    future new digital modes can be automatically identified as such during QSO import.


Version 8.5h release notes

Changes in this version are all related to the Logbook of the World (LoTW):

  • The ARRL official users list (first published on July 29th, 2017) is now used;
  • The last upload date for each user is now displayed in the LoTW users check;
  • Users who did not upload any log for some time (configurable between 1 and 120 months) can now be ignored.

After installing this version, please update the LoTW users list with: Tools --> "Update LoTW DB (Internet)"

If you wish to ignore LoTW users who did not upload any log for some time, go to:
Options --> LoTW; check "Ignore users with last upload older then:" and select the time you want.

A new version of the Telnet directory is also available; use: Tools --> "Update Telnet DB (Internet)"


Version 8.5g release notes

Changes in this version are:

  • DXCC: full support of the 60 m band (alarms, stats).


Version 8.5f release notes

Changes in this version are:

  • CAT: added support for Elecraft;
  • CAT: added FSK setting (no frequency shift) also for digital modes other then RTTY;
  • DXCC and IOTA personal databases can be reset to an empty state;
  • import LoTW report (ARRL) : changed the site address from to

Further, the IOTA reference AN-014 is now handled as a deleted one (more details here).

Version 8.5f is available from the download page as a full version (for new installations or upgrades from versions older then 8.5) or upgrade (from versions 8.5-8.5e only). Both versions are executable files including an install utility which allows an easy installation in less then one minute.


Version 8.5e release notes

The main purpose of this version is to fix 2 annoying bugs from version 8.5d:

  • the IOTA database update (from local file or from the Internet) often generated a wrong error message about an incorrect file size;
  • the program did not load all databases while starting if the WWV database was empty.

Further, the IOTA reference EU-155 is now handled as a deleted one, as all existing credits were removed for this one and no new credits may be gained (more details here).


Version 8.5d release notes

Changes in this version are:

  • CAT: should now work with all Icom models;
  • CAT: 2 transceivers can now be controlled also if they share common bands;
  • CAT: to control only TXVR1, use Ctrl+right click; for TXVR2, use Alt+right click (a right click alone still controls both transceivers); 
  • added identification of calls in the form 9M*/2, 9M*/6, 9M*/8, ZL*/7, ZL*/8, ZL*/9;
  • the latest SFI value is now displayed in the status bar;
  • some spots on 29 MHz were identified as 2 m spots: fixed;
  • improved the detection of broken links.


Version 8.5c release notes

This version's main purpose is to correct problems with the serial port and telnet driver embedded in version 8.5b.

Other changes since version 8.5b are:

  • correct identification of calls in the form EA*/6, EA*/8, EA*/9, OH*/0, SV*/5, SV*/9, R+U*/n;
  • improved the prefix identification procedure in the Country window which should no more display erroneous “Prefix not found” messages.


Version 8.5b release notes

This version's main purpose is to automate several DXCC prefix changes in the personal DXCC databases. More details on this topic can be found here.

Other changes since version 8.5a are:

  • ADIF import may fail if incorrect QSO records were found (with critical fields missing or empty): fixed;
  • in Options - Extras - "Link callsigns to IOTA references", some valid IOTA references were rejected: fixed;
  • the Icom CI-V address range was extended up to DF in Options - CAT.


Version 8.5a release notes

What's new in this version?

This is a mainly a bug fix version which should fix the following problems:

  • DXCC import fails if the ADIF file includes binary data
  • CAT frequency setting in RTTY inadequate when using FSK keying (check Options - CAT - Digital modes for the new choices)
  • Option "Same priority for LoTW and paper QSL's" not working properly
  • Error “Your IOTA.DAT seems to be corrupted, can´t start RXCLUS” after updating the IOTA database over the Internet


Version 8.5 release notes

What was new in this version?

Here is a list of the most important changes in this version :

    • Full compatibility with Windows Vista and Windows 7. On those systems, files requiring write access while the program is running are moved to a new data folder located in the user profile, eliminating the need to run the program with administrator rights or to install it at a particular place.
      Nothing will change on Windows XP (or earlier) systems. In the case of an upgrade from RXCLUS 8.4x running on Windows Vista or 7, the existing personal databases will be copied to the new data folder the first time the version 8.5 is started, so you won't loose any existing information.
      The "About" window will display the full path of the data folder:


    • Your LOTW credits can be imported directly from the ARRL server to your personal DXCC database if an Internet connection is available. Several options give you full control of the import process:
      - full download of your credits or incremental download based on the date of your last request
      - keep the downloaded files on your disk after the import or not
      - import only credits for some of your calls. Those settings appear in a new tab in the options, named LOTW(2):

      For security reasons, the password is displayed as *'s and saved encrypted with a basic algorithm. It's also not included in the export which can be done with Tools --> "Export users settings".


    • In addition to the LoTW users list, more files can be updated directly from RXCLUS web site if an Internet connection is available: COUNTRY database, personal IOTA database, and Telnet directory:


    • Alarm priority between paper and LoTW confirmations can be changed. Earlier versions of RXCLUS always gave priority to paper QSL's. This means you got an alarm if you had a country not confirmed on a band or mode by a paper QSL even if it was already confirmed by a LoTW credit.
      With the new option "Same priority for LoTW and paper QSL's", the program won't make any difference between paper and LoTW QSL's, so you won't get any alarm as soon as you have one of those kinds of confirmation.
      The option "Alarms only for LoTW" was implemented for those who chase only LoTW confirmations and are not interested in paper QSL's. This means the program will ignore the paper QSO/QSL status and issue alarms based only on LoTW credits:


    • ADIF numbers (required for importing log files into your personal DXCC database) were moved to the COUNTRY database. This will allow the addition of future new DXCC entities without having to release a new version of the full program. But, as this feature was missing in older versions, you have to upgrade to version 8.5 to be able to import contacts with the 4 new PJ entities.


    • The country information window now also displays the QSO and QSL status for both paper and LoTW confirmations. Colors used for this purpose can be configured in Options - Color, especially for those who can't distinguish the red and green colors used by default:


    • DX spots can be filtered also by logger call or by keyword in the comment field:


    • The IOTA database is now displayed in the alphanumerical order of  the continents (AF, AN, AS, EU, NA, OC, SA), no more with EU at the beginning (which was the standard in the early days of the IOTA program).


    • Personal DXCC and IOTA databases can now be backuped to any drive and directory, not only to a (usually no more available) floppy disk.


    • Lists in the options (additional LoTW users,.) can now be sorted alphanumerically.


    • Audible alarms can be restricted to seeked calls:


    • Fixed a severe bug which made the ADIF import procedure crash if large records (over 700 characters for a single QSO) were present in the log file.


    • The font used to display the databases can now be configured. This applies to those windows: DXCC and IOTA (incl. stats), SHOW/DX (+ANN/CHAT/TALK/WWV), search results (ANN/CHAT/DX/TALK), Telnet directory and the status bar of the main window. This is meant for those who get unreadable texts with the default Fixedsys logical font, which should not be modified in "normal" situations as most windows are optimized for it.


    • Better compatibility with Windows large fonts (120 ppi). But the extra large fonts (144 ppi) in Windows 7 are currently not suppprted.


  • Added support for the experimental 600 m band (DX spots on 493-510 kHz will be recognised as legitimate ones and stored in the DX database, while the search window now includes an entry for this band).
