The \"issue\" is gone after my mod.\u003cbr\u003e\r\nAdditional I replace with this modification the automatic band detection through band select with bandvoltage output from the Hermes-Lite 2.\u003cbr\u003e\r\nThat means, you LOST the original automatic band selection through the frequency detection. But with bandvoltage as option an automatic band select is back again.\r\n\r\n__All code refers to my schematic. You need to look in for understand all.__\r\n\r\n## Webdashboard as option\r\n\r\nI implement Wifi and a webserver with websockets for show the status of the amp in a webbrowser as an option.\u003cbr\u003e\r\nDefault this option is deactivated.
