No ATU & No RF output on Transmiter

I bought the Flex 6600 on July 23 and am using it. But suddenly today, autotuning is not working and RF output is not working. It is the same phenomenon even if the factory is reset. Is there a way to set it up?

    I created a support ticket for this.

    Did the RF Power slider and the TUNE Power slider default to zero?

    RF Power Slider 100W, TUNE Power Slider is set to the default of 10W. There is no change in settings, but suddenly the ATU is not working properly.

    I know there is a support ticket open, but does the ATU work ok when a dummy load is attached? Do the meters show output on a dummy load?

    The built-in ATU of the Flex 6600 model doesn't work properly, so I'm using a TGXL external tuner model, which is inconvenient because it can't be operated remotely with the iPhone app. I bought Flex-6600, PGXL, and TGXL together for wireless operation remotely, but I'm disappointed that I can't do remote operation that easily.

    You can use the TG XL remotely from iPhone using Node Red to control it. More information on the Node Red for Ham Radio group.

    check out the WiKi section on installing Node Red on a Raspberry Pi. Then the file section. I have flows for Flex radio, Power Genius, Tuner Genius, and Antenna Genius.
