16 March 2021: After a 14-year hiatus, we are pleased to announce that EchoLink for Windows version 2.1 is now available. Please see the Download page to download. The changelog is shown below.

Latest Features

Current Version: 2.1.109

2.1.109 (March 18, 2021)

  • Fixes an issue that could prevent stations calling CQ from being able to connect to each other.

2.1.108 (March 16, 2021)

  • New "Call CQ" feature (also to be rolled out on Mobile app editions), including DTMF code to activate
  • Automatic Proxy selection option

  • Option to enable a continous subaudible tone to keep VOX-driven devices keyed consistently throughout each transmission.
  • Smarter handling of connection message protocol to improve connect reliability after IP change
  • Removed support for, and mentions of, dial-up networking
  • Option to show timestamps for each message in text-chat window
  • Fix for not muting conference audio during playing of Welcome message to newly-connected peer.

  • Added "Reset to Defaults" button on Setup->Timings tab; adjusted numerical validation ranges.
  • Extended maximum length of Name field to 18 characters.

  • Fixed problems with displaying Asian characters in Chat window and Station List.

Upgrade Notes

If you are upgrading from an earlier release of EchoLink, please note the following:

  • EchoLink 2.1 runs on Windows Vista and above (for example, Windows 7 and Windows 10). Windows XP, and editions prior to XP, are no longer supported, nor recommended. Please use the prior version if you are running a very old Windows edition.
  • If you are upgrading from 2.0, please note that any Countries you may have selected in the Security tab (under Preferences) will not be carried over, and must be re-configured.
  • It is not possible to downgrade from 2.1 to 2.0 using the Installer. If you've upgraded to 2.1 and wish to revert to 2.0, you must un-install 2.1 first. (Your configuration settings will not be retained and will need to be re-entered.)


  • If you can see the list of stations, but are having difficulty connecting to other stations on EchoLink, please read the section Firewall Solutions.
  • Stations which have just come online, or have just changed status, are highlighted in yellow in Index View.

Known Bugs

  • Version 2.1.108 contains a bug that can prevent stations that are calling CQ from automatically connecting to each other. This is fixed in version 2.1.109.
  • If you are using a high-resolution display (such as a 4K monitor) and you have chosen text scaling higher than 125% in your Windows Display settings, the EchoLink application might not size itself correctly. This will be fixed in an upcoming release, but as a work-around, you can set the Compatbility properties for the EchoLink application to override High DPI scaling behavior, with scaling to be performed by the System instead of the application.
  • Integration with UIView32 is no longer supported, as of version 2.1. However, this option still appears in the Help file and as an option in the APRS configuration on the RF Info tab. An error message will be displayed if UIView32 is selected in the TNC Interface drop-down.
