VWSaprs version 2 has been released
Meteorologica:
Just to let everyone know that we have released a new version of VWSaprs. You can download it from http://www.meteorologica.co.uk/APRS/VWSaprs.zip
Most importantly is the fact that this version will run with any edition of VWS, not just the Internet edition. This should allow even more people to be able to send data to the CWOP network.
This new version is Vista and Windows 7 friendly and can save configuration data without needing to be run as an administrator.
It also adds a number of new functions that weren't available in previous versions:
1) Pressure sent by Davis weather station owners is now QNH rather than the Davis calculated QFF, and is therefore more accurate for users at altitude reporting to CWOP.
2) You can now remove specific sensor information from the data stream so broken sensors now don't send bad data.
3) Luminosity can be added to the data stream.
4) Its now possible to send data every 5 minutes
5) The number of weather station types has been increased
6) The weather station type is now sent in clearer English rather than the archaic and unreadable coded method previously used.

"1) Pressure sent by Davis weather station owners is now QNH rather than the Davis calculated QFF, and is therefore more accurate for users at altitude reporting to CWOP."
Would you please define "QNH" and "QFF".
Thank You.

Meteorologica:
QFF is the method used by Davis to calculate sea level pressure. It involves temperature and humidity to calculate the weightof air. MADIS prefer to use a simple adjustment using a standard air weight for their sea level data, this is QNH, also known as Altimeter Pressure. These two sea level pressure values becomes quite different for users as altitude increases. Now, for Davis users, we are finally sending the required pressure value to CWOP. Other stations types don't calculate QFF so this doesn't matter to them.
See http://en.wikipedia.org/wiki/Qff and http://en.wikipedia.org/wiki/QNH
Andy Thompson:
Why isn't there that option to automatically start this program at Windows start up?

Hi Tim
There seems to be a bug because my Temp and Dewpoint have gone wacko Temp is reading 327 instead of 64 degrees F. :shock:

P.S. everything disappeared but you still get the box with the tabs but there is nothing else showing and to get it back you have to stop then restart VWSaprs......
