If you attempt to download the "latest CAT commands file" from: https://www.varac-hamradio.com/rig-control-file It will attempt to open this page, but will fail, repeatedly, in both Brave and Edge browsers: https://www.varac-hamradio.com/forum/manuals-troubleshooting/rig-control-cat-command-file-cat-customization-guide I saw an 'out of memory' error from the web page at one time. Thank you! Chris Shaker, KJ7BLE
