The \"issue\" is gone after my mod.\n\n*But be careful:* FIRST set a pure carrier tune signal with low power, that the PA can detect the band reliable (this works in this case) - that ALWAYS has to be the FIRST STEP if changing the band too ! AFTER this you can transmit in SSB or other modes.\n\nMy mod is only allowed under this condition, because my mod remove the protection, which is causing the issue with SSB. A wrong band selection can damage the LPF capacitors !\n\u003chr\u003e\nIf you want to use my mod, you confirm the following:\u003cBR\u003e\nNo guarantee, no warranty !\u003cBR\u003e\nYou do all at your own risk !\u003cBR\u003e\nYou know, what you do and why !\u003cBR\u003e\nOnly for use in amateur radio, because you need to be a licensed hamradio operator !\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdl1bz%2Fnepcontrol50w","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdl1bz%2Fnepcontrol50w","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdl1bz%2Fnepcontrol50w/lists"}
