If you need a debug build, you’ll have to build it yourself, but it isn’t too difficult. Anyone with a debugger already installed and configured can probably do it.
You can get debug-level logging using the --debug startup flag or by just checking the debug checkbox in the log window.
Not being able to reconnect is a feature of the radio, by design they do not allow one to connect until you have either properly disconnected (which does not happen if the connection hangs of course), or, you have to timeout (typically 5-10 minutes). You can also just reboot the radio. It’s annoying but we can’t do anything about it.
Perhaps you’ve got network problems. Since the latest firmware for the rig is 1.32, perhaps you might update that and see if it’s a rig issue that’s been fixed in firmware.
