1/4/2024 0 Comments Fldigi weather station codesWhen these reports can be associated to a longitude/latitude pair, the report is written in a KML file which can be displayed in Google Earth.ĭuring installation of fldigi, you were prompted to download a couple of data files: These are necessary for decoding many reports. ![]() How do I decode SYNOP weather reports ?įldigi contains a SYNOP decoder, software which translates these cryptic codes into clear weather reports. That way, it keeps the numbers displayed in all circumstances. It is possible to turn this behavior off in the RTTY configuration by turning off the "Unshift on Space", these spaces being the ones between group of words. For example, the following macro selects the DDK9 transmission in the 30m band and puts the signal at the 1500Hz "sweetspot" for the FT-991 :-ĩ56 SMPO60 LPMG 241200 CCA AAXX 24121 08522 32570 49902 10250 20176 30131 40199 52002 82200 222 // 00240 314 // 4030 8304 60005 =īecause RTTY code represent letters and numbers with shift code, it might happen that a transmission error unexpectedly shifts numbers to letters. The mode and frequencies in F1B are, in LSB with 50 Bauds: FrequencyĪ macro key can be setup, if desired, to select the appropriate RTTY parameters. That is, the signal must be inverted and the mark and space put at the right place. FLDIGI Configuration 101 Device dropdown menu- will only display valid Com ports Select computer Com port used for radio interface. If the transceiver is in a USB mode then it is necessary to click on the fldigi Rv (Reverse) button on the bottom menu bar, lower right corner of the Fldigi screen. ![]() SHIP data, are also transmitted are transmitted in RTTY by the Deutscher Wetterdienst (German Meteorological) at regular times.ĭeutscher Wetterdienst (DWD) transmission schedules, frequencies etc may be found at: SYNOP (Also called FM-12) is a numerical code used for reporting weather observations.

CodeĪnd there are 3 Manual character codes which will only be sent on their own: Codeįor more information on the origin and interpretation of Weather Condition Codes, please review the Gempak Parameter guides. The following table outlines the code values which can fill in for A, B or C in the examples above. The following are the steps involved to unravel the values working backwards: The three conditions are represented by A, B, and C in the following formula: ![]() Many automated stations can report up to three “present weather” types which will be returned in a single string (e.g. If a weather condition is present it is returned if there is not a current weather condition the cloud layer with greatest sky coverage is returned. This variable is intended to provide a single string for each observation timestamp summarizing the current weather. The derived weather condition is also included in the derived weather_summary variable. Note that this variable is only reported when there is present weather. ![]() The weather condition code is requested as weather_cond_code, and the weather condition string derived from this code is requested as weather_condition. For legacy reasons we refer to this variable as WNUM or “weather number.” The WNUM is an integer value that can be converted into a weather condition description. Weather stations in the NWS/FAA network (and some RWIS stations) report a weather condition code. DEVELOPER INFORMATION Reading Weather Condition Codes
