Last update of ILG data files:  October 1st 2020 (2200 UTC)
Perseus HF Receiver Software with Spectrum Mode in use with ILGRadio Data

The Problem with PERSEUS SDR seems to be the PC Memory because the size and the numbers of files of the databases are quite limited.
PERSEUS SDR is a high tec receiver but the databases to run it perfectly (to display the exact stations in the monitor window) are looking like ILG Database structure of the year of 1985 with PC Memory Space/Floppy of 160 KB and this is more than 30 years ago. It is like to drive an Audi A6 Quattro car with wooden wheels on a German Highway (Autobahn) !!!

ATTENTION:
3 or 4 Userlist files are to big for PERSEUS SDR software !
Use at all only 2 files, e.g. hfcc.txt  and userlist1.txt
 
The small window on right side gives e.g. name of station, location with code and full name in brackets, ITU country code and power in kW. These data can be displayed if special files (2 versions below) of ILGRadio data are stored into your PERSEUS software directory. 


Display for Userlist1 Broadcasting Band 9820 kHz
1. ILG in Text format (Userlist1.txt Structure) with 20698 data sets
   All  stations between 2 - 30 MHz with DISPLAY:
                Time in UTC, Radio Station (5), Days, ITU-Country Code, Language (3), Power in kW / Azimuth in degree
     Usual abbreviations are in use and days are given as 1 = Monday ... 7 = Sunday, "-------" = daily
     Link here to click   (file name userlist1.zip with userlist1.txt)
  
    This files cannot be used with a further "userlis2.txt" in PERSEUS directory and must be use as a single huge size userlist !!!
     Due to memory problems (ILGRadio database is too big) with PERSEUS software to use two userlist files 
 

2. ILGRadio in Text format (Userlist2.txt Structure) with 20698 data sets
   All stations between 2 - 30 MHz including exact Frequencies with Decimal Point
    with DISPLAY:
    Time UTC, Station Name, Days, Power kW, Location, ITU Country Code, Language, Frequency kHz
     Usual abbreviations are in use and days are given as 1 = Monday ... 7 = Sunday, "-------" = daily
     Link here to click   (file name userlist2.zip with userlist2.txt)
 

3. ILG in Text format for PERSEUS SDR (hfcc.txt Structure) with 19342 data sets
    All  broadcasting stations only between 2 - 30 MHz with DISPLAY:
                Time in UTC, Station Name, Location, Longitude, Latitude, Power in kW
     Usual abbreviations are in use and days are given as 7 = Sunday ... 6 = Saturday
 
     Link here to click   (file name hfcc-perseus.zip with hfcc.txt, site.txt and broadcas.txt, admin.txt)

Available files only for HFCC.TXT use:  
site.txt          (sets limited to 999 entries to avaoid display problems)
