      If you can use VB to read binary files, I can supply the file format.

      Message 2 of 7 , Nov 2, 2008

        Here is the format of the history.dat file that is output by WUHU. This
        matches the file format output by the Heavyweather Pro application. The
        HW Pro application supports WS-36XX stations. We use the HW Pro
        application to graph the history files output by WUHU.

        This format was chosen because it contains more fields than the old HW
        Beta 2.0 format.

        New records are added to the end of the file, there is no header or
        trailing record.

        The [X] field denotes the number of bytes in the field.

        00 Double [8] Timestamp days from 12/30/1899 00:00:00
        (GMT)
        08 Float [4] Abs Pressure hectopascals (millibars)
        12 Float [4] Relative Pressure hectopascals (millibars)
        16 Float [4] Wind Speed meters/second
        20 ULong [4] Wind Direction see below
        24 Float [4] Wind Gust meters/second
        28 Float [4] Total Rainfall millimeters
        32 Float [4] New Rainfall millimeters
        36 Float [4] Indoor Temp celsius
        40 Float [4] Outdoor Temp celsius
        44 Float [4] Indoor Humidity %
        48 Float [4] Outdoor Humidity %
        52 ULong [4] unknown - (Value is always 0)

        Wind Direction

        Wind direction is encoded as an integer between 0 and 15. To get the
        wind direction in degrees, multiply the value by 22.5. To get compass
        directions (moving clockwise) 0 is North, 1 is North-Northeast, 2 is
        Northeast, etc...

        0 N
        1 NNE
        2 NE
        3 ENE
        4 E
        5 ESE
        6 SE
        7 SSE
        8 S
        9 SSW
        10 SW
        11 WSW
        12 W
        13 WNW
        14 NW
        15 NNW

        C data structure that mimics this format:

        struct WeatherRecord3600 {
        double fTimeStamp;
        float fOutdoorAbsolutePressure;
        float fOutdoorRelativePressure;
        float fOutdoorWindSpeed;
        unsigned long ulOutdoorWindDirection;
        float fOutdoorWindGust;
        float fOutdoorTotalRainfall;
        float fOutdoorNewRainfall;
        float fIndoorTemperature;
        float fOutdoorTemperature;
        float fIndoorHumidity;
        float fOutdoorHumidity;
        unsigned long ulUnknown;
        };

        The fTimeStamp is an odd field. It represents the days since a epoch
        time (12/30/1899 00:00:00) in UTC local time. The fractional part is
        used to obtain hours, minutes, and seconds. There are a few functions
        that are needed to convert back and forth between that timestamp format
        and the normal local time format, they are given below.

        To convert from a normal time_t to this format you would use:

        time_t t;
        WeatherRecord3600 wr3600;

        wr3600.fTimeStamp=Convert_time_t_To_DateTime2(ConvertLocalToUTCLocal(t))\
        ;

        To convert from this odd timestamp to a time_t:

        t=ConvertUTCLocalToLocal(Convert_DateTime2_To_time_t(wr3600.fTimeStamp))\
        ;

        -----------------------

        double Convert_time_t_To_DateTime2(time_t vtime_t)

        {
        double fresult;
        // 25569 days from Saturday, December 30, 1899 to Sunday, January 1,
        1970 (where time_t seconds counts from)
        double fDeltaDays = 25569 + (vtime_t / (60 * 60 * 24));
        double fFractionDays = (vtime_t % (60 * 60 * 24)) / (double)(60 * 60 *
        24);
        fresult = fDeltaDays+fFractionDays;
        return (fresult);
        }

        //----

        time_t Convert_DateTime2_To_time_t(double fTime)

        {
        return (time_t)((fTime - 25569.0) * 86400.0);
        }

        //----

        time_t ConvertUTCLocalToLocal(time_t t)

        {
        // Aquire a local time and a gmt time.
        struct tm tm_localtime;
        memcpy(&tm_localtime,localtime(&t),sizeof(tm_localtime));

        // Aquire UTC time.
        struct tm tm_gmtime;
        memcpy(&tm_gmtime,gmtime(&t),sizeof(tm_gmtime));

        // Convert them back to time_t types.
        time_t t1=mktime(&tm_localtime);
        time_t t2=mktime(&tm_gmtime);

        // Subtract from local time the difference between local time and gmt
        time.
        t1 += (t2-t1);

        // If daylight saving time in effect, subtract an hour.
        if (tm_localtime.tm_isdst)
        t1 -= 60*60;

        return(t1);
        }

        //----

        time_t ConvertLocalToUTCLocal(time_t t)

        {
        // Aquire a local time and a gmt time.
        struct tm tm_localtime;
        memcpy(&tm_localtime,localtime(&t),sizeof(tm_localtime));

        // Aquire UTC time.
        struct tm tm_gmtime;
        memcpy(&tm_gmtime,gmtime(&t),sizeof(tm_gmtime));

        // Convert them back to time_t types.
        time_t t1=mktime(&tm_localtime);
        time_t t2=mktime(&tm_gmtime);

        // Subtract from local time the difference between local time and gmt
        time.
        t1 -= (t2-t1);

        // If daylight saving time in effect, add an hour.
        if (tm_localtime.tm_isdst)
        t1 += 60*60;

        return(t1);
        }

        ---------------------------------

        For completeness sake, here is the HW Beta 2.0 format. As you can see
        the data set is not complete. There is for example no relative pressure.
        That would have to be determined by either reading the relative pressure
        from the console or by prompting the user for an offset from the abolute
        pressure.

        Source: http://www.niftythings.org/HeavyWeather%20History%20Format.txt

        HeavyWeather V2.0 beta La Crosse WS-2310 and WS-2315 weather stations

        Each row of data is stored in 36 byte chunks starting from the beginning
        of the file (no header).

        Row
        Offset Type Name Unit
        ------ --------- ---------------- -----
        00 ULong [4] unknown - (Value is always 1)
        04 ULong [4] Timestamp seconds from 1/1/1900 00:00:00

        08 Float [4] Abs Pressure hectopascals (millibars)
        12 Float [4] Wind Speed meters/second

        28 Float [4] Outdoor Temp Celsius
        32 UWord [2] Indoor Humidity %
        34 UWord [2] Outdoor Humidity %

        At the end of the file is an additional 28 bytes providing information
        about the dataset as a whole.

            Hi Larry
            Been real buisy latly. In september I upgraded my ham ticket to Tech. Early october made $400 off EBay and bought a like new Kenwood TS-140S off EBay. Now I managed to get and fix this LaCross WS-2310 off EBay and get it fixed. Hoping this next spring to make a Skywarn spotter class and get my spotter ID finaly. I have a Kenwood TH-75A I picked up in a local goodwill last march for $5. It was a heck of a find. So im compleatly outfitted for both HF,VHF & UHF now. As well as having proper weather observation equipment. Thinking of getting one of those hand held anometers with temp ect. next for feild use. I decided to get involved with Skywarn almost 6 years ago and just now finaly getting all the necisary licencing and equipment gatherd together. So it feels real nice getting this second to final peice of the puzzle put into place. Still have to get that spotter ID. But its the last peice I need. EBay has been a real blessing to me. Finaly able to take the gatherd stuff I do find and sell it for the money for the stuff I realy need.
