There are a few things you have to do to have your weather data beaconed with your position reports.
1. You have to have a weather input port opened on YAAC that is receiving the weather data. Serial_Weather accepts serial port data from Peet Bros brand weather stations; WXNOW.TXT accepts weather from any weather station being handled by Cumulus or similar weather client software. In either case, use the View->Weather Status menu choice to confirm you are actually seeing current data from your local weather sensors in YAAC.
2. In your beacon definition, you have to enable your beacon and check the box to have it Report Weather.
3. Due to a quirk in the APRS Protocol Specification, the course and speed fields of a position report always mean the course and speed of the radio station, not the wind, unless the APRS symbol code is for a weather station (/_ or \_). YAAC is smart enough to recognize when you are using a non-weather-station symbol code that would cause your wind information to be lost, and will send the Position Report (without weather information) immediately followed by a Positionless Weather Report (which doesn't care what your symbol code is). This has the convenience that you could have a mobile weather station (e.g., stormchaser) reporting the course and speed of your chase vehicle in the Position Report, plus the weather data separately. YAAC, unfortunately, does not have support for the vector math necessary to convert air velocity around a moving vehicle into ground-relative wind velocity, so your weather sensors would have to do the math prior to delivering the data to YAAC.
Hope this helps.

Hi All,
Maybe this has been asked but I cant find anything. I am trying to setup my RF port to beacon the weather and position but no matter what I do I cant get the weather to be beaconed with the position.
