The Tracker2 actually has space for the weather firmware at the same time.
I'm still working out some of the interactions, though. You could
conceivably run a mobile weather station, with SmartBeaconing. Not sure
that'd be useful, but I at least need to figure out what options make sense.

A weather / digi configuration would be nice and helpful for public
service events.

Actully, a dead cat would do well also for the WX part. If it is wet, it
is raining, if it smells, it is hot. If it is white, it is snowing, etc.
If you want better temeprature, use a live cat and a ruler. The length of
the cat is directly proportional to temperature. But then you have to feed
it and clean up afterwards, etc...
Sorry, couldn't resist ... Bob

I believe the Byonics can parse the Davis stream, we first used the device
on our weather stations with a KPC3+ and a Peet Bros system because we
wanted to generate 'Kenwood readable' weather. Dumping the Peet Bros
station into the KPC3+ will yield a form of the weather data, but it isn't
compliant with the spec and it isn't readable on the kenwoods. We started
with the WxTracker using it to get the weather data out in a Kenwood
compatible format, but there were some issues with that as well. Weather
went out in one packet and position in another, which isn't so great.
Our solution was a design from the ground up of a product called the
"weatherDog" which parses the Peet serial stream, manipulates and scales the
data, then spits it out into the KPC3+ so that the TNC transmits position
and weather data in the same packet. For the most part it does what we
need. Our engineer recently scaled it down to a 'lite' version that does
most of the same features and is much smaller, less power consumption, etc.
So, if you want quick and easy weather and don't mind that it isn't readable
on the kenwoods, one of the small tracker modules will do the trick.
We planned on making a jumper setting on the WeatherDOG so you could select
Davis or Peet or ?? but it turns out that decoding the Davis stream has been
less than friendly and we've pretty much stuck with one kind of instrument
so we have replacement parts, etc.
Here is what we presently collect from our sites:

By all means!
Positionless WX and weatherless-position are an anathma to the APRS
concept. Please make sure all APRS WX stations transmit the ORIGINAL APRS
WX format (called "complete")which contains both position and Weaher in the
same packet.
In APRS, all information is supposed to be STAND-ALONE and concise, without
any need for apriori info. A single packet should have all you need to
understand what is in that packet.
Positionless WX and weatherless-position for WX stations violates that
fundamental APRS principal. Thanks, Bob, WB4APR.

Byonics does have a version of the WXTrak that sends positioned weather
packets. The chip version that he sent me is v1.2b2 - it works like a
champ. He's also added the Davis support however I only use Peet Bros.
equipment so I can't comment on its functionality.
I'm in the process of switching over several weather stations from the Peet
Bros. hex "packet data" format with the KPC3+ LT buffers to interfacing a
WXTrak with the TNC. In this configuration the TNC will do the digipeating
and the WXTrak will send the positioned APRS standard formatted weather
data that can be read on the Kenwoods. Byon has created another version
that I'm testing now (v1.2b4) that recognizes the PTT-IN like the TinyTrak
does. My concept is the TNC's PTT will connect to the WXTrak's PTT-IN pin
and the WXTrak's PTT-OUT will control the radio's PTT. This way the WXTrak
will not transmit if the TNC is transmitting (digipeating). Right now on
the bench it works great - I haven't put it on the air at an actual digi
site yet but I don't anticipate any issues.
For what its worth...when I setup the Peet hex "packet data" with the TNC I
set the position LT & weather LT to transmit at the same time. This way
they go out one after another "sort of" creating a positioned weather
packet.
Regards,
Richard

Well dagnabit. I forgot, if its not for DOS or a D700....
Couldn't resist either.
