the weather services around the
globe would be interested in if it's coming from 60K feet.<br>

<div>I.e. what if a balloon carries a simple or elaborate weather

<div>icons. It would be nice if they can still use their

<div>packet payload, whether it's weather data or other things.</div>
<div><br>
</div>
<div>Do sites like <a moz-do-not-send="true"
href="http://aprs.fi">aprs.fi</a> only show weather
charts when the /_ symbol is used? I think</div>
<div>it would be interesting to know. I hope they don't and they
look at the packet payload</div>
<div>instead.</div>

How about this for Radiation Telemetry:<br>
<br>
- 3 digits. Either in a WX report or in a Telemetry
channel.<br>
- In a weather report the identifying byte would be "X".<br>
- So X123 would be 12 times 10^3rd nanoseverts<br>
<br>
Using Tapio's idea (below) of 2 digits of precision and
one digit of decade.<br>
