    Thanks Mike, these videos really help us get the most from our Flex radios. NM9P also did a set of videos on this topic. He goes into some good detail, and I recommend them highly. 73, Len, KD0RC

    Mike,

    What happens if after using FDX I forget to set FDX off and use the same ANT on slice A for RX and TX in normal operation (100w)? As per Flex manual, it seems that even with FDX on, RX is muted if TX antenna is the same as RX antenna.

    That is correct Paulo.

    @Paulo CT1ETE

    You won't hurt the radio. It has protection circuits.

    Keep in mind that every HF radio I know has RF coming down the antenna right to the front end amplifiers even if you are not receiving on that frequency. Even if the radio is off.

    Think about it. :)

    Hi Mike,

    Thanks for the reply. I was afraid because I think I saw some kind of calculation for FDX power to be used not to damage the SCU, but I believe that is with a different antenna on RX.
