current Structure of dBASE Format of ILG Database for dBASE and Excel Import
The current Structure of ILG Database
All files are including 1535 "Separator Lines" and the data field of GRAPHIC (Graphical Diagram) looks like this:
00##########06##########12##########18##### 6100
Other fields are filled with "#####". This should look like a black line to separate optically the 5 kHz steps
within the broadcasting bands and plus/minus 100 khz. ALso in use for 1 MHz steps.
If frequency allocations are changing also such lines are included giving details in the NOTES data field.
ILG data entries and information are based on old and current monitoring experiences made over the last 40 years...
Exclusive ILG data fields are NA,CA,SA,EU,AF,ME,AS,AU,PA since 1989 and the usage is exclusively only allowed to use by ILG Database and not by any other software
Effective from August 25th 2019
