The ultimate Source for the HF Planning and HF Frequency Management
This is the complete database of all final schedules (tentative schedules before season starts) with data of the whole season. Full language details and verified technical data are also included, e.g. antenna details with the precise design frequencies based on special ILG research and internal documents.
Starting April when summer season starts (November for Winter season) regular band scans results are included and the monitoring date is given in the MDATE data field, e.g. MDATE 030517 = monitored on 3.May 2017. All monitoring work is made by PERSEUS SDR receivers in the ILG office in Germany and by remote receivers in Europe and Overseas.
Broadcasts which are not on air but required at HFCC (so called wooden) given with "minus" power. Possible alternative (stand-by) transmissions are included as "alternatives" in the database. In the WPLOT software those "wooden" entries with minus power are displayed with a different colour on the world map.
Additional monitored Sign/on and Sign/off times based on current observations are also included. Additional un-listed transmission times of Warm-Up and Warm-End with silent carrier, interval signals or programme parts are also listed in the ILG database.
In the data field NOTES the ILG gives unique information for non-active transmissions: Alternative, Double Entry, Fiction (a higher level than not used), Inactive, Special Events.
